What is HDR and how it can help make your photos beautiful

Owners of the latest smartphones have probably seen that they have an HDR (High Dynamic Range) photo app. experienced users know what HDR is, but not everyone understands how and in what cases this function is best used. In the heading Instructions We will try to clear up some confusion and show you how to get the most out of HDR when shooting on a mobile phone.

As you know, the human eye can see much more high dynamic range scene than any camera, do not speak already in the cell phone camera. We can equally well distinguish small details of a dark building against a background of a bright sky and, for example, an airplane flying high above it. But we all know what happens if you take a photo of a building with your phone: it turns out to be too dark with very poorly distinguishable details.

Photo with exposure across the sky

Of course, we could try to eliminate this problem by setting the exposure on the building itself, highlighting the area with it on the screen. With this approach, the décor of the building is visible well, but the sky in the photo has turned into an overexposed, blurred white spot.

Photos from the exposition of the building

Our goal is to combine the best characteristics of the two photographs, creating an equally beautiful image in which both the building and the clouds look great. This is exactly what HDR technology offers. Photos taken with HDR are essentially multIPle merged images taken at different exposures.

The default IPhone application for taking photos has built-in HDR functionality. You can turn on HDR by clicking on the option button in camera. When HDR is on, IPhone will automatically take HDR photos. Please note that this takes longer than normal shooting.

However, the built-in IPhone app provides quite weak result, and you will be able to take much better pictures when using Special Programs.

Photo taken with Pro HDR on IPhone 5 photo taken with default app on IPhone 5

One of the most popular and convenient HDR photo apps is Pro HDR (for iOS. 66 rubles; for Android. 61.75 rubles). However, there are also free versions with limited functionality.

The Pro HDR app offers two modes: automatic and manual. If you choose Auto, the application will analyze the scene, take a frame with a dark exposure (with more detailed highlights, but less detail in the shadows) and a light exposure (with more detailed areas in the shadows, but little detail in bright areas) and combine the two images.

Some photos may not look natural enough. To add realism to your shots, use the five sliders in the simple and intuitive settings panel. They allow you to adjust brightness, contrast, saturation, warmth, and hue. Automatic mode is fine for most situations; manual mode is only necessary when shooting the most contrasting scenes.

Settings panel interface in Pro HDR

Please note that HDR photos do not always look better than those taken in standard mode. Try to keep both HDR and normal pictures to then choose the most successful of them.

Using HDR mode is inappropriate when shooting in motion. Due to the fact that HDR combines multIPle exposures of the same scene; and if these very scenes change, in the end you will get the most unpredictable result. Try to shoot with something stable or using a trIPod.

Receiving a pension for health reasons: disability registration

Early retirement allowance is payments every 30 days, which the Russians begin to transfer NOT earlier than 2 years before the established age of retirement. Such allowances can be received by citizens who are registered in the Employment Center, and persons who have worked for at least 20 years (applies to Russian women), 25 years (applies to the stronger sex).

Severe working conditions are those that affect a person: loud noises, radiation, vibrations, high or low temperatures, microorganisms, hazardous chemical components. In the presence of dust and dirt in the workplace, a poor-quality light source, high humidity, work is considered hazardous to health and harmful.

Early retirement benefits apply to miners, railway workers, drivers of public vehicles, teachers, doctors, miners. Also, the Russians who work in the metro, prisons, aviation and search areas are waiting for an early exit to a well-deserved rest. Before the deadline, the blind, midgets, dwarfs, Russian women, who are raising more than 3 children, can write an application for leaving their place of work.

Experts told whether it is possible to retire early for health reasons. If a Russian is constantly feeling unwell, he should seek qualified medical help. A medical and social examination will be appointed, after which it will be possible to issue a disability retirement pension. The specifics of the design of this payment are spelled out in federal legislation. It is received by persons with disabilities (groups 1-3). Sometimes a Russian can expect to receive 2 pension allowances: labor and social.

Disability Insurance Benefits are assigned to individuals who have an Appropriate Status. At the same time, it does not matter how many years a person has worked, whether he is employed now or not. To apply for a pension ahead of schedule for health reasons, you should contact the MFC or the Pension Fund. The employees of the organization will once again clarify the list of documents that are needed to apply for a pension. It is imperative that a citizen will have to write a statement, SUBMIT originals and copies of a passport, doctor’s opinion, work record book (if any).

The condition for early retirement for health reasons is the status of a disabled person and the presence of at least 1 working day (if it does not exist, the person will begin to receive social benefits for disability).

Early retirement pension in the Russian Federation: registration procedure

What actions need to be taken to register early retirement benefits? To begin with, it is worth contacting the local Employment Center with an appropriate application. They will give you a document that you need to fill out. The authority will definitely help you to arrange the paper with high quality. Within a month, the Employment Center will provide the citizen with an answer. with the consent to carry on further work or with a justified refusal.

What do I need to SUBMIT to the Employment Center besides the application? As a rule, these should be the following documents:

• Passport and its photocopy;
• Military ID;
• Birth certificate of the child (if the employee has children)
• Original and copy of work record book.

Also, the Employment Center can invite the following papers:

• Certificate of dependents;
• Address application (about place of residence)
• Disability certificate;
• Certificate of the upbringing of a child, and not reached the age of eight;
• Family composition document;
• Identity or certificates of guardianshIP.

The authority can also invite many other certificates. for example, individual documents from work. It is very important to correctly and correctly draw up all the papers, check the presence of seals and signatures.

In early retirement

The company where I work is being liquidated. By the retirement age I miss 6 months. It is unlikely that it will be possible to find a job at this age. I heard that there is a provision on early retirement. Please clarify the law on this issue. N. T. Ilyin (Kursk).

The head of the department for supervision over the legality of legal acts, observance of the rights and freedoms of citizens of the Kursk Region Prosecutor’s Office Tatyana Efimova is responsible: Part 2 of Article 32 of the Law of the Russian Federation No. 1032-1 of April 19, 1991 Employment of the population (as amended on June 3, 2009.

When is an early health pension given

Pension assignment for a personal account

You can now apply for early retirement remotely: using the Pension Fund website or your personal account on the State Services portal. The fate of such appeals has already reached 70%.

Personal accounts for pensioners are filled with information on the length of service and wages by the pension fund in advance. Therefore, a personal visit does not require registration of pensions in this period of time.

Categories of citizens

An early retirement pension is called the option of receiving monthly payments, in which the onset of the permitted age will take place NOT more than 2 years later. Persons who are in the Russian employment center as unemployed, as well as those who have the relevant work experience (20 years for females and 25 years for males) can apply for such a pension. Accordingly, early retirement pension in the Russian Federation is issued only for those persons who meet the above criteria.

Separately, it is worth noting the presence of some serious illnesses in the working person. If the continuation of work activities is impossible for health reasons, then an early retirement pension can be issued only on condition that a special medical opinion is submitted to the employment center.

Federal Law of the Russian Federation No. 400 contains more than 20 clauses, which indicate both the conditions for retirement and some professions in which one can apply for early retirement. What exactly is worth highlighting here? Here are some of the specialties specified in the law:

• Railwayman;
• Search engines and geological prospectors;
• Miners;
• Public transport drivers;
• River and sea shIP workers;
• Aviation workers;
• Rescue workers;
• Persons working underground (miners, underground workers, etc.);
• Penitentiary workers (prison staff)
• Educators;
• Community physicians;
• Theater figures and some other workers.

In addition to everything GoPro, there are also special categories of citizens:

• Mothers with many children (raising more than five children)
• Visually impaired;
• Persons Injured as a result of hostilities;
• Dwarfs and midgets;
• Far North workers.

The question of how to retire ahead of time is regulated by many Russian federal laws. What are the rights of a citizen who has retired early?

A citizen is able to demand from his employer all the necessary documentation required for transfer to the employment center or the Pension Fund of the Russian Federation. over, the employer of the enterprise must confirm the Employee’s preferential length of service. If the employer for some reason does not do this, then such a task is assigned to the Relevant state body.

As soon as the employee receives the insurance pension certificate, all information about him displacements will be accounted for by the Russian Pension Fund.

• ФВ. basic payment;
• С. the cost of one coefficient at the time of registration of the pension;
• PC is the total amount of Pension type coefficients earned;
• K. raising indices to PV.

Conditions for registration of an early pension

How to apply for an early retirement pension in the Russian Federation? To get started, pay attention to the following conditions:

• The age of the employee. It must be at least 53 years old for women and 58 years old for men.
• Unemployed status.
• Compliance with the length of service established in the category.
• Personal expression of the will of the person applying for early retirement (if the person was laid off).
• If the applicant is a mother raising more than five children.

If the relevant conditions are met, it is worth paying attention to the so-called lists 1 and 2, which are mentioned above. So, a woman belonging to the list of list 1 is entitled to a pension upon reaching 53 years of age, with a total work experience of 15 years. At the same time, the duration of work in hazardous industries should not be less than seven years. In accordance with list 2, a woman can apply for a pension from the age of 45. At the same time, work experience should NOT be less than 20 years.

And what do the lists say to male workers? In accordance with list 1, a man who has reached 50 years of age can apply for a pension accumulating 20 years of experience. Schedule 2 sets the minimum age of an employee at 55 years and 25 years of work experience (12 under harmful conditions).

Thus, early retirement pension can not be issued by all persons, but only topics that meet the above criteria.

List of harmful professions

If an employee carries out his labor activity at work with harmful work habits, then the possibility of early retirement increases significantly. Which professions fall under the category harmful? Since Soviet times, a classification has been preserved that allows you to accurately determine the severity of labor. So, there are four levels of professional activity:

• 1 degree. Implies minor changes in the body, which quickly pass when a person stops working.
• 2nd degree. It is characterized by the presence of persistent changes in the body, leading to the development of chronic ailments. This is especially true for persons working for harmful production for over 15 years.
• 3 degree. Working with such a level of harm entails permanent destruction of human health; total disability remains possible.
• 4 degree. Denotes a complete functional disorder and the presence of other processes harmful to the body, entailing disability.

The issuance of each such degree is possible only if attention is paid to the following points:

• Increased dust in the air, the presence of dirt;
• Poor quality lighting;
• Loud noises;
• Harmful radiation;
• Work with harmful microorganisms, viruses, bacteria, chemicals, etc.
• Increased vibrations;
• High humidity level;
• Too low or too high air temperature;
• Duration of stress in work activities and much more.

One more classification comes from all the criteria presented: list 1. these are professions with a critical degree of harmfulness, and list 2. certain types of heavy professions and positions. Both of these lists can be easily found on the official website of the Ministry of Labor.

Pension registration

Due to the Pandemic, the pension fund simplified the procedure for assigning a number of benefits, as well as registering pensions.

A little about technology

Many digital camera owners have heard of HDR technology, but not all of them understand how it works. So what exactly is HDR? The human eye is truly a miracle of technology. Unlike cameras, it easily adapts to changes in lighting up to 24 stops of exposure, thanks to which we can distinguish fine details equally well against dark and light backgrounds. The dynamic range of most digital cameras is much lower, it is difficult for them to adapt to the light, so they only capture well areas with a certain level of illumination.

So, if we succeed in capturing a dark building against the background of a light sky, the latter often turns into a blurry whitish spot and vice versa, if the light sky comes out well, the detail of the dark building is lost, and the area of ​​the photo on which it is located turns out to be noisy. These flaws are especially evident in photographs taken with imperfect mobile phone cameras. HDR technology is aimed at eliminating this shortcoming. When using the HDR mode, the camera takes a series of shots with different shutter speeds and exposures, while autofocus during the shooting is alternately concentrated on areas with different illumination levels and distance from the lens.

Having created several frames, the camera then combines them with the software method into one saturated and detailed image in dark and light areas. This is the key difference between HDR shots and regular photos. The quality of the resulting image depends on the aLGorithm used. Less quality photos are obtained, in which the images are simply superimposed on each other and slightly shaded. To obtain HDR photos of higher quality, various sections of the frames are additionally analyzed in order to identify the most successful.

What you need to know when shooting HDR

Use HDR mode when shooting landscapes, single subjects, and for detailing in low light conditions. It is strongly recommended to use a trIPod in order to avoid shifting and, as a consequence, misalignment of frames when shooting. But for photographing moving objects, HDR shooting is not suitable, since the photos will turn out to be blurry.

It is preferable to create HDR photos in the classical way with the introduction of manual settings and third-party desktop programs, in this case the photo is of higher quality. At the same time, if the original images were created in RAW format, tone compression will be required, otherwise the HDR photo will look somewhat unnatural on computer monitors.

In-camera HDR shooting. what is it?

The contemporary art of photography is not only about capturing the beauty of the moment or capturing the subject in the best possible angle. Many photographers today strive to enhance their photos by passing them through various filters and adding Special Effects. One of these effects will be discussed today. It is called High Dynamic Range (abbreviated as HDR) or high dynamic range.

HDR TVs

HDR technology today is supported not only by cameras, but also by some TVs with 4K resolution, for example, Vizio P50-C1, Sony XD8005 or Samsung KU7000. The picture in such TVs has more saturated colors, dark areas look even darker, and light ones look even lighter, due to which greater detail is achieved.

However, HDR support in a TV is not at all what HDR support in cameras. If in cameras the effect is applied at the moment of creating a photo, then in TV. at the moment of showing the picture. In fact, this means that in order to obtain the HDR effect, the content itself must initially support, which is currently very small.

HDR mode in camera phone and camera

When working with a camera, there are two ways to create a high dynamic range photo. The first is more complex, longer and is used mainly when shooting with professional digital cameras. Its essence is as follows. The photographer takes three to five shots in Bracketing mode, and then stitches the resulting frames on a computer using Photomatix or another similar program. Then the resulting image is optimized for correct display on displays.

But there is also an easier way to get HDR photos. Many modern cameras, including those built into phones, allow you to shoot HDR in automatic mode. The camera does everything for you. She herself sets the required exposure, takes continuous shots herself, glues and processes the resulting frames herself. In Nikon cameras, for example, you can enable the HDR option in the Photo Shooting Menu. HDR. HDR mode. On.

The automatic HDR mode in a smartphone works on the same princIPle. The phone’s built-in camera takes two or three frames and immediately saves them into a single JPEG image. As a rule, HDR in the phone camera is enabled in its settings. In some models of accessories the option is located in the subsection of effects, in others a separate icon next to the flash is provided for its activation. Often, the options provide the ability to manually adjust the exposure.

HDR imaging software

It is important to understand that you can get real HDR photos only by merging and processing several frames taken with different exposures, and it does not matter whether the photos are created manually or automatically by the device camera. As for creating HDR images from regular JPEG or even RAW files using programs like Dynamic photo HDR or Photomatix Pro, then in this case we can only talk about giving a high dynamic range effect, but perhaps not creating a Full HDR.

It is impossible to create an HDR photo from 8-bit images, which you usually have to deal with on the Internet, nor can you create it by lightening shadows and darkening highlights from one RAW file. In either case, the resulting file will be a pseudo HDR image. Nevertheless, using applications such as EasyHDR, Photomatix Pro, HDR Efex Pro, Adobe Photoshop, Dynamic photo HDR, Corel PaintShop Pro and the like, you can give ordinary images like HDR, improve color, add a surreal effect to them.

SNAP camera

Perhaps, everyone who set themselves the task of choosing a good photography program for themselves came across a solution from the developer Marginz Software. Snap Cam enjoys well-deserved popularity among many, which is explained by several factors. Among them are support and timely release of new versions; some features are unique; the program has incorporated almost everything that may be of interest to both a professional and a beginner photographer. In particular, it is when working with it that it is easiest to understand what HDR is in a phone camera. To activate the mode after installation and launch, select HDR by rotating the graphic settings wheel (version 7.X.X). It remains to take a picture. By default, three frames with different exposures will be saved, among which you can choose the best one. The function of saving intermediate pictures, if it is not needed, is deactivated in the settings. section HDR. In this case, the entire shooting process takes place completely automatically, except, of course, pressing a button. Lovers play around with settings, focusing between intermediate frames, as well as milliseconds of delay, may be interested. The program allows adjusting the clarity, brightness, image resolution, cropping, etc. It is assumed that you purchase a license.

HDR Pro

Within the framework of the article, it is useless to try to describe all the existing programs for smartphones in which the shooting mode with an extended range is implemented, since there are dozens of them.

Nuances of use

At the same time, it is important to understand that HDR mode is still not a panacea. Even using it, the owner does NOT become a professional photographer. The main problem is as follows: since the final image is formed from several intermediate ones, the apparatus itself and objects in the frame must be motionless.

The next feature that should be taken into account is that in some cases, obtaining a picture with an average brightness is inappropriate. For example, silhouettes in the twilight, as conceived by the photographer, Should remain the same vague shadows, and not people in gray raincoats. HDR shooting does not allow for this.

Finally, the brightness and contrast of images taken in this mode are generally slightly lower than in photographs taken in the usual way. Sometimes it turns out to be quite critical.

What is HDR in a phone camera? High Dynamic Range. Expanding the dynamic range of a digital image

The desire of smartphone manufacturers to make their products more attractive to buyers has led to the fact that it is now quite difficult to find a device that does not have a built-in digital camera. Dozens of megapixels, sophisticated image processing aLGorithms, automatic range adjustment It would seem that it is enough to select the desired frame and press the button, and the rest will be done by automatic.

Basic functionality

The demand for HDR mode has led to the fact that more and more smartphone manufacturers have begun to include in their operating systems an application for working with a camera, which initially provides the ability to take pictures with high dynamic range. True, when using stock (basic) solutions, it says about the abundance of any additional settings. For example, in the popular CyanogenMod build, clicking on the three dots of the menu opens a window where you can enable or disable the use of HDR mode. Parallel operation of this function and the flash is not possible. It should be noted that very often an inexpensive phone with a good camera, shooting in normal mode, allows you to get better quality photos than more expensive, but with a low-quality matrix.

What is HDR in a phone camera

In fact, the princIPle of operation of this mode is quite simple. HDR shooting assumes that the camera takes not one, but several frames at a time, while focusing in the background on objects with different light levels.

“Open camera

Exactly so. Open Camera. is the name of an application that also deserves the closest attention from photography lovers. There are no less settings in it than in the above Snap. True, to activate the HDR mode, a beginner has to study all the items in the settings. Actually access to magic button can be accessed by clicking on the dot icon in the top on-screen menu. Among the items on the list Scene there is HDR. The image quality is excellent, but the processing speed is one of the slowest among Similar solutions. Perhaps, in models of smartphones with powerful processors, this delay is leveled. To understand what HDR is in a phone camera, it is recommended in practice to select different shooting modes and compare the result.

Is HDR so useful

Given the current trends in new profit ploy, mobile device companies are ready to seize every opportunity to increase the value, prestige and competitive advantage of their products. However, the technology has taken root and is present in the cameras of many mobile phones, especially for expensive models and flagshIPs, starting with the Samsung Galaxy S4 and the IPhone.

What is HDR in a phone camera and why is it needed?

What is HDR in a phone camera? Almost every owner of a smartphone with a similar function has probably asked a similar question. Depending on specifications and other factors, some users may NOT be able to tell the difference between the photos taken when the HDR function in the phone’s camera was turned on and compared to regular photos. However, there are still differences and they are significant.

Where is applied

Having answered the question what is HDR in a phone camera, many will probably ask the following question: why is it needed? In addition to brighter pictures, this technology is used in many mobile applications with filters for photos. Various special effects that are associated with changes in shadows, contrast, anti-aliasing or blurring may also include the use of this function.

However, it is very important to have a good high-resolution display, since not all screens can fully reproduce the image that results from using HDR. It is possible that some budget smartphones can take pictures using high dynamic range, but the photo will not differ much from the usual.

What is HDR in a phone camera?

If you do not delve into the technical difficulties, then this is a special format for processing photos at the time of saving images. NOT taking the complexities of programming as a basis, this function allows you to take pictures with more vivid and contrast. This happens due to the expansion of the brightness range, which is not always visible with the naked eye or using ordinary photographs.

In addition, the enabled HDR function in the phone camera affects the file size, due to the peculiarities of saving the received images. This aspect is also present on other devices, for example, cameras.

HDR abbreviation

It stands for High Dynamic Range. If translated from English, then it will mean a high dynamic range. However, the full name of this technology did not really catch on, in contrast to the abbreviated version. In general, the name reflects the essence of the technology. It allows you to increase the brightness range and color depth.

Pros and cons of this feature

Trying to understand what HDR is in a phone camera, you will probably come across the fact that the pictures taken with the introduction of this technology begin to have a very large volume, that is, take up a lot of space in the memory of your smartphone. For devices where there is a large amount of storage space, this feature does NOT create any breakdown. In this case, we are talking about gadgets, the memory of which is equal, for example, 128GB or even more, due to flash drives. But in the case of smartphones with small storage, the HDR function will lead to fast overflow and lack of space. Of course, this is not critical, but constant notifications about insufficient memory can annoy and interfere with users during their work.

HDR function in the phone camera. This is not only a way to advertise additional features of a smartphone, but also quite an interesting technology that will allow you to experiment from a picture.

There are a large number of photographs on the Internet, mainly of nature and various landscapes, which are made using high dynamic range. They are very saturated with bright colors and reproduce a wide range of different colors that fall into the lens.

HDR technology can be used Not only in mobile devices, but also in professional cameras, which gives photographers more creative tools. In addition, there are TVs that support this function, they make the picture more lively and vivid.

Thus, the answer was given what is HDR in a phone camera, as well as what is the essence of this technology, regardless of the devices on which it is applied.

Cons of HDR mode

Optimization delays framing and overloads the smartphone chIPset, consuming computing resources. But you can put up with these shortcomings. After all, almost all applications hang and hang the chIP. However, the HDR mode, activated in the smartphone camera, has more serious disadvantages that limit its scope.

First, we are talking about the impossibility of fixing Dynamic objects. Simply put, humans, animals, vehicles and other moving animate and inanimate objects cannot be filmed using HDR on a phone. This will give you blurry spots instead of a clear shot, because the subject moves towards the photographer.

Secondly, active HDR in a smartphone camera suppresses, or rather, averages the brightness of the frame. The simplest processing aLGorithm involves the trivial overlaying of puzzle pictures in layers, so a picture without active dynamic mode will have a brighter foreground or background than in an HDR frame.

And the speed of the smartphone camera with active HDR suffers greatly. This is especially noticeable on gadgets with weak processors, which cannot boast of computing speed. Some owners of such phones even claim that it is easier for them to take 5-10 simple frames and choose the most successful one from them than to wait for the HDR image to be processed.

All this, of course, imposes its own restrictions on the practice of using the HDR mode in the phone.

How HDR works

The HDR mode in the smartphone camera is realized through the use of software and hardware. The former are responsible for post-processing, and the latter are responsible for the accumulation of information.

Of the smartphone camera hardware, the autofocus module is most involved in HDR. It is he who directs the lens alternately at the objects of the foreground, then at the elements of the background. In addition, the brightest / darkest objects, as well as elements of the frame with different contrast ratios, attract the attention of the automatic focus. They all act like in focus, and in defocus mode.

In addition, HDR also puts a load on the mechanisms responsible for the shutter speed and exposure of the smartphone camera. All shots in the series are shot with a different exposure period, so the electronic shutter also works to create the perfect shot along with autofocus. Variable intervals during which the shutter transmits light to the sensor can enhance both the light and dark areas of the image. The former are shot with a short shutter speed, and the latter with a long exposure.

Example. When shooting a cityscape or landscape on a sunny day, as well as when shooting in the evening, there is one difficulty. Well-lit areas will come out overexposed by exposing shady areas, and vice versa., shadow it will be too dark if you optimize shutter speed and exposure for highlights. HDR allows you to take multIPle shots. some with ideal shadow settings, others. with settings for highlights, and then collect the Perfect frame (as much as possible). As a result of all THESE dances with a tambourine, the light areas will turn out a little darker, and the dark ones. a little lighter, which is clearly seen in the example of a picture from the Google Pixel camera. (In-camera HDR is enabled in second shot).

After the accumulation of information, the second stage of HDR work on the phone is turned on. processing the received puzzle frames and forming a picture from them with perfect detail and picture clarity. For this, special aLGorithms and programs are written, optimized for the capabilities of the processor chIPsets and camera characteristics (shutter speed and autofocus aiming speed, sensor light sensitivity, camera lens aperture, and so on).

After reworking the puzzles, the user gets a ready-made picture with improved characteristics. In this case, there is no way to delve into intermediate frames; for the owner of a smartphone, this whole procedure looks like displaying a picture on the screen with a slight delay.

What is HDR and how HDR works in a smartphone camera?

High Dynamic Range (abbreviated. HDR) mode has appeared in smartphone cameras recently. However, the novelty of the technology did NOT prevent HDR from penetrating both expensive flagshIPs and mobile devices with more modest capabilities. But is this mode as good as smartphone marketers say it? Let’s try to deal with this issue and find out who and when will need High Dynamic Range.?

What is HDR

High Dynamic Range (high dynamic range) is a special mode of operation that starts shooting a series of frames with subsequent processing of the results. The result of processing is one single snapshot, Assembled like a puzzle from the most successful pieces of the series.

The presence of the HDR mode in the phone allows you to take good shots Not only in ideal conditions. The fact is that each of the pictures in the series, taken apart into puzzles, is taken at different camera settings. In total, one part of the frame is better, and the other is worse.

Then a special aLGorithm collects from the Most Focused, Contrasting and Sharp Puzzles an Actually perfect frame, suppressing all noise and increasing clarity and saturation. This is how the perfect shot is formed in non-ideal conditions.

Who needs HDR and when

You should enable HDR on your smartphone camera in the following cases:

We are drawn to such conclusions by analyzing the advantages and disadvantages of the High Dynamic Range mode. Well, if our readers have their own opinion, supported by practical experience, then they can Supplement our conclusions in the comments to this article.

Pros and cons of HDR

The advantages of using the mode include the creation of a detailed and clear image. If you capture a beautiful sunset, you can get dark buildings in the frame.

It will focus the sunset first, then the houses and then the small details of the environment.
Along with the positive aspects of using the regime, certain disadvantages should be highlighted:

• Decreases the brightness level of the image. Due to the multifaceted processing, this parameter is averaged;
• Motion blur. For the reason that the mode for processing takes sequential snapshots, in order to get the desired result, the objects must be static. Abrupt rushing movements can lead to a lack of clarity;
• Reducing the speed of the photo execution technology. The device has to photograph objects and immediately processes them. This automatically Reduces the speed of taking pictures, especially if there are many of them. here are 7 to 10.

Accepting the described functionality, it should be noted that this is an additional option, but not a solution to problems associated with taking a photo.

What is HDR?

This photography mode helps you take shots with contrasting contrast. The elaboration of details will not be lost. The functionality depends on the brand of the smartphone and on the type of SoC. In this case, the general operating mode is considered to be the same for all phones.

After starting the mode, the camera takes several photos, differing in shutter speed and exposure. After shooting, the pictures are combined with each other, as a result of which a single image becomes clear, contrasting and detailed.

When shooting

Required during shooting Make sure that the smartphone has settings for ensuring a clear image. By carrying out this process, the camera gives the following positive factors:

• Adjust the amount of light to reach the camera matrix;
• Assembly allows you to efficiently handle light and dark areas;
• It is possible to use the software part of the smartphone;
• The completed ones are assembled and processed to obtain an optimal result;
• Allowed to use single-chIP software system.

The functionality and mode of operation make the device popular among users.Which is filmed on the phone turns out to be rich and colorful, the natural colors are preserved.

How to enable HDR in the app?

To start the mode on the phone and make it active, you must perform the following manIPulations:

• The Camera application is launched on the smartphone for shooting.
• In the upper right corner, you should find the HDR inscrIPtion.
• After clicking on it, the attention will be presented with a list of switches for turning the function on and off.

The smartphone user independently decides in what situation to launch the mode of taking pictures, and when it is necessary.

How HDR stands for abbreviation?

This abbreviation will stand for High Dynamic Range. In Russian, this expression means High or Extended Dynamic Range. In fact, this is the ability of cameras to simultaneously transmit light and dark details into the captured image.

This range is able to determine how well the camera detects individual tones that lie between black and light areas. If in the process of shooting details, light elements merge, in such cases they say that the range is narrow.

When taking pictures

During the operation of the mode, a serious load falls on the camera. Among the other features of the mode, the following should be highlighted:

• Before image processing, the hoof camera provides information about the general scene and the details placed in it;
