The modern photographer is offered many opportunities to perform photography correctly. Cameras are equipped with many different types of E x-Emerg. Each of them is designed for a specific lighting and task. You just need to figure out how to measure exposition measurements in photos, the pros and cons of the different types, and how to choose the settings for your particular situation.

What is camera emporam
The inspector is the calculation of the exposure needed to produce an image. The camera measures the brightness of the scene being photographed in several ways. There are three types of exhibitors
- Point or partial exposuresm;.
- Matrix exposurem;
- The central expert.
For the correct choice of camera exposition settings, whether the scene is properly illuminated or not, whether a portion of the frame is overweight or vice versa, failed dark.
Point and partial exoport cameras
These are two different types of exposure definitions, but there is one operating principle. They evaluate a small portion of the frame. In most cases, they are often close to the center. The point type analyzes 1-5% of the photo. portions – about 15%. Some camera models allow the exhibitor area to be moved from the center to other parts of the photo.
The plus of the spot measurement is precisely indicated by the selected fragment. This works especially well when contrasting objects are captured in the photo. Also in situations where the selected fragment is highly illuminated and the background image is in the shade or vice versa.
This type of minus in the ability to lose the entire frame, except for the selected object. The rest could be too bright or vice versa dark.
When to use spot measurements
Fans seldom use it. And experts know that in many situations you can not do without it. For example, removing a person in control lighting requires you to choose the point exhibit precisely. Otherwise, the person is just a dark silhouette against a brightly lit background. Also, point measurements are useful during macro shoots (when the object does not occupy the entire photo area) and while photographing a person or object at a considerable distance.
This type excels in uniform illumination of a photograph, despite the fact that the object itself is darker or brighter than anyone else in the frame. Thus, point-of-view exploration is perfectly addressed when shooting white pigeons with a camera against a black wall background, or a black girl against a light background.
Camera matrix test
Unlike the point mode, matrix measurements are performed in several zones of the frame at once, determined by the camera itself. This method derives an average value in terms of the ratio of light to shadow as well as the brightness of all selected fragments. This is how the description of the entire frame is determined.
The algorithm by which matrix exposure works is very complex and is individual among the various manufacturers, keeping them in the dark. Depending on the manufacturer, the picture is divided into a specific number of zones. From tens to thousands.
By measuring the exposure, the camera analyzes not only the lighting, but also concentrates points, colors and the distance from the object to the camera.
In favor of the пользоватьсяматрич pathetic, etc.
This type is most popular among photographers. It is not relevant for lovers or professionals. It is especially useful in the uniform illumination of a scene.
Its plus is universality. If you do not know which mode is better to choose, or if you do not have enough time to analyze future frames, it is better to install Matrix Exosparmer.
Centralized system
This type is based on the analysis of 60 to 80% of the frames. The measurement zone has a circular shape and is centered. Now we have a model that allows us to adjust the size of this zone. The edges of the picture only slightly affect the display of the frame.
Some time ago, the center specialist was the main focus of most cameras. Now he remains as such in compact cameras and has been replaced by a matrix in the mirror in automatic mode.
That plus the main object to be exhibited. After all, as a rule, they are near the center and not at the very edge of the picture.
When to use the central explorer
This is ideal for portrait shooters. If the main object is a person, it is more important to execute properly than the surrounding objects or background. The central specialist is more predictable than the matrix. Thanks to him, the camera can rule out the influence of the rear of the picture on the model’s portrait. It is good for shooting people on bright sunny days. When using focused measurement, a preliminary focus function helps. It can block the exposed person during the period while the trigger button is half pressed. Therefore, consider an explanation by centering the object, shifting the frame to the proper location, and then pressing the shutter button fully.
Which exosparmer is best suited for shooting
This question is asked by many newcomers who decide to master the camera successfully. However, there is no clear answer. After all, it all depends on the task and conditions of the shoot. The easiest way is to use the matrix or intensive mode. In most situations, they show the frame correctly. They are more universal. At the same time, proper lighting objects in contrast to the background are best removed in the matrix test mates. Contrast – in the center. Also, for more non-standard shots, such as control light portraits, point measurements are suitable.
Exposition compensation – best results
All types of exhibitors take only reflected light into account, which can lead to errors in frame exposition. In this case, exposure compensation should be used. A standard example is a winter landscape of a snowy forest against a white sand background on a sunny day. They will likely not be integrated. A 1-2 step exposition compensation fixes the situation and takes pictures.
Determining exposure is a complex process. At first it is very possible to trust the basic settings of the camera. However, the curious itive thriving to develop in the field of photography should be able to handle the examiner, choose the type needed, and take pictures not only in standard but also in more difficult situations. The camera can not always determine the exposition correctly and should be able to help it with this. With experience, this is not difficult to reach automation and accurately determine the desired regime. Give it a try!
