How to find out the pixel size of a matrix?

Why might a photographer need a pixel size? There are enough such situations. Knowing the pixel size can be useful for determining safe shutter speeds when shooting with handhelds, because the smaller the pixel, the more noticeable the camera shake appears in the pictures, and the shorter shutter speed may be needed to eliminate movement. Having no idea about the pixel size of the matrix of your camera, you can not seriously talk about the depth of field, since the allowable diameter of the scattering circle directly depends on the size of the pixel. The value of the diffraction-limited aperture for a particular camera also depends on the pixel size. Finally, it is possible that when comparing multiple cameras, you will want to find out which one has a higher pixel density, which means it provides better detail and is more suitable for shooting distant objects.

The instructions for digital cameras very rarely indicate the pixel size of the matrix, but, fortunately, this parameter is quite easy to calculate on your own.

In most instructions, you can find information about the physical size of the photomatrix, as well as its linear resolution, Continue reading

Optimum Aperture Selection

The ability to effectively use an existing lens has a much greater effect on the sharpness of a photograph than the choice of the lens itself. The number of apertures is the most important of the shooting parameters that affect the technical quality of the image. The difference between different aperture values ​​of the same lens can be much more noticeable than the difference between different lenses with the same aperture.

Obviously, for the standard fast lens used in this test, sharpness is ideal at f / 5.6 aperture, but f / 4 is Continue reading

Composition

Composition is the most important aspect of art photography. Composition is the art of arranging the various elements of the image in the most harmonious manner that meets the creative intent of the author and allows him to fully convey his thoughts and feelings to the viewer.
The gaze of a person looking at a scene moves far from randomly. First of all, he seeks to cover the most significant elements that attract his attention, in decreasing order of their attractiveness, then he goes around the entire available field of vision, assessing the relationship between important objects, and practically without stopping on insignificant trifles, after which he returns to the semantic center. This Continue reading
