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

Depth of field
Depth of sharply depicted space (depth of field) is the distance between the closest and farthest object in the scene, which are perceived in the photo as sharp. Everything that…

Scatter Circle Size
A scatter spot (circle) is a distorted image of a point projected by a photographic lens onto the camera’s matrix or film. These distortions are caused, firstly, by structural factors,…
