The fight against laziness and time management for the photographer
Let's not forget that many photographers are now giving their clients photographs in indecently long periods. I will not quote wedding clerks who give out albums after 9 months, when…

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…

Starry sky

Many people who admire the starry sky on a clear night have a desire to photograph the sight they saw. Unfortunately, these attempts are far from always crowned with success, especially since a person who is accustomed to photographing exclusively during the day with an excess of light is often unclear on which side to approach the shooting in such seemingly unfavorable conditions. Nevertheless, to get a beautiful night shot with saturated colors, clearly visible constellations and a whitish strip of the Milky Way crossing the sky is easier than it might seem at first, and in this article I will try to make it possible to highlight the practical side of the issue. I note that we will not focus on high astrophotography, but rather on ordinary shooting of the starry sky in the context of landscape photography. Detailed shooting of deep space objects (galaxies, nebulae, quasars, etc.) requires very specific skills and tools, while decorating the night landscape with the general plan of the Milky Way is possible for everyone.

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

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, i.e. natural imperfection of optics and photosensitive material, and secondly, functional reasons, and above all – selective focus. An image of an infinitely small point can be a point only when it lies strictly in the plane of the matrix or film. If the image of the point is out of focus, the point turns into a blurry spot of rounded shape, the size of which increases with distance from the plane of the ideal focus (see also “Bokeh”).

Diffraction
Diffraction is an optical phenomenon that limits the sharpness of a photograph while reducing the relative aperture of the lens. Unlike other optical aberrations, diffraction is fundamentally unremovable, universal and…
