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…

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,…

How to use autofocus

Autofocus or autofocus for most photographic scenes is the preferred solution over manual focus. In skilled hands, autofocus focuses more precisely, and, most importantly, faster than the average photographer. However, autofocus is far from being as simple as it might seem to a novice amateur photographer, and its proper use is very far from the point-and-shoot principle. There are a number of subtleties that you should learn if you want autofocus to stop living its own life and begin to do what you want from it.

I highly recommend that you re-read that section of the manual for your camera that focuses on autofocus – these are some of the most useful pages in the entire manual, and the information contained therein should not be neglected. At a minimum, you should be aware of which controls are responsible for switching between different autofocus modes and choosing the focus point you need. Continue reading

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.

Capacity

The bit depth or color depth of a digital image is the number of binary bits (bits) used to encode the color of a single pixel.

It is necessary to distinguish between the terms bit per channel (bpc – bits per channel) and bit per pixel (bpp – bits per pixel). The bit depth for each of the individual color channels is measured in bits per channel, while the sum of the bits of all channels is expressed in bits per pixel. For example, an image in the Truecolor palette has a resolution of 8 bits per channel, which is equivalent to 24 bits per pixel, because the color of each pixel is described by three color channels: red, green and blue (RGB model).
