A histogram is a chart based on the tonal distribution of pixels in a picture.
From the left to the right (horizontally) the brightness is indicated, and from the bottom up (vertically) the amount of the photo area of a particular tonality. It is often said that vertical columns simply show the ratios of the number of pixels of a particular pitch. That is, the diagram shows how much light or dark shades prevail in the picture, how many green or red or other shades of colors in the picture are larger. Histograms are different. In photography, basically, three types are used: Continue reading

Previously, most photographers were shooting on film cameras, which used the so-called 35mm film (standard film from the distant 1930s). These were quite old times, and somewhere since 2000, digital mirror cameras (CCP) became very popular, the principle of operation of which remained the same as in film cameras, but instead of CCP film they began to use an electronic photosensitive matrix, which forms the image .
