The tone of a photographic image is determined by the proportions in which black, white, and gray tones are correlated.
Degrees of tonality in photography
The human eye recognizes up to three hundred steps between white and black. In a black-and-white image, there can be up to thirty tones (long tonal scale) or up to ten tonal shades (short scale).
Moderation in the number of tones sometimes provides a photo with greater expressiveness. By eliminating the middle tones, you will get rid of non-essential elements, and photos taken in a certain key will turn out to be very effective.

Human vision is binocular, which means that we have an excellent perception of the shape and volume of objects in space, regardless of the light.
But in photography, everything is different: it is two-dimensional, flat, completely dependent on light, which often distorts the shape and volume of individual elements.
The optimal ratio of shadow and light will help add volume to the photo, provide the effect of three-dimensional space, mark the texture, and give the image the appropriate mood and emotions.
Adding volume to a photo Continue reading
