Light
Light is the heart of photography. The camera does not see the image. There are no lines, shapes, or textures for it. A film or digital sensor is only susceptible…

Adding volume to a photo
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…

Features of color correction in Photoshop
The work of the color corrector mainly consists in processing images (and other material) that are being prepared for output to devices. Often, processing causes a lot of problems for…

Dynamic range

Light falling on the photodiodes of the digital camera matrix is converted into an electrical signal. For this to happen, the number of photons that hit each individual photodiode must exceed the sensor sensitivity threshold. If there are not enough photons, the corresponding section of the frame will be completely black. If the exposure is excessive, the photodiodes are saturated with photons and the overexposed area turns out to be white. The ratio between the exposure values required to produce a completely black and completely white color is called the sensor’s dynamic range or photographic latitude. Continue reading

The strategy for choosing the optimum diaphragm
Find the aperture value at which your lens shows the best sharpness, and use this value whenever possible (most often it is f/8 or so). If you don't have enough…

Tonal range values
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…
