Inverse square law
It is not superfluous to mention here also the law of inverse squares, the action of which you will certainly encounter. It sounds like this: the intensity of light is…

Exposure settings in limited lighting conditions
Everyone knows that in order to get a good picture, you need the right lighting. However, photographers often have to work in not the most comfortable conditions, when there is…

Exposition. The exposure compensation
Exposure is the amount of light needed to create a photo. Nothing complicated. The exposure is dosed with fixed assets: Extract Aperture ISO sensitivity value Flash (or other lighting devices)…

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

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…

Geographical latitude
I am writing this in the most temperate climate, being in the fifty-fourth degree of North latitude. In the southern regions, the light changes much faster, both in the morning…
