Selecting the optimal aperture

The ability to effectively use an existing lens has a much greater impact on the sharpness of the photo than the choice of the lens itself. The aperture number is the most important of the shooting parameters that affect the technical quality of the image. The difference between different aperture values of the same lens may be much more noticeable than the difference between different lenses at the same aperture.

Aperture f / 1.8 f/1.8
Aperture f/2.8 f/2.8
Aperture f/4 f/4 Continue reading

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

Color balance

The colors of objects that we see are not a property of the objects themselves, but a property of our vision. Grass looks green only because light rays reflected from it with a wavelength in the range of 500-565 nm, falling on the light-sensitive receptors of the eye, cause the brain to feel green. Having got used to the fact that the grass is usually green, we see it green even in unusual lighting. Human vision is characterized by color impermanence. Our brain adjusts the color balance so that objects retain their natural colors for us as much as possible, regardless of the color of the lighting. White paper seems to us equally white, that in the daytime, when it is illuminated by cold light pouring from the window, that in the evening, when the warm light of incandescent lamps falls on it.
