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…

When all else fails

Are you still unhappy with the sharpness of your images? Isn’t it too much you want?

A digital camera is basically not capable of providing absolute sharpness. Most photo sensors are equipped with a special anti-aliasing filter that slightly blurs the image so that any point of the original scene in all cases is perceived by more than one photodiode. This is called antialiasing (antialiasing) or smoothing and is necessary to prevent moiré-striped artifacts that can occur when photographing fabrics and other items that have a periodic, repetitive structure.

Shutter speed or, as it is also called, shutter speed is directly related to the transmission of motion in images. When shooting still subjects with a fixed camera, the shutter speed does not matter and is determined only by the required exposure. But when either the camera or the subject is in motion, choosing the appropriate shutter speed becomes not only a technical but also an artistic task.

Not to get confused: the higher the shutter speed, the shorter the exposure time than a shutter speed lower the shutter speed longer. Continue reading

Functions and actions of the camera processor
The camera processor is an electronic element that controls all its available functions and, in addition, provides pre-processing of the image. Thus, we can say that the processor is nothing…
