How does a digital camera work?

For full control over the process of obtaining a digital image, it is necessary, at least in general terms, to imagine the device and the principle of operation of a digital camera.

The only fundamental difference between a digital camera and a film camera is the nature of the photosensitive material used in them. If in a film camera this is a film, then in a digital one – a photosensitive matrix. And just as the traditional photographic process is inseparable from the properties of the film, so the digital photoprocess largely depends on how the matrix converts the light focused on it by the lens into a digital code.

The principle of the photomatrix
The photosensitive matrix or photosensor is an integrated microcircuit (in other words, a silicon wafer), Continue reading

Exposure: Theory

A good exposure is critical for quality photography. However, the essence of the exposure is extremely simple. Exposure is just the amount of light entering the photosensor. The process of shooting a frame is sometimes called exposure.
Exposure can be reduced, but can be increased. That, in fact, is all that you can influence. A smaller exposure makes the frame darker, a larger exposure makes it brighter. The lack of exposure is called underexposure, excess – overexposure.

Exposure is measured in exposure numbers or exposure levels (EV – exposure value). Changing the exposure by one step means changing the illumination of the frame by half. Continue reading

Camera modes

Today, any digital camera offers the photographer a frightening variety of shooting modes. Due to the fact that the instructions for the cameras describe the features and purpose of a particular mode is very vague, it is difficult for a novice amateur photographer to determine which modes are really useful and which are marketing nonsense. As a result, many either spit on everything and shoot exclusively in AUTO mode, without trying to dig deeper, or, believing the authors of the instructions, try to use narrow-minded scene modes (Portrait, Landscape, Sports, Macro, etc.), without suspecting that with a minimum of mental effort, you can achieve much more flexible and complete control over the camera without any harm to your own comfort.

Understanding the modes of a digital camera is the simplest thing that you, as a photographer, should learn. If you are familiar with the concepts of shutter speed and aperture, then it will not be difficult for you to deal with shooting modes. Continue reading
