Is sharpness important for a good photo? Yes and no. On the one hand, technically perfect photography, as a rule, should be absolutely sharp. No matter how entertaining it may be in artistic terms, the fuzziness of plot-significant elements will make it suitable only for an amateur photo album. On the other hand, if a photograph is technically perfect, but devoid of artistic or at least protocol value, then it is generally unsuitable for anything. In other words: sharpness is important, but you should think about it only when the lighting, composition and other fundamental aspects of photography do not cause you any Continue reading
Depth of sharply depicted space (depth of field) is the distance between the closest and farthest object in the scene, which are perceived in the photo as sharp. Everything that lies closer or further than the depth of field zone is more or less blurred.
It should be understood that the concept of IPIG is quite arbitrary. There is no real and unambiguous depth of field in nature, since the lens at a time can be focused only on one specific distance, and not on some abstract range of distances. It is more appropriate to speak more about a focusing plane of infinitely small thickness, closer and further which the image begins to blur. Continue reading
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
