Autofocus or autofocus for most photographic scenes is the preferred solution over manual focus. In skilled hands, autofocus focuses more precisely, and, most importantly, faster than the average photographer. However, autofocus is far from being as simple as it might seem to a novice amateur photographer, and its proper use is very far from the point-and-shoot principle. There are a number of subtleties that you should learn if you want autofocus to stop living its own life and begin to do what you want from it.

The electrical signal generated at the time of shooting by the matrix of a digital camera enters the camera processor as an array of digitized, but not yet processed or, if you like, “raw” data. This data is then either recorded without further processing on a memory card in the form of a so-called. RAW-file, or pre-processed by the camera processor, which forms a full-fledged image on their basis and saves it in JPEG format. JPEG photos are the final product of the photographic process and are fully suitable for viewing, printing, publishing on the Internet or any other practical needs. Pictures saved as RAW files must be edited in a special converter program, which allows you to convert raw data provided by the matrix into a graphic image in JPEG or TIFF format. Shooting in RAW is used in cases where the photographer for one Continue reading
