RAW or JPEG?

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

Image angle

The angle of the image or the angular field of the lens is the angle formed by the rays connecting the extreme opposite points of the frame with the optical center of the lens. In other words, this is the maximum angular size of an object that can be captured using this lens.

The wide angle of the image allows the lens to cover more space due to the small scale of the image. The narrow angle of the image shows less space, but on a larger scale.

Since the frame has a rectangular shape, it is necessary to distinguish the angular field, measured horizontally, vertically and diagonally. In the technical characteristics of photographic lenses, the largest, i.e. Continue reading
