Convertisseur Gratuit en Ligne SR2 vers G4

This digital photo format was created by Sony. It is stored with a RAW-file structure. It contains a wider range of data than a compressed photo. It records the maximum amount of information obtained from the camera's optics and sensors. This gives the photographer more freedom to process and edit photos without loss of detail and image quality.

G4 is a method to compress black and white images without losing quality. It is used for fax machines and as a one of the compression types for the TIFF format. G4 treats a picture as black dots and lines on a white page (less file size will be achieved if there are less black dots and lines).
