Convertisseur Gratuit en Ligne PEF vers G4

This format is used to create RAW photos on Pentax cameras. It stores the full set of data obtained by the camera's sensors during a shoot. It allows you to fine-tune lighting, shadow, and exposure parameters while retaining all the details and the original quality of the photo.

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).
