ORF is a highly specialized raster image format. Created by Olympus camera manufacturer to store digital images taken by these devices. The name is an abbreviation for Olympus RAW File. ORF files are sometimes referred to as digital negatives. In this format, digital data from the camera sensor is stored in its original form, in excellent quality (the highest possible) and without distortion. Image storage is in its raw form. Editing an ORF file is only possible if it is converted to another format.
GIF is one of the most common raster image formats. Its name is an abbreviation for Graphics Interchange Format File. The developer is the CompuServe organization. A feature of this particular image format is its ability to support the animation function. You can edit animated GIFs in different programs (for example, Easy GIF Animator). Animation is achieved due to the fact that a file of this format carries in itself in a certain sequence several raster images at once. With a depth of up to 256 colors, significant data compression in GIF files is possible without loss of quality.
