Format introduction | A camera raw image file contains minimally processed data from the image sensor of either a digital camera, image scanner, or motion picture film scanner. Raw files are named so because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor. | The Graphics Interchange Format (better known by its acronym GIF) is a bitmap image format that was introduced by CompuServe in 1987 and has since come into widespread usage on the World Wide Web due to its wide support and portability. |
Technical details | Raw files contain the information required to produce a viewable image from the camera's sensor data. The structure of raw files often follows a common pattern: a short file header, camera sensor metadata, an image thumbnail and the sensor image data etc, | GIF supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space. GIF images are compressed using the Lempel-Ziv-Welch (LZW) lossless data compression technique to reduce the file size without degrading the visual quality. |
File extension | .3fr, .ari, .arw, .bay, .crw, .cr2, .cap, .dcs, .dcr, .dng, .drf, .eip, .erf, .fff, .iiq, .k25, .kdc | .gif |
