Digital Cameras Image File Formats
There are three types of digital camera file formats:
The most commonly used format, JPEG, is often the only one available on entry-level and some intermediate digicams. Not to worry, this format is perfectly fine for the vast majority of digital camera users. Almost every photo uploaded to the Digicamhelp website was shot as a JPEG.
Many higher-end digicams allow you to select between JPEG, TIFF and RAW. Professional photographers and serious photo-enthusiasts usually prefer to shot RAW. Some advance digital cameras has a setting to shoot RAW + JPEG simultaneously as separate files.
