Most passionate photographers like to carefully control all kinds of details related to their photos — from adjusting colours and lights, to correcting red eyes or cropping. And for this reason, they prefer setting their camera to take pictures in RAW format. Also known as “digital negatives”, RAW image files have the great advantage of allowing a wide array of computer editing options.
If you like to take your quality photos with a Fujifilm camera and have just got the new X-E1 model, for example — you will soon discover your RAW image files have the RAF extension. This is the typical format for all Fujifilm cameras, and while generally preferred by photographers, it might prove difficult to handle at first. Why? Because RAF files are not recognized by many regular photo viewers, so you may have problems opening and editing them. Moreover, they have a very large size (up to 6 times more than a JPEG), so sending or moving a large group of photos might prove to be equally difficult.
