In my experience no word is misspelled more often in the photography world than the name of an unprocessed photo file. Some people spell this unprocessed file RAW, assuming that it is an abbreviation for something – but in fact it isn’t. These files are unprocessed, that is, they are uncooked, or raw.

On the other hand, JPEG is an abbreviation – for Joint Photographic Experts Group. A compressed file using the JPEG compression algorithm is a JPEG file. If you look back far enough on my blog you will see that I didn’t know that it should be capitalized – so you’re not alone.

I agree that it’s not a big deal either way, but now you know!
