In the photography world it's shorthand for "photo unedited straight from the camera". Popular with Fujifilm cameras especially due to their 'film simulation' modes which apply basically a filter to the image.

Not really? Unedited would be some sort of raw. JPEG usually implies preprocessed by the camera

		I guess I meant unedited by the photographer manually (e.g. using Lightroom etc.) Either that or a photo that has been edited from a RAW and is a final version to be posted online.
