Definition needed on photos
 

There was a thread not long ago (cannot find it now) which defined type 1,2,3,4,5 photos.
Can someone post that again please?
Thanks.

found this in the "question for my education" entry. It's a link to the definition and you need to go all the way to the bottom of the page to find it
