I am fairly new to photo.net and am having a mental block understanding the originality rating. It seems a photo is either not original (a typical stand up straight and smile at the camera photo) which would rate a 4 (average), or it would differ in some manner that adds originality making it deserving a rating of 5, 6 or 7. My question is how can a photo's originality be less than "not original" (a 4 rating)? It seems a originality rating of 1, 2 or 3 makes no sense unless one rates the stand up straight and smile photo is a 1 (very bad). What is very bad originality, something that is not original? Insight into equitably rating originality is appreciated.
