I was just curious to get opinions on what photographers tend to overlook when either taking or editing a shot in post? I'm far from being a professional but one thing I seem to always notice instantly when photographers post photos on facebook and sites like that is if horizontal lines in the photo are actually horizontal. Example might be the horizon or maybe if a model is sitting on some stairs and they are tilted at an angel. I know there are times when these things are done on purpose for effect, but most of the time it completely turns me off to a photo.
What others do you have? I'm sure there's going to be loads that everyone could probably learn from.
