As long as there's no attempt to deceive the court. In my example in the murder trial, the only thing changed that made the evidence bogus was the resolution of the video. There was no cloning, parts removed, or any other changes made from the original video except resolution. Yet that was enough to fool the court, at first, and almost convict an innocent man.
While most photos and videos don't rise to this level of importance, journalistic news photos, commercial photos, and videos, change public opinions and sell products and ideas often due to deceptions of photos and print. It's an important issue. Currently I've checked photos of what my vacation hotel rooms will look like in Paris and London when we visit soon. I hope we're getting that large King size bed they show in the pictures and not a cot.
