I want to wring their neck and say, "Then don't take the bloody picture -- or at least don't print the dang thing!" But I don't because I actually know what they are trying to say and we all have to make these errors and hopefully learn from them.
And what if the original photographer says: "I like it that way. That's why I took the photo."
Who are you to decide that the pic contains an "error"? Are you the final arbiter of artistic vision on this planet?
