Ever had a thought of something you SHOULD have done when trying to get a shot? Something simple that maybe could be passed along that could help others?
One big one for me ... DO NOT say "I'll come back later and get that shot". When you see a scene worth shooting, TAKE THE SHOT NOW!!!
I have a tendency of doing this all the time and always regret it because for any number of reasons, what I see "now" is not the same and usually completely different "then".
