Patience helps a lot as well. Be prepared to take tons of shots before you get a really good one, and just keep practicing. My King Snake is the hardest thing to get a shot of, so I take pictures of him when he's feeding or the day after he feeds (without moving him), because he's a little sluggish for a while. I've also found it's easier to get my BPs during the day, when they wouldn't be so active, although I'm sure they don't like to be woken up, hahaha
