LOL isn't it annoying when snakes just can't sit still for just 5 seconds?
Also if you do get some really good photos, I recommend trying out GIMP. I downloaded it off of a website (it'll pop up if you just type in GIMP on Google or whatever search engine you use) and I use it to level out the White Balance for all of my photos I take with my camera.
It truly does make a huge difference if the White Balance on your camera is a bit off or the lighting in the room changed the White Balance of the photo. I could post some pics for an example if you'd like of a before and after. I'm also going to take new photos of everything in the reptile room this week so I'm definitely using GIMP to White Balance the photos.
