The area (basement) where my tree frogs are becomes pitch black after lights out. I even have the windows covered. I use a tiny regular flashlight ( not a laser !! ) when I want to view them. I got 3 of these at Home Depot - they use a AA battery. This little light can be pointed near the frog, not right in it's face of course. It's a small enough light not to put them right back to sleep.

Most of the photos in my albums were taken at night ( w/ an iPhone only - 3GS- no flash) . I have the most ridiculous head gear for photos. I taped one of the small flash lights to a headband; this way both my hands are free for a photo op. The things we do !!!
