|Light Painting with Frogs (Agalychnis callidryas) - Selva Verde, Costa Rica|
Canon 7D + Canon 100-400L IS @ 400mm
Exposure: ISO 200 : 6 seconds : f5.6
While traveling through the tropics this July, we had the opportunity to do some light painting. Unlike the millisecond pop of a flash-trap, light painting relies on long exposures to soft light. To paint with light, you’ll need a friend or two to illuminate your nocturnal subject. To emulate the appearance of candle or firelight, we covered the bulbs of our dying flashlights with our hands and slowly moved the light near and around the frog. This type of light painting requires you to prefocus, and bump your iso to 400 or 800. I suggest that you use a stable tripod, mirror lock-up and a cable release in order to minimize camera movement. You’ll need to be prepared to experiment with duration of your shutter, take many pictures and stay up late!
