Light probe

This is what the light probe looks like. It's a photo I took of a chrome ball which has been distorted in a way that my rendering software (mental ray) understands. The final one I used was a combination of mutliple exposures and multiple angles to remove me and the camera tripod from the picture.
I'll use it for both the lighting and the environmental reflections (off of window, for example) in the 3D scene.
