it's your own eye...;)It's a military-type name for it...;)

I use backgrounds all the time...I usually try to remember the intensity, color, and direction of the lights (I usually use Bryce), and when time comes, to use the Poser lights with roughly the same settings.

Also, in some cases, I'll try to use fainter lights as 'reflected' light; for example, maybe sort of a grayish light coming off metal, or brownish off wood, and blueish (is that a word?...;) off the sky, depending on the scene.

Hope that helps.
