Steve 21 has an interesting trick for finding good available light: he places a marble in his hand to simulate what the light would look like on a human face:
Just hold a fist in front of you (like holding a telescope), tuck the marble just under your forefinger, and there you have it – the same lighting an eye would get.
And since you know you want the catchlights to be up at 1 to 2 o’clock, or up high at 12 o’clock, simply turn about until you see the catchlights you want.
The neat thing is that the curves and wrinkles of your hand show you the amount of contrast and backlight.
Black marbles: the latest must-have item in any beginning photographer’s camera bag.
