fill light source size vs main light size
jpc wrote in message ...

Main light is a spot which casts hard shadows. Fill light is a diffuse light source that fills and breaks up the shadows. For the classic look I use a direct flash as a main light and a flash with a reflecting umbrella behind the camera as a fill . But play around. And the perfect model for your testing is a big doll head--bratz or the like. They never become bored and complain. Ain't it the truth... Real kids get bored REALLY fast when it's time to set up lighting... As for the flash configuration, the fill doesn't effect the picture as much as the key light. With either box in front of the subject, you should get a nice even lighting which won't throw any shadows, so your shaded areas will look good. When it comes to the main, or key, light, you can really bring out your subjects best features by moving the softbox around. Try changing both the distance from the subject as well as the angle the light is offset from the camera / subject axis. Placing the light at about a 45 degree offset will give you a more traditional look, while moving it to about 90 degrees can give you a much more dramatic side-lit effect. Also, if you can get some height on the key, your pics will probably look a bit better. One thing you didn't mention is whether you will use a third flash to give your background a graduated appearance. If possible, try to put a third, smaller flash, behind the subject directed so that the brightest part of the light is down behind the subject, not really visible. Then, as the eye moves up the backdrop, it gradually gets darker. This can help add some separation to the image -- helping the subject to appear more naturally situated. Lastly, try varying the lighting ratio, which is to say, setting the output of the key to twice the power of the fill yields a 2:1 ratio; if it is three times as bright, the ratio will be 3:1. Using a variety of ratios such as 3:2, 4:3, etc will also add some life to the image. Good Luck, Dudley |
