Subject: RE: Fill flash
Richard,
A question: What is the white handerkchief trick?
And some input: Some modern cameras also decide on when to use the flash as
a main light source, or for fill, according to the ambient light levels.
Regards, Veli Izzet
Hi Marilyn:
The basic principle of fill flash is to set your exposure in the camera for the ambient light, taking care to use a shutter speed that will sync with the flash. Then you adjust the OUTPUT of the flash to give you the amount of fill you want. The operative word here is "output". This is the way I explain it to my students.
If it's a modern camera and a dedicated flash, you can accomplish that via the Flash Compensation feature on the camera. If it's an older non-dedicated model, like the Vivitar 283, you can put the flash in Auto and select a mode that is one or two stops wider than what the camera lens is actually set at, as you mentioned. I did this for years when I was a PJ. However, I don't think this latter procedure will work with a dedicated flash.
The white handkerchief trick works well as long as the flash is not in some auto mode. On some flashes, you can set the ISO one or two stops higher that what the camera is functioning at.
I'm sure you know all this, Marilyn, but I know from experience that strobe usage is one of the most difficult things for students to comprehend. My approach is to concentrate on a simple "how-to" procedure; less on theory. Good luck!
Richard
