Nikon Autofocus Speedlight SB-24 - Manual (Page 65)

FLASH EXPOSURE COMPENSATION
Varying the amount of flash, in relation to the available-light exposure, creates different
fill-flash effects. We say the fill-flash effect Is balanced when the flash Illumination is
sufficient to brighten the subject to “almost” the brightness of the background. Some­
times we want to use a little more or less flash to make the subject a little brighter or
not quite so bright. Your choice may be based on desired esthetic qualities, or may be
forced by extremes in lighting.
Generally speaking, you don't want to make the subject too bright, you just want to
brighten shadows. To achieve a subtle fill-flash effecf, you may wanf to use some
manually selected “minus" compensation. However, when the background is ex­
tremely bright, and the subject is in deep shadows, you will probably want to use some
"plus" compensation. While the SB-24 is quite powerful, whenever using it for fill-flash,
it is competing with the sun’s brightness—very strong competition.
With standard TTL flash (with E3 blinking) you can manually compensate exposure by
adjusting flash output level. You can also adjust flash oufput level for Matrix Balanced
Fill-Flash or Center-Weighted Fill-Flash, in combination with the computer’s automatic
compensation.
