Hello again, I had a subject that was standing in front of a window. I wanted to test the matrix metering and took the picture without compensation in program mode. The subject came out underexposed. I took another with flash fill that came out fine. Is this normal or is this a metering problem? I was wondering if the technology in the N80 could be fooled like that.
You're testing by doing something you're not supposed to do?
Backlighting will cause that problem even with an F5... You should be using fill-flash. If you find your fill flash too harsh, dial in -1.7 FLASH compensation - voila - perfect flash-fill.
The reason this happens is because the matrix meter assumes you'll use fill-flash for backlit scenes, and underexposes accordingly to balance for the flash exposure.
Think of it this way: If light is hitting the back of the object you want to photograph, you've got to have a way to bounce it back toward what you want to photograph or you'll be photographing a shadow..
I'd hazard a guess that with the centre-weighted metering of the F100, the main subject will still be underexposed... Not wanting to use flash requires one use a spot meter in these situations - hence sacrificing the exposure of the background.
