Skip,
Let's say I'm taking a picture of a very dark subject (e.g. the side of a black
camera lens) to sell on eBay. If an exposure of it yields very dark tones, then
the buyer cannot see detail on the lens body. So instead I want the object to
appear in tones of gray. Based on an incident flash reading at the subject, I
would probably need to open up a stop or two from that.
I admit I am not experienced in this domain. I have only recently acquired a
Minolta IV F, with incident and 5 degree reflectance attachments.
