Hi Linda,

I have found that while it matters a great deal in taking slides, the
exposure not as critical with digital photos. Slight adjustments are
easy with software. Also you are getting instant results, which makes
it easy to make minor adjustments in lighting, etc.

It is common for slide shooters to "bracket", that is, to shoot a stop
higher and one lower than what the meter is telling you. Or some even
do half stop increments. I have found that if I use the meter in my
old Nikon FM for one shot and then one with what the handheld spot
meter says (sometimes it's the same, but more often not), I will get an
exposure I like between the two.

But to answer your question: I don't know.

Really I think this is a question about printers. A good look at what
your camera is doing can be had by looking at the histogram in
photoshop or on your camera. The values represented by the histogram
should spread out all the way from white to black but just barely touch
the white edge or black edge. If you are getting exposures without
whites/ or blacks/ or your exposure bunches up on one side of the
histogram either your subject is too contrasty for the lattitude of
your camera or your exposure is wrong. If its all bunched in the middle
your lighting is not contrasty enough. Once the digital exposure is
good it gives you choice in how your print or publish it. Used to
teach this stuff before there were experts. Now I know more and run
scared.
