We talked about exposure meters last night. I've always called them light meters - but I stand corrected by my instructor.

The only real tidbit of information I pulled from last night's class is to compensate the exposure on your camera when shooting either very dark, or very light subjects. I always knew this -- and I do a fairly good job with it -- but I never really knew just how many stops of light I should compensate so the image will turn out the way my eye originally saw it. Answer: 2 stops of light. If it's a really white subject - add 2 stops -- if it's a really dark subject - subtract 2 stops. You can do this by either adjusting your shutter speed or aperture.

Now you know what to do when making images of Polar Bears and black cats...
