Good evening, I've just purchased a used 'Minolta M' spot meter from a photo swap meet and will be using it with my medium format. I think the use of the meter for landscape photos (Zone System, sorta) is understood. However, the method of use for available light portraits is not clear. What part of the face do I meter off of, or do I meter off of my hand? Also, can anyone describe the functions of the not so obvious controls? I'll find a manual eventually, until then......(posted 9066 days ago)Thanks for any input, Bob Passage
