I (and many photographers) routinely aim my spotmeter at the palm of my hand and then open up one stop to get a meter reading. There's no reason why the M6 meter can't do something similar. All that need to be done is have the meter calibrated properly. Hmm....actually, many photographer don't aim my spotmeter at my hand, only I do that. They use their own hands! And they use their own spotmeters! Dan C. At 09:24 AM 24-08-00 -0700, Dan Post wrote: >Dan ( The other, really crazy one!)
