Just purchased a Mamiya RB 67 Pro S as my start into medium format photography!!
very excited to play around with it when i get in about 5 or so days.
Though it is fully manual , just wondering if someone can help me with estimating proper ?
As i understand , i should use the rule, which is,
100 at f16 is 1/100 (or 1/125)
then if it becomes slightly overcast it would turn out to be...
100 at f11 at 1/200 (or 1/250)
overcast would be
100 at f8 at 1/400 (or 1/500)
would this be right or am i completely left field?
