Imagine you are inside a dark, old church. You are trying to get the whole place and right in the upper center you are facing a stained glass window lit by the strong outside light. What would be your settings to get everything properly exposed? Spot meter on the window adjusting exposure settings in M mode? Any other suggestions? I will use the D200 on tripod and either a 28 f/2.8 or 10-20 SIGMA. Thanks in advance for your help.
