I am aware of most of the different metering except a few. Im not sure of what they all do. I know alot of what they do but i want to know when and how to use them. some help? I am ashamed i do not know this when i am as talented as i am. Could someone explain how to spot meter and how to actually physical do it. where do you focus etc? I see photogs focusing on the ground or something then back at the subject to meter the exposure how does this weird thing work ? thanks? i
