Re: High Key Imaging
Bill,
I thought the subject is always the subject that you trying to take the picture of. Background is background. If you are taking a picture of the background, then I would call it the subject. If you read the tutorial, it says, measure your bg light at the cheek of your subject facing towards the bg and it should be 2/3 stops higher than what's falling on the subject. It says, don't worry how much light is falling on the bg.
Shouldn't we be measuring incident light on the bg and keep it say 1 stop higher than what's falling on the subject in this case? Like in the case mentioned, if f10/f11 on the bg and subject is f8, it should give you nice white bg. Now if you move the subject say 5 feet towards the camera and if you still keep f8 on the subject, the bg should still be white as light falling on it hasn't changed.
If instead, I measure f10/f11 at subject location, facing the bg, as I change the subject distance by 5 feet, I will have to really crank the bg light power due to inverse sqaure law. That's what I didn't understand in Benji's explanation.
