Mark A. Rapp Posted March 3, 2007 Share Posted March 3, 2007 Question: When taking multiple light readings on set, when averaging the readings, should one average the number readings as a regular average? Example: 2.8 + 5.6 = 8.4 8.4/2 = 4.2 So the setting is 4.2? Or is there another formula for this type of averaging? Link to comment Share on other sites More sharing options...

I don't average readings, I decide how I want the shot to look like and expose acording to that. The question is how much under or over Key do I want a light to be.

Wow...anyway Yeah, you don't want to just set your aperture to what's average for all the readings you get. Decide what you want at key, under and over, then set your f-stop accordingly. Or better yet, as I do, decide on an f-stop beforehand and meter everything according to that. Link to comment Share on other sites More sharing options...
