Im a photography student and on of my questions is to do a greycard test to build a zone ruler. I have done this multiple times and getting frustrated. Can or will anyone walk me through this? what is the best lighting for this? how do I get 13 shots for dynamic range using full stops? I dont want you to do my homework just simplify for me if you can or will.
Please and thank you
christy
