metering mode

Just to add on point.

Does 18% gray scale theory (I think proper name is Zone system if I am not mistaken) work for all metering mode? Say Matrix? I have a feeling it only works for spot metering.

The zone system is pretty much the same a matrix (less all the measuring and calculating). In zone you are measuring the tonal range differences in the images and are choosing a shutter/aperture combo to average out those extremes. This is essentially what matrix does. Zoning was/is common with old filmers when matrix metering wasn't available yet. It's a benefit to learn but not a necessary to use nowadays. Even Brian Peterson (author of Understanding Exposure) a very popular book, admits that matrix metering is superior than zoning for most applications.

Thanks a lotTravis. That is so much help. I will try to go out and experiment.

I am just tired of not getting what I expect and doing a lot of . I am trying to make my brain think for me not my camera as usually is the case. What I want should be what I get.
