[QUOTE="WayneF, post: 364988, member: 12496"] Compensation is Not about f/2.8 or DOF - it is instead about obtaining desired exposure. It's what Eduard said, if you want the cameras metering result to be brighter, you add + EV compensation. If you want result to be darker, you add - EV compensation. Same deal with TTL flash and Flash Compensation. And yes, RAW images do allow substantial leeway for this adjustment in post postprocessing, but it is always good to get it near right in the camera (more important for JPG). Meaning good for the picture, and good for developing our own skill level. Reflective meters (camera meters) simply underexpose white or light colored subjects. And they will simply overexpose black or dark colored subjects. Just how life is. We can recognize this scene when we first walk up, and experience lets us often get the compensation about right before we take the first picture (this skill really helped with film). Or we can look at the digital result, and then compensate the second try. Digital skill seems often postponed until post processing. :) Recommended practice: Get a sheet of white paper and a sheet of black paper (craft store, maybe 18 inches large). Use it for the background of a picture of a black camera lens standing on black background, and a white coffee cup on white background. See? This is one of the first things we have to learn about camera meters. Here is WHY compensation is sometimes necessary: [URL="http://www.scantips.com/lights/metering.html"]How Camera Light Meters Work[/URL] [/QUOTE]
