1. Meter your gray card. 2. Meter the brightest area where you want detail. 3. Meter the darket area where you want detail.
========================================= D.....G.....B If the difference is the same on both sides expose per the gray card metering. ========================================= D...G.......B If the difference is less on the dark side (if it's a dim scene) close down 1/2 of the difference. This will let you get the highlight detail that would otherwise be lost because of the great exposure difference. ========================================= D.......G...B If the difference is less on the bright side (if it's a bright scene) open up 1/2 of the difference. This will let you get the shadow detail that would otherwise be lost because of the great exposure difference. ========================================= "Difference" is how far off-center the gray meter measurement is. You'll want to effective move it toward center without disturbing the overall exposure too much. ========================================= Feel free to bracket just to prove it to yourself. This is how all the fuss about the Zone system boils down.
