[QUOTE="voxmagna, post: 496068, member: 38477"] That is useful background history - Thanks. I'm not putting the exposure metering in the equation because I know the camera only meters selected points and the overall results (for highlights) can be a lot different. I'm bracketing several shots 1/3 stop, checking afterwards on preview what highlights are clipped. Then import the file into PC and seeing the foreground under exposed as on the lcd preview. If I put the same image on a plasma TV I get the same thing. Only after modifying the gamma curve can I lighten foreground lowlights without clipping highlights. Do you know if the Nikon 'scene' modes do any curve bending? I don't have a grayscale test chart to try mine out. On the D750 I've dialed in -1/3 stop EV correction which helps, but that is just compensating for its metering decision and not changing the fundamental dynamic range. I agree with what you say about under exposed results because when I look at pictures taken by other cameras, I can spot the clipped sky straight away. It is almost as if this is becoming the accepted norm. even on TV. I have looked at some shots where the lowlights appeared to have very little detail, but when lifted in post detail is there. That is re-assuring when you get back a shot that appears badly underexposed. [/QUOTE]
