[QUOTE="cwgrizz, post: 503262, member: 27017"] Just about the time I think I am getting a grasp on the EV +/- compensation concept, I seem to develop a fog in the brain. Ha! I have read and watched videos to explain how the camera works with the exposure and the gray/grey figure, etc. For me common sense seems that if I have a very bright scene ie washed out bright sky, I would want to shift the exposure to the negative, or if I have a dark forest scene that I would want to brighten it up with a plus compensation. I know that I read that the camera sees the bright scene a compensates by moving what it thinks the gray point would be up on the scale and thus underexposing the shot so the rule is to go plus with the EV. For me, I have not seen that work out. For the sake of illustration the bright sky scenario, when in Shutter Priority mode, 0 EV compensation the aperture is f9.0. Put in a +1 EV and the aperture opens (fstop decreases in number) which blows the sky scene out more. This is where I can't wrap my head around the written things I have read ie "Bright, go brighter" and "Dark go darker". Bright is the white sand or snow example I see most. Saying all of this, I do seem to have better results with BIF by setting the EV +0.7 or so. The sky ends up blown out, but the bird is not just a black bird shaped blot. I have been leaning toward the idea of ............... I don't know how I am leaning on this now. Ha! Please help me shape this in my mind with examples. Something that you may use for a rule on particular types of shots ie small dark bird in birght sky, light object in a dark woods, all dark, all bright... Thanks, I really think I just have a mental block (happens when you get old, no wait, it happened when I was young too.) :shame: [/QUOTE]
