ive heard on a few websites to overexpose or expose to the right is a good technique. here is a sample excerpt:
Within the second F/Stop, which contains Bright Tones 1024 levels available
Within the third F/Stop, which contains the Mid-Tones 512 levels available
Within the fourth F/Stop, which contains Dark Tones 256 levels available
Within the fifth F/Stop, which contains the Darkest Tones 128 levels available
If you don't use the right-hand fifth of the histogram for recording some of your image you are wasting fully half of the available encoding levels of your camera, and it would give you a major advantage to bias your exposures so that the histogram is snugged up to the right, but not to the point that the highlights are blown.
My problem is, all my images are exposed in the center or to the left. Anything else always blows out highlights. I find this technique impossible. Any advice?
