    Curves! not exposure, if you can.... why?

    you may already know this.... why? 1-2-4-8-16-32-64-128-256-512-102... you get the idea, at the TOP of the numbers, the brights have alot more gradation, whereas at the bottom, in the shadows, there's not much gradation there, so you get these banded-out shadows too easily...

    Due to the way digital images are stored, ideally it's better to slightly over-expose rather than under-expose, as long as you don't blitz the highlights....

    If you're doing much exposure adjustment, try to make sure you're NOT in an 8 bit per color mode, try to have your file in a 16 bit per color mode, (depends on app, but NOT automatic)

    • I always understood it as the other way around, with shadows hold more info than highlights.sequoia
    • Plus it's significantly easier to correct for underexposure. Blowing your highlights out, even just a bit can ruin a good photo.sequoia
