CORRECTION - Making 2 separate scans to preserve details in shadow and highlight - Photography

    Sorry for the mistake, but the tecnique remains the same for layer
    composite and erasing to bottom layer.

    Actually, what I think would be nice would be a variation of a feature
    my old Canon T-90 had, a multi-spot mode where you point the 5% circle
    in the middle on your highlight, press multi-spot metering button,
    then point the spot to the shadow, and the meter averages the exposure
    (imagine a subject on stage with a white t-shirt, then point spot to
    black of background and camera calculates average exposure), the same
    could be done digitally (theoretically).

    Take a spot meter reading of darkest tone and then designate hrightest
    highlight - and camera calculates and compresses range to hold detail
    shadow in foreground of darkened room AND highlight in scene outside
    window. A challenge for camera chip engineers...

    Just my UNscientific opinion.

    There seems to be a fairly heavy grid/noise pattern on some of your
    photos taken in bright sunlight. For example,

    equipment are you using?
