Overexposing Sunsets and Retaining Saturation

    OK so I tested JPS's claim that overexposing a sunset won't lose
    saturation if you darken in post-processing. It worked. In daylight
    conditions there is a risk of irretrievably losing blue in the sky
    before the blown highlight warning flashes but in a low contrast sunset
    it does work and gives a less noisy image. I just tested this with
    jpegs, it's not even necessary to use RAW for this trick. I did also
    shoot RAW but it was simpler to do the comparison with jpeg.

    Here's the two imortant images in the comparison:
    originals:
    <http://www.edgehill.net/1/?SC=go.ph...o/view/2005-11-18-sunrise/compare&PG=1&PIC=2>
    With levels applied to equalize:
    <http://www.edgehill.net/1/?SC=go.ph...o/view/2005-11-18-sunrise/compare&PG=1&PIC=1>

    And the final raw conversion is up one folder from there, although
    that's not really part of the test:

    In message <>,
    It's all just numbers. Gotta use as many of them as you can.

    Of course, some individual cameras may have issues (especially with
    JPEG).
