    Default Image processing software



    Is there some kind of software which would enable me to load a high
    resolution b/w image and colorize it using a much smaller color image of
    the same object?
    Basically, I'm looking for something that would extract chrominance data
    from the small image, resample it and apply to the large b/w image, a sort
    of thing JPEG uses all the time.

    Adobe Photoshop or any comparable general-purpose image-editing
    application can do this kind of thing, but would require you to scale
    and align the images yourself. Photoshop has a batch mode (some
    others may as well), so to whatever extent the source files are
    consistent some of the processing could be automated.

    I've heard astrophotographers mention a program called Registax,
    which may be able to do the registration steps for you, or at least
    make them easier (and might have channel-mixing capabilities as
    well). You might want to ask this question on
    alt.binaries.pictures.astro; many of the participants who do colour
    work with digital cameras "bin" their RGB exposures, i.e. use 2x2 or
    3x3 blocks of pixels for smoother, lower-noise colour channels, to be
    combined with their full-resolution luminance exposures. Here I think
    the alignment issue must be fairly trivial, but the general principle
    is the same. When posting to ABPA be sure to include "Astro" in your
    subject line, as many readers there filter out messages that don't.

    Ok, thanks a lot for the help. I already found the thing I'm looking for in
    Photoshop - turns out the color mode is called "Lab color". This gives you
    a luminance and 2 chrominance channels, just what I needed. It's still a
    bit of a drag to manually align the images, but what the heck!
