If anyone is interested in helping me check my white balance conversion
parameters, I've put a little Windows shell executable (and source) up at

    <http://www.panix.com/~johnf/pefconvert.zip>

It should be used as follows:

    pefconvert inputfile.pef outputfile.jpg n
or
    pefconvert inputfile.pef outputfile.png n

where n is a single digit in the range 1-8, specifying the white
balance setting to be used, as follows:

    1: Daylight
    2: Cloudy
    3: Shade
    4: Daylight Fluorescent Light
    5: Neutral White Fluorescent Light
    6: White Fluorescent Light
    7: Tungsten Light
    8: Flash

The output file is a half-resolution (1520 x 1012) JPEG or PNG
(for easy quick-and-dirty conversion from raw sensor values).

It should, assuming I've got everything right, produce images
that have the right overall brightness and colour balance - please
let me know if you try it out and get gross errors.  It does *not*
produce images that are directly comparable to the output from Photo
Laboratory; I have not yet applied any sharpening, and it also looks
as though I may need to apply a little additional saturation.

Note, too, that this is test software, not industrial-strength: it
doesn't check for error conditions.

Please send any comments to me, off-list, at [EMAIL PROTECTED]
