Hi,
This is my first post here and I'm a newbie with Argyll & profile
generation. That said, my background is engineering/computing/maths/physics
and I'm familiar with the application of icc profiles.
I'm looking for some advice/tips on using argyll for a slightly "off the
beaten path" application.
I'm copying 35mm transparencies using a halogen illuminant and a good
quality camera. I take a number of raw exposures to maximise the dynamic
range and combine these (using my own software) to generate a HDR image (in
.exr format). Raw processing is done using dcraw.
I would like to generate an appropriate camera profile to allow me to
maximise the colour gamut of the resulting HDR image.
Using ImageMagick (Perl API) for image processing and application of icc
profiles and have a collection of Wolf Faust transparency targets.
Looking to color match the information on the slide as opposed to the
original scene.
I guess my main questions are:
1. Is it better to profile the low DR raw images prior to generating the
HDR image or is it possible (using argyll) to simply profile the resulting
HDR image.
2. I understand that argyll crunches the data to generate an icc profile
in floating point, but can it read in image data in floating point? (eg
.exr format)
3. Are argyll's icc profiles suitable for applying to HDR images? (using
lcm's as implemented in Image Magick)?
4. Any other questions I SHOULD be asking? ;)
Best Regards
Mike
