Some packages allow you to pick a preferred intent that will be used in
certain cases but you can use any intent you wish and can over-ride the
intent so to speak in an application like Photoshop. Photoshop 6 makes the
choice of intent so nice and easy as it provides a "soft proof" in the
Convert to Profile dialog in real time as you try different intents.

Hence if your goal is to get the best possible conversion with the profile,
picked one on an image by image basis using the Convert to Profile command
in Photoshop 6. Some images will produce better results with a Relative
Colorimetric intent where others will shine with Perceptual. Now if only
there was a way to do this automatically. There soon will be! Stay tuned for
a Photoshop "add on" that will be able to analyze each image and apply the
profiles and intents that would produce the best conversions. It will do
this in a batch processing routine of course!

ProfileMaker Pro is a pretty amazing product. I've yet to find a package
that can beat it in terms of profile quality, ease of use and elegant
interface. I can tell you that ColorFlow produces very good RGB output
profiles but isn't so hot with CMYK, at least in my experience. If you have
any desire to produce CMYK output profiles, ProfileMaker Pro is a much
better (but more expensive) choice IMHO. ProfileMaker Pro also makes
stunning RGB output profiles.
