When you select an intent, Photoshop and other apps use rel col for
the device->PCS transform and then your chosen intent for the
PCS->device transform.
Actually, if the source profile is two-way and supports multiple
rendering intents, Photoshop uses the chosen rendering intent for
both sides of the conversion -- it started doing that in Photoshop 6.
If the source profile is one-way and supports multiple rendering
intents, Photoshop 7 uses the chosen rendering intent for both sides
of the conversion, where Photoshop 6 always used relcol.

The ICC changed the spec to allow multiple intents for scanner (i.e.
one-way) profiles after Photoshop 6 shipped and before Photoshop 7
shipped. We support this new feature in Photoshop 7.
If the source profile is two-way, multiple intents where always
supported. The change is only for one-way input profiles.
So there you have it from the horse's mouth, so to speak.
