I've installed ACR 4.5 and have downloaded the profiles. When I open up a Canon 40D image in ACR, all I see under the "camera profile" tab are the "camera" (faithful, portrait, etc), the "Adobe Standard Beta 1", ACR 4.4 and ACR 4.2. I'm trying to load a Pentax k10d profile but don't know how to do so.
I tried pulling it up in the DNG editor and exporting an unmodified k10d profile after choosing "choose external profile", along with a few others, and that gets them to appear in ACR. However, those exported profiles all look identical to one another. How can I load the profiles that I downloaded from Adobe, the ones from that huge list in the "Adobe Standard Beta 1" folder, into ACR? I'm trying to get my 40D to look like a Pentax k10d. It's late, I'm tired, so I apologize if I'm missing something obvious.
