Faded Colors in Photoshop CS6
What profile do you use in your DSLR ? Do you photograph in JPG or RAW file ?
You have activated the color management in PS BUT you don't have ticked " Profiles mismatches", "Ask when pasting" and "Missing profile". So, when your photo came to Photomatix, you don't know if Photomatix assign a profile in your photo and mainly witch ?
I am a french photographer so I am sorry for my english but i have translated my Smart Guide to Color Management in English with a friend :
It's free ! I think you'll find the answers to your questions with it !
