Well, not too familiar with your particular situation although I do own DAZ and P.S. 7. But your images must be saved to a format that P.S. can handle as Boofy suggests. As a reminder, you can set certain parts of your DAZ composition as “invisible” and since you can render certain scenes with objects as invisible, you can render scenes with all sorts of invisibility and render them as separate files only to compile them all under one file in P.S. to handle as you see fit as layers and giving you more versatility in the ultimate composition.
