Dark mist, let met put it in a nut shell:
Make a image in bryce (on wincustomize they LOVE dolphins

)
when you think the image is ready, push the big round renderbutton.
The image will render, and when its done, you have a nice, clear, collor full image, with a lot of dolphins

),
Then go to: file>export, and export the image as a .bmp file.
You can vieuw the image already yourself.
Now open photoshop, and open the file you have made, the bmp file.
Addapt it with one of your 1337 skillz, and then go to: file>save as, and then select .BMP, or .JPG. (when you want to save it normal in photoshop, you get a .psd file.)
hope this cleared things up for you.
