Can you describe this process? It sounds interesting.

I haven't compared a 32-bit render to a 8/16-bit file size, but I'm guessing it's 2 or 4 times the size (that extra info has to go somewhere).

HD storage is cheap - just curious why the filesize is an issue.

I'm very comfortable with photoshop and am always on the lookout to learn something new (especially from someone experienced), thus my questions.

After I was exposed (forgive the pun.. hehe) to 32-bit frame buffer and Image -> Adjust -> Exposure in Photoshop, I'm a huge fan of it. While maybe not perfect, it's certainly acceptable (to me, anyway). The ability to take a completely overexposed and blown out render, move a slider, and it looks pretty darn good... is remarkable.
