Newbie question - 16 bit per channel capabilities?

I am completely new to Ultra Fractal and would like to create images that can be saved in 16 bit RAW file format. While Ultra Fractal does not do this natively, it appears Ultra Fractal is only using 8 bits per color channel.

Is this correct? Is there a way to use 16 bit color channels? I am actually looking to use the images for heightmaps, but would like 16 bits in a single color channel.

Unfortunately Ultra Fractal does not currently support image formats with 16 bits per channel when exporting or rendering. It's on my wish list for future updates, but I haven't received many requests regarding this feature yet.

I really like UF to add this feature...while fractal artists trying to have best prints, it can't stay with lack of quality color space.

RAW would enhance Photoshop post editing as well. I'd love to see it added.
