Hi

I'm trying to create a shiny and smooth looking reflective amorphous surface.

Some of the DTE textures in the Bump channel look very soft, smooth and organic,

but when I try my own images (Photoshop based, Hi Res, 8-bit Grayscale or 24-bit RGB
 
Gaussian Blurred TIFFs)  in the Bump channel, I get PIXELIZATION and BANDING!

Pict Interpolation doesn't help.

I tried 16 and 32 bits per channel modes in Photoshop but couldn't make Bryce
 
"understand" these modes.

So how can I get SMOOTH image-based results in BRYCE? 

Thanks for your help!

pixelation suggests you might need a higher resolution rather then a higher bit-depth?
I dont know about the banding.. do u have a render and an example of the texture to illustrate what happens?
