[comp.graphics] 24- to 8-bit conversion

How do you all convert a 24-bit image to an 8-bit image?  Mine always
end up slotchy and kinda scruffy.  My software (Photoshop, Mac II) provides
pattern and diffusion dither, but one looks, well patterned, and the other
looks splotchy.  I've experimented with merging neighboring, similar colors
into one, but that ends up looking like an oil painting.

How does one create a stunning 8-bit image from a stunning 24-bit scan?

Any replys via e-mail welcome;  I'll summarize to the net.

Thanks much,

Nate.
