I find it doubtful that any b&w emulsion would be less "grainy" than color, primarily because in B&W, the silver halide crystals remain in the emulsion, whereas in color the crystals are used to activate a dye (which makes up the image) and the actual silver halide is then washed away in the bleach stage of color processing -- thus, there are no actual "grains" but the remnantsof them left in color emulsions.
---Yes, but that's being overly pedantic. When those silver grains are bleached out of the emulsion, the blobs of dye left behind take the form of the silver grain that vanished. Maybe the dye will bleed a little, but that dye blob will look like grain. In a print what we perceive as grain is actually the space between the grains. At that point, there's no practical difference real grain and color ghost grain. --- LV __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier.
