I've found that a better simulation is to switch from RGB to HLS mode, then save the L (Lightness) layer as the BW image. It seems better to me in the sense of more closely matching what I typically see in a BW print w.r.t. the grays that colors get "mapped" to. > monochrome print but usually with a blue or green tint.

Every try doing it on a 600+ dpi laser printer? Probably couldn't do much better than a 150-line screen, that way, though. But there won't be a color cast! :-) TTYL, DougF KG4LMZ - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
