[I can see for miles and miles and ....] In response to the HippoVision query -- You can easily get 8 grey levels with a color monitor. I could never figure out how to get 16. I tried the HippoVision on a monochrome monitor initially, too. I also got the same results which were described, namily, vertical bars of what looked like hash. I spent about one hour fiddling with all the controls (thresholds and such) with no useful effect. Turns out that only two grey levels (on and off) are available when using a monochrome monitor. Bottom line -- use two levels in black and white. The auto set-up stuff really did seem to work. I'm a tweaker at heart and could get a limited (subjective) improvement in image quality by playing with the software controls. BTW -- We ran some of my images through Tom Hudson's ray tracing program (STart Spring 1987 issue) last night. Lot's of fun! It also makes you appreciate Crays! -- paul drongowski decvax!cwruecmp!pjd case western reserve university pjd%Case@CSNet-relay
