But even if you have true vector output devices (like a Montage FR1 slide writer) you are still limited - the best film resolution is about 3000x3000 points (Kodak Ektachrome). But who cares if you're limited to THAT resolution? :-) >Trouble comes when you try to set the lower bound of acceptability. (The >Amiga's best graphics modes haven't reached that lower limit yet, imo. >But the cost of devices that currently do...) Sure, not everybody can buy a Montage. But in the ms-dos world it's the same, and yet there are lots of programs who can export vector graphics. I hope ProDraw 2.0 will be usable....unlike v1.0. What I'll try is to export a good business chart in The Advantage (as soon as I get it) in Aegis Draw Plus format, convert it there into HPGL and either take that into Harvard Graphics as a Lotus 123 graphics import or send it directly to the slidewriter, who does HPGL files. We'll see if it works. >------------ >"...Then anyone who leaves behind him a written manual, and likewise >anyone who receives it, in the belief that such writing will be clear >and certain, must be exceedingly simple-minded..."

Get a bigger negative, and you need more points. (Which is why I'm looking for a view camera again. 35mm *used* to be good enough.) There are several films that can beat the daylights out of Ektachrome (not to mention having better color characteristics. Most of them being non-Kodak products. Ahem. ), such as Kodachrome 25, or any number of astrophotographic or microfilm emulsions. Two or three or more times the resolution. On the other hand, Ektachrome does the job just fine for a lot of people. Just how low an image resolution is effectively indistinguishable from "perfect". (Sit back and watch the flames burn brightly. :} ) And remember that what *used* to be better than adequate will become unacceptable as people's expectations increase. ------------ "...Then anyone who leaves behind him a written manual, and likewise anyone who receives it, in the belief that such writing will be clear and certain, must be exceedingly simple-minded..."
