I'm self-taught on Painter and I was wondering if anybody out there could share some ideas about how they are using painter in the realworld. I'd like to work on some larger files but on my Celeron machine the brushes just slow to a crawl on any thing other than postage-stamp size. I've looked at books like Painter 6 Wow and they seem to have examples of some good size prints, but when they mention file sizes in any examples they seem pretty dinky. Is anybody out there using Painter to produce anything in the 10 to 20 MB range? Any suggestions for how to work in larger sizes?
