The tutorial I link to is so good, I wish I had produced it! Several people have tried to explain ACDSee's Pixel Targeting tool, and have not done so well. I did one early on when PT first was released, but It wasn't very good and I removed it from this blog because I was ashamed of it!
I won't call this the best Pixel Targeting tutorial ever, because who knows, a better one might come out tomorrow! But it is the best so far!
The Best Pixel Targeting Tutorial so far!
