PMJI Edward, << Im working with the Penello demo, trying to decide if I want it. Ive pretty much answered the questions I had by observing the previews, except for how alpha works, which I assume can only be observed with the fully operational software. >> Alpha channel manipulations are not *fully* supported as you might think. You are allowed to choose the source of the alpha channel to be used in the output. There are 3 choices: NONE (black), SOURCE (existing, from the Source image), & BRUSHING. The latter uses the alpha from the brushstrokes (placed in the output alpha channel), as specified from the OPACITY dialog panel. From there, you can invert the alpha channel if desired. That's about it, I believe. BILL
