Worry not, Shiva, the intent of the tutorial has always been for everyone here... I'm just speeding it up a little now that HT has shown interest. It will be available to all when it's done.
As for PSP... Like I've said, nothing in this technique is terribly fancy or high-end, and I would be very surprised if most midrange pixel-based graphics programs can not do any of the steps. As for specifics... I have never used PSP, so I cannot comment on its abilities. I guess you guys here will be Beta testers.
I can tell you upfront about some requirements, though.
A. You must be able to have multiple different layers in a single file. (about 10-15 typically)
B. Each layer must be capable of its own transparency setting (i.e., multiply, screen, overlay).
C. You must be able to colorize a greyscale image (the elevation map) in different ways.
Everything pretty much centers around these three things. Anything else is just a matter of doing something the easy way or the hard way.
Tutorial should be ready in about... 2 weeks
