When you get ready to give it a try, Gene has a "how to" book and video that are well worth having. I believe I got mine at Bostick & Sullivan.
Congratulations, Gene and a tip of the hat to Jason.
I have to admit that I'm interested in the process as well. The range of expression possible as I have seen between for example Gene and Emil (Gandolfi) shows what a powerful, flexible, and expressive medium this can be. I consider it to be "the next level". Now to find the time to try to take it there. How wonderful to have these guys in our community. Thanks Gene, for existing in the first place. It's truly an honor, privilege, and an inspiration to be curating the APUG featured portfolios.
