Thanks Lynda.
I don't know of very many sources, although I know a lot of people do like to do this. There is a group of folks over at a Commuity Zero site that are dabbling in things like this. Their address is:

As for myself....I'm sort of self taught. I got some tips from Adobe's website, and then played around modifying the techniques. My goal is to replicate natural mediums, rather than create digital art work. For me, the trick is to use the filters in Photoshop as part of the process, rather than a one step measure. Mix em up, fade them, and blend them. That's how I do it.
I have yet to make a tutorial for one of these, maybe that's next. It's just that it's very involved and I'm not sure people are up to going through a long tutorial.
I think a grouping of photos done in a Sepia style would look wonderful. I'm thinking of doing it myself.
Thanks for the use of your photo.
