Lunacore Photoshop Training - Photoshop Tutorials

I'm always bookmarking photoshop tutorials, but rarely do enough work with actual photographs to put them to good use. There is one trick I've yet to figure out, not sure if the Realistic Clouds tutorial here will help… I want to create a "difference clouds" type effect, but at print resolution, at least 300dpi. I did a small thumbnail sketch for a recent design, but it ended up having a lot more texture than the finished piece, because I had trouble getting the built in photoshop filters to create the same effects at high res as they do for screen/web work.
