I think it's easy and fun. Take some time to look at some of the top dreamers on the site. Figure out what image treatments you like best and then try out similar images of your own to see what results you get. I delete about 2/3 of the images I create. I usually cue up 3 or 4 images at once (its super quick to do) and then work on something else. When I remember to check back on them, they are usually done processing. I delete the bad ones, and cue up 3-4 more to process.

Thank you very much for the advices! I will definitely try it! :)
