I came across this while looking for ways to enhance my prints. OnOne Software. They provide plugins for Photoshop to do various tasks with your photos. The plugin I was interested in was Genuine Fractals 5. It was a way of letting you get large prints from small images. For example, if you had a 6×4 image and wanted to get it blown up to 18×12, normally you would get pixelation, frayed edges and all sorts of others issues. Basically the print would look crap. With this application though, you can enlarge Images up to 1,000% or more. Sounds to good to be true. Well, I am about to download a trial version and put it to the test. Have a look at the website OnOne Software. They have a ton of different plugins.
