Topaz Labs is a filter series developed for Photoshop and they do various things to your images. The most popular would have to be Topaz Clean. It has the ability to do many things but my favorite would be to "clean" up the image by removing sharp edges and everything while keeping the colors and such in order. Feel free to search up Topaz Labs on Google and you'll find out all the features and whatnot. I'm not an Encyclopedia y'know:rolleyes:
