Alien Skin's Exposure 2 is one of my favorites because it lets you replicate a long list of great-looking film stocks, as well as easily make your own b&w and split-toned versions. (For the truly nostalgic, the program also comes with a module that will let you replicate old-school color film, too.) Exposure 2 works with Photoshop, Photoshop Elements, and Corel's Paint Shop Pro Photo XI. Here are four great ways to make better-than-average monochromes, and for the heck of it, one fun re-colorization. To do it yourself, download a 30-day trial at www.alienskin.com.
