I was about to download a trial version of Silverfast and discovered that I don't know which to DL. One version sets up a Photoshop plug-in, the other is for "Twain." So, what's Twain? Why would I want a plug-in as opposed to Twain, or vice-versa? I couldn't find an explanation on the site that defined the differences or why one option should be chosen over another. Is anyone using SF with PS CS on Win XP? How's it working out for you?
