Great... once you get to know it. – Glass Tilt Shift Review

The good: Really quite excellent photographic tilt shift or blur vignette effects. Pops highlights well, and the bokeh are very nicely detailed. Chromatic abberation, option to add grain. Really good stuff. Quite often even desktop applications don't all of this well. The bad: The controls/UI are not terribly intuitive. You won't really know you can move the focal point until you try it. The glow (really should be a secondary effect) is controlled by the slider, which is all you try initially. The different modes along the bottom are not indicated in any helpful way. You really have to play around with this for a bit to get a handle on what it can do. But if you put in a little time, it really is powerful, offering quite good quality. Very organic looking.
