This is a really bad app, the buttons do the opposite of what you would expect them to do, the blur effect is pixelated, and the darn thing crashes with simple use of the undo command.
If all you want to do is make a city shot look like a model town, then it would do the trick.
The one redeeming feature of this piece of garbage is that I was in fact able to drag and drop a photo from the iPhoto app! However, there is no progress save, so expect all your work to go bye-bye not if, but when it crashes.
Lastly, if you download this app after MY warning then the stick has been passed, and you must write a warning twice the length of mine. Bwahahaha!
