Pretty Good

Its great and It does exactly what it says!! you should also check out Blurred Photo. It has much better controls and more features and its only .99cents!! Its similar to Colorsplash where everything in the photo is blurred then you touch the areas you want to be clear. It has an undo icon and an eraser icon in case u make a mistake, it also has an eraser icon. you can pan and zoom to work on greater details just like in Coloraplash, and those are just a few fetures just to mention. I have both Tiltshift and Blurred Photo but I use Blurred Photo more. Hope this helps it decision in which app to purchase.
