Photiosity is an application to sharpen blurred and shaky photos. The program tries to estimate the type and size of the blur in order to determine the original sharp image. For Macintosh (Mountain Lion, 10.7, 10.8 or 10.9, 64 bit), you can download here a demo version of Photiosity.
We will not continue to develop Photiosity. A new written (Cocoa) and much improved application is Photiosity2.
