Attached Link: Stair Interpolation Pro 2

Fred Miranda's Stair Interpolation Pro 2 works better than Genuine Fractals and costs only $ 24.90 Anyway beware, if quality is #1 concern, interpolated images will never look as good as non-interpolated images in top quality prints (such as quality coated photo book pages). For low quality prints (such as home inkjet printers), the trick may actually be useful.
