Still playing with faking lensbaby blur in Photoshop. I like my previous attempt; this isn't quite as dramatic.
So far, it takes quite a few steps to get something like this. Warping, pinching, spherizing, duplicating, bluring, polar coordinatess, more bluring, un-polar coordinating, blending.
The blending is the hard part, trying to apply masking layers in a way that realistically reflects the proper Lensbaby blur + distortion without causing sharp focal differences between the focal point and the distorted remainder. It may require more intermediate layers between each filter, say an extra layer between each blur filter at least, to allow an even transition between in-focus and delightfully not in-focus.
Hmmm.... I ponder further.
