Sneak preview of the new photoshops unblur function. :o

I thought it was a fake but im not so sure now,

Iris can do stuff with PSF point spread function of images to correct blurry stars. Trouble with Iris is it's too darn clever hard to use for it's own good - if it was just point and click like PS...

Very interesting.  It's not fake - it's performing blind deconvolution which is, in general, a very difficult problem.

The examples in that video have pretty much homogenous point spread functions.  This makes things a bit easier but it's still very complicated.
