Holy crap.
Although I can hear the "purists" lining up outside as we speak to give everyone a lesson in "Photography 101" that will start with FILM and end with FILM since "playing with paper and caustic chemicals in the dark" and "being able to foresee every possible thing that can go wrong in selecting the proper aperture, shutter speed, ISO and lens choice" are the only true attributes of a REAL photographer.

Looks very interesting. Algorithms for un-blurring images aren't anything new, but the clever part of this plugin seems to be it can work out the movement of the camera - which defines the point spread function (maybe?).

As fascinating as this topic is, and as much as I want to understand the details, my brain can't comprehend pages like this.

So instead, here's some photos:

Interesting.

However, to be a buzz-kill....

It's only de-blurring a certain kind of blur. From what I can see in that video, it's not focal, but slight motion aberration. Honestly, that's the easiest one to fix, as you can realign and undo some of the motion. Still impressive, but not blow-your-mind impressive. I would imagine it has limited usage, too, such as slight shutter slowness compensation. I would imagine it could fix an image within 1-2 shutter range, similar to the range boosted by VR/IS focal systems.

Beyond that, I would suggest it will mostly help in forensic recovery (pro or amateur), and not as a way to "fix" bad images. A bad image will always be a bad image, although you can make it less crummy with good filtering.

NO: "Wow, what a great image of grandma!"
