Unfortunately, I continue to take blurry photos. The problem is that I can’t always see that the photos are blurry on the small screen on the back of my camera (even after zooming in). However, thanks to Unshake software from M.D. Cahill (via Lifehacker), I am able to make my blurry photos less blurry.
I’m sure you could improve blurry pictures with Photoshop or some other commercial software package, but Unshake is free and available for all platforms.
