Shoot now, focus later: Change the focus after you take a photo

Dave Johnson | April 22, 2013
The line separating reality and science fiction continues to blur. Whereas 40 years ago, cameras that focused themselves were unfathomable, auto-focus lenses have been a routine part of photography since the 1980s. Fast forward to today, and you can purchase the Lytro camera, which does away with the idea of focusing entirely: You can change the focus of Lytro photos after they're taken. The coolest part? I'm going to tell you how to simulate Lytro photos with the camera you already own.

When you're done, go to the Chaos Collective's Make Your Own DOF-Changeable Image page and choose the file you just created. After a few moments, you'll see your video transformed into a still image that you can click to change the focus. It seems magical.

Afterwards, you can click the upload and share link to post your creation to Twitter, Facebook, and elsewhere so other people can click around in your photo as well.

This should work in any browser, but I have had the most success viewing these images in Chrome. Here is the variable-focus version of a photo I shot on the Santa Monica Promenade.
