Refocus Imaging is working on technology that would truly be of value to me, and a lot of other occasional photographers.
Via a combination of new optical hardware and software, they allow you to change the focus of an image after it has been taken.
This Crave article includes an interview with the company's CEO, but doesn't explain the technology in any real detail.
Click on the image to see some examples of the technology in action.
I'm not sure whether this is a Flash based version of their software, or just a mock-up of how it works.
In any case, you can check out more images in their gallery.
I just hope they can fit this into a nice compact camera ... and for a reasonable price!
