I don't know how many of you have heard of Lytro. The camera came out with the concept of Live Image. I haven't played with one, but it seem like an image that refocuses/changes the depth of field. I would love to get my hands on one of them, until then I am playing with my Lumia 1520 and the Nokia Refocus app.
The images below were taken with the Nokia Refocus app and you can refocus by clicking on the part of the image that you would like to refocus. I have not figured out how to do post processing on them, so this is the raw image as taken by the app. Pretty cool, but I would like to do some edits.
I am also looking to find some sort of medium that will allow images that refocus, such as the Lytro Living Image and this Nokia Refocus image, in order to be a product for consumers.
NOTE: Sorry the page display is not iPhone friendly. Trying to figure out why. Larger screens work fine.
