This sounds very exciting. To play the devil's advocate however, on most of the example photos on Lytro's site, you really only need two points of focus - roughly near and far. Clicking on those two shows you everything there is to see in a picture.
If someone comes up with software to allow refocusing on two distance points with existing photos, they could eat Lytro's lunch. Can Picasa do something like this?
- rythie 15y agoIf you have a photo that's all in focus (i.e. f15 aperture or something) you can throw parts out later with using masks in a photo editing tool, though it's time consuming. I'd suggest you could get a similar effect with a camera that had two or three lenses using different focal lengths. Fujifilm already released a camera with two lenses: http://www.dpreview.com/news/0809/08092209fujifilm3D.asp http://www.dpreview.com/news/0809/08092209fujifilm3D.asp so it's just a software modification for that.
- tintin 15y agoUsing a photo where all is in focus you only need a depth-map to process the blur. I think something like the Kinect is making this possible already.
- dj_axl 15y agoAccording to Wikipedia this is called "focus stacking", combining depths of field to create a larger depth of field. The page lists a number of apps/plugins that blend photos to create this effect: http://en.wikipedia.org/wiki/Focus_stacking http://en.wikipedia.org/wiki/Focus_stacking
