Oliver Loch: Here're some simple ideas how this technology could be used (software permitting):
Adjust focus: Useful if accurate focus is difficult to achieve, for example with moving objects.
Refocus: Useful if you change your mind about what should be in focus.
Selective focus: Like painting with light (aka dodge and burn) you could paint with sharpness and blur.
All in focus: Like focus stacking, great for macro
Non-parallel focus plane: Similar to tilting the lens you could tilt the focus plane. Useful for architecture, portraiture, product shots etc.
Non-planar focus area: Have the surface of a curved or oddly shaped object in focus
Focus masks: Use the depth information to create masks in photoshop, for example to desaturate elements that are further away or to easily select and replace a background.
Displacement maps: Use depth information with photoshop's displacement filter to wrap another picture around the image
Relight: Use the raw light field that has the directional information of the light to change the brightness of the light sources or adjust their colors in mixed light situations.
Compress: Use the depth information to compress the perspective as if the picture was taken with a longer lens.
There're probably thousands of other ideas just waiting to be thought of. So I'm much more excited about what could be done with this technology than I'm concerned about what the initial technical shortcomings might be.
Follow focus: killer app if the camera could shoot light field videos
3D from one picture: Use depth information to create (limited) 3d objects similar to what helicon focus can do as a side product of focus stacking.
Stereoscopic light fields: Use two light field cameras for 3D movies with additional depth information (which would allow you to move the head a bit a see a slightly different image) or to render an area sharp depending on what the viewer is looking at.
Lenticulars: Use depth information with lenticular prints
Embosser: Combine the light field camera with a device that creates a relief of the scene. Useful if you want to share pictures with blind people. Or take a portrait, inverse the depth information, use with a 3d printer and put it on the wall to have the person watch you.
