What is Light Field Camera ?

From what I could understand. It uses microlenses(just before where sensor is placed )
Each lens focuses ,and capture light in its path . Later all the images are stacked together.Similar to Compund eye of a Housefly or any other insect .

compound eye .

just think about this in miniature form

Its nice to see various type of new innovation in the field of photographic instruments. This looks good, but practically, specially for enthusiastic photographers, it is of no use.

Actually for photography it may not be very useful since photographers like to focus on the subject and eliminate other things with great bokeh

but for normal P&S users its very useful and also for macro photographers :D

Click to expand...

Basically ,Its not meant for that .It meant for the user to fiddle around with the picture while looking at it .Giving a whole new dimension /Perspective .

Secondly ,It will mostly find space in Digital Photo Frames(I'm sure they will support this format in future].

Infact ,you may see this Technology in DSLRs in next 5-6 years from now on .

Soo basically like in RAW format we can have exposure and sharpness corrected afterwards similarly in this thing we can even select the focus afterwards :D

Soo whats left for us then :)?
