Title: New camera (change the focus of a picture after the shutter clicks)
Post by: Teen Wolf Blitzer on June 23, 2011, 12:46:27 PM
Sick!  Take a look at their website.  Seems to be a P&S.  Seems it would be great to implement this into an SLR.  Wow.  That is cool.

Interesting.  Will have to look past the 'it's magic' marketing-speak to find out how this really works.

First thought is simply an automated composite of multiple exposures with varrying focus.  Pretty cool 'select the focus target' demo on the Lytro site: http://www.lytro.com/picture_gallery (http://www.lytro.com/picture_gallery). Playing with those, there seems to be about 3 or 4 distinct focus depths, not infinite.  Noticed that distant objects in a few of the photos cannot be brought into focus.

You cannot make a single lens reflex sensor and the sensor in the lytro work together.  You could, however, put better glass on a lytro-like camera.

The original technology of the light-field sensor was developed for microscopy - it gives a distinctly better alternative for 3 dimensional imaging than traditional ccd sensors that are commonly used in confocal laser scanning scopes and 2-photon scopes.  those microscope objective lenses ofter cost 10s of thousands of dollars, so there is room there for better cameras than what they released now...

i think i am going to get one eventually, though i don't imagine it will be that good for low-light.

quite expensive!

maybe rangefinder-like?
