[Bf-committers] A new photo format

[Aurel W.]

Hi,

maybe noticed this thread a little bit too late. But there is an addon
in trunk, called 'light field tools', which I created to setup light
field rendering in blender (a camera grid). This can then be used by a
light field rendered to adjust focus and a virtual aperture.

I used this to render some light fields with extremely high angular
and spacial resolution, way higher than what current light field
camera could capture in one shot.
