  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Lytro adds perspective shift. Single camera 3d anyone

Holy christ... I think I need a second for the reality of this to sink in.
 
Yes single camera 3d for sure. Sooo, what else would this be good for?
 
You can only shift the perspective from one side of the sensor to the other. Technically it's useful for single lens 3D. But if you wanted single chip 3D you would need a sensor large enough to cover the inter-ocular distance. For larger inter ocular distances that means a very very large sensor and by extension lens.

I'm very curious, should it be like bigger than 70 mil frame?
 
It's a toy that takes ultra-low resolution images (lol) but some interesting tech behind it.
It has fantastic potential but there is still plenty of room to improve.
 
Canadian company, Isee3D already does this. They use an active polarizer in front of the front element
to generated 2 images. The IO is limited by the size of the front glass. It works though. I've seen it.

Or single chip, moving Iris (moves from side to side), sequential frames. Not great for fast motion but works. Maximum IA is approximately 50% of size of front element not accounting for any vignetting.
 
So what is the point as it stands now. Not much?

It's a toy with a certain degree of coolness. Nothing more, really. It's tech that can be adapted to more professional systems and larger sensors for specific-use applications at some point as sensor densities are greatly increased and sensor sizes continue to grow. Other tech is out there that accomplishes the same or similar objectives through other means, so this may not even be a glimpse of what will ultimately be. Just one of many possibilities employed into a consumer gizmo for now.
 
Some form of Lightfield capture is inevitable I think though. Choose your aperture creatively not purely based on sensitivity needs. Choose your focus in post. Choose your bokeh shape in post so that you can get anamorphic bokeh without shooting anamorphic lenses. Etc Etc.
