This is probably the best way to create porn pictures, as stealing them will be pointless if you don't have the right viewer for it.
As you remember, Apple got out of the digital camera business in the 80s. The product was generally acceptable but prove to be too premium for consumers. People bought into the Kodak digital cameras and I remember wanting to have one of those.
Lytro imaging doesn't quite cut it for me unless I am shooting porn. I mean, what better way to entice people to drop by your site? It would be a killer of a success for pornoghraphers.
If you look into the business model for porn sites, they all require you to sign up and be a member before letting you have access to it. Once you are in, you leach all the content from them, set up your own porn site and you're charging half as much as the original producers.
With the Lytro image, you can't misappropriate content as images can only be appreciated through a dedicated webviewer or app. Not a bad idea really. So is Apple going into the porn business? I hope so. If his is ever a reality, that's where 3D porn is going to explode.
