It's true that 3D has come a long way but never assume that just because a production has money that means they know what they are doing . 3D movies being made now still "break the frame" with total disregard. They disregard scale and they continue to edit for a 2D presentation even though doing so does nothing to enhance the 3Dness of the movie. In fact, it hurts it...... I could write about this all night but I'd rather let it unfold naturally if anyone wants to talk in detail about stereoscopy. But I will say this; there is no difference between making a single 3D image and shooting 3D video. I've done both and they both use the same 3D window.

What is a 3D window?
What is parallax?
What is divergence?
What is Inter-occular distance?
What is Point of Convergence?
What is inside the frame, outside the frame, on the screen?
What is a 3D standard and how can it be calculated?

These questions and more are all very real questions that must be understood in order to make good and impactful 3D images/video. I have written a book on the subject. The text is complete but I need time to finish the illustrations and drawings. I would love to teach indie film makers these things...

If 3D has a future I think it will hinge upon the glasses free tv sets that are now being developed. 3D TV that does not require glasses. Most of the systems being developed use a lenticular lens over the screen which refracts the left and right image to the left and right eye, thus creating the 3D sensation without glasses. The key for these tvs to work is having 4K monitors that are sharp and also devising a way to have the most number of viewing zones in the room to watch the 3D movie from. The problem with lenticulars is that if you move horizontally you will pass from one viewing zone to another which will make the video look like it shifted.... Did you ever look at a 3D poster that uses a lenticular lens or a Blu-ray box for a 3D movie? The lenticular lens is what directs the left and right image to your left and right eye but, next time you get a chance to look at one, notice that if you move from side to side, the image breaks or seems to shift.....

Anyway, 3D glasses-free tvs are on the way. it might be a time when indie film makers can have a real shot at distribution that pays. Streaming providers will be screaming for content!! but not shitty content. The 3D must be good... Nobody wants to risk destroying the market by flooding it with crappy 3D.
