DIY Camera Array 1: Computational Photography Primer.
DIY Camera Array 2: Computational Refocusing With Just One Camera
DIY Camera Array 3: ... TBA
This first Instructable is a primer on the field of Computational Photography, which is a new field of research that is developing extremely powerful cameras. These cameras allow the Depth of Field, the object in focus, and the position of the camera to be modified after the picture is taken. None of those things are possible with a traditional camera.
We show how to build one kind of computational camera -- a light field array. There are many other designs out there.
Imagine focusing a picture after you take it.
Imagine focusing right through fences, trees, and people.

Over the last half decade, a new field of research has developed, called Computational Photography. Computational Photography is still in the process of defining itself. As a young field, it incorporates insights from many other fields: mathematics, image processing, optics, art, visual neuroscience, and more. Central to the field is extending the capabilities of the camera. You may be surprised to learn that cameras have hardly deviated from the camera obscura (box-with-a-hole-in-it) design over the last hundred fifty years. Computational photography is, to date, the most radical re-imagining of what a camera is, and what a camera can do. Frédo Durand recently said "Computation is the new Optics" and this is probably the best field-defining phrase we've heard yet. But there is no computation without hardware.

Researchers have created many new camera designs, extending and enhancing almost every functional element of the camera. Many of these new cameras attempt to capture a richer representation of light, which is called the "light field". What is the light field? Surrounding you, now and always, is a reverberating volume of light. Rays of light bounce around you from every possible angle. Some new computational cameras attempt to capture this light field, which has the potential to give the photographer unprecedented creative control... after taking the picture.

Would you comment on what was actually wrong with the Instructable? Do I need to combine all such instructables into another 79-step monster, like the Book Scanner Instructable?

Sorry, that was just a form comment.
The project looks awesome, you just need to break it out into separate steps...doesn't have to be 79 different ones mind you.
If you do that and then republish it, you should be good to go.
Let noahw know if you have any other questions.
As you can see, the instructable consists mostly of pictures, though the admin bot is telling me to include pictures.
I'm not sure why this Instructable is causing so much trouble. I'd be happy to delete it, as well as the companion piece, and move the tutorial material to my own site.
