My sister recently had a wedding, and I wanted to do something special for her wedding that few, if any people had. What could this be?
Obviously the most important thing you can take away from a wedding are the memories. Memories, however, fade with time, and you need photos to keep them fresh. Photos on the other hand are bland, 2D pieces of paper. Often the background merges with the foreground, details are missed, etc.
How awesome would it be, I thought, to capture her wedding in full 3D? The concept *seemed* easy enough, but how to go about it in a pinch with minimal cost?
This eventually lead to one of the methods I will show in this instructable where I created her wedding images in full 3D. It turned out beautifully, and I sent along with the cards an antique stereoscopic viewer. But the first question to be asked is, how is it that you make something 3D?
Simply put, you need two different, though similar images to be viewed by each eyeball. If you only have one eye, I'm sorry, but this instructable is not for you... This brings us to the first step. AKA, "Free Viewing."

Free Viewing is, simply put, seeing a 2D image as 3D without the use of glasses, lenses, etc.
To "Free View"you will create two images laying them side-by-side in order to see them simultaneously. You will have the image for the right eye on the left side, and vice versa. The end result is that when you cross your eyes to "merge"the two images, you will end up with a 3Dimage.
Let's put this in practice. I will create a 3Dimage here using nothing but text. You can even cut and paste this into a word processor if you would like:
Now, if you're able to cross your eyes until the images line up, you will see a special message raised out of these letters. If you can do this, you've already mastered free viewing!
This is the same concept that was used to create those "magic eye" posters that were a fad in the 90's, except that where in the "magic eye" you were actually forcing your eyes to "uncross" here you're purposely crossing them.
Note that it's normal to feel a bit of eye strain, and to have blurry vision when you do this a lot in the beginning. Don't worry, no permanent damage is being done. Instead, you're forcing your eyes to use muscles they don't normally use, and eventually those muscles, like anything else, will become stronger. It will become easier to focus the more you do it. (Being fascinated with it, I can now Free View in a split second, and return to normal view with no problems.)
So let's look at why the above text appears 3D.
What I've done here is taken my secret message, and "shifted" those letters ever so slightly to the left (by deleting and adding spaces). When your eyes cross, your right eye is seeing those letters shifted, while the left eye isn't. Your brain translates this into 3D space. To see why this works, close your right eye, and hold your finger a few inches from your monitor, and cover a specific spot. Then switch, closing your left eye and opening your right eye, and you'll see that your finger appears to have shifted to the left. We're simply duplicating this phenomenon.
I'll be spending a good amount of time on Free Viewing prior to moving on to other things. It's important to understand WHY 3D works so as to be able to understand new and different ways to play with it.
