In this thread you may only post 3D pictures.
There are 2 types of 3D photos:
Stereograms are those shots where you have 2 similar pictures side by side, when you cross your eyes a third picture appears in the middle, if you can focus on the third image it will be in 3D! These are great because with a little practice anyone can view them and no special software or equipment is required.
Example of a stereogram, taken at the end of Diez Vistas:
An anaglyph is a stereogram that has been processed by special software, one image is shifted to the blue spectrum and one image is shifted to the red spectrum. The photos are then overlaid on top of eachother and can be viewed by anyone who has special 3D glasses like you used to get with the 3D comic books when you were growing up. These are great because it takes no effort or practice to view them.
Example of an anaglyph made from the previous photo:
I will now reveal my TOP-SECRET, classified techniques for taking 3D pictures. You all must swear to take these secrets to the grave.
Step 1: Find a scene that will look cool in 3D. It must be a still scene like a building or a mailbox, not a moving scene like an intersection or a flying bird. It should also have an obvious foreground and background to make the 3D effect stand out. It is OK to have multiple depths of field, such as a person standing in front of a group of trees with a mountain in the background. (3 depths of field)
Step 2: Set your focus to infinity, the whole shot should be "in focus" if you use a cheap point and shoot camera like I do, this step is fairly redundant...
Step 3: Using the "viewfinder" on your camera and not the LCD on the back frame your shot as you would like it and take the picture with the viewfinder on your left eye.
Step 4: Here is the magic: Don't move your head, slide the camera over to your right eye and take the SAME shot with the SAME framing.
Step 5: When you get home load up both pictures in your favorite photo editing software, crop the pictures so they are framed EXACTLY the same and the main subject in your photo is at the same "height" in both shots. Copy both photo's into one wide photo and leave a small white or black line between the shots to make it easier for your brain to sort everything out when you are viewing the 3D picture.
Your done! It really is that easy! If you want to process your shots into anaglyphs you can use this free software: http://www.callipygian.com/3D/
I wont go into details on how to use it as there is a good set of instructions on the website.
Now everyone go out, climb a mountain and take some 3D pictures. Then come back here and post them up for the rest of us to see. I expect results by noon tomorrow! (kidding)
