Anaglyph 3-D February 22, 2011

Posted by leskanturek in 3-D work, Anaglyph 3-D, Class Assignments.

You are going to create a 2-D illustration that appears in 3-D when viewed through red –blue anaglyph glasses.

How anaglyph works (From wikipedia)

“Viewing anaglyphs through appropriately colored glasses results in each eye seeing a slightly different picture. In a red-blue anaglyph, for instance, the eye covered by the red filter sees the red parts of the image as “white”, and the blue parts as “black” (with the brain providing some adaption for color); the eye covered by the blue filter perceives the opposite effect. True white or true black areas are perceived the same by each eye. The brain blends together the image it receives from each eye, and interprets the differences as being the result of different distances. This creates a normal stereograph image without requiring the viewer to cross his or her eyes.”

There are many ways of creating an 3-D anaglyph image. Jerry demonstrated taking a photo with a digital camera that takes two photos at the same time. Each photo in the pair is unique mimicking the way your eyes view an image/scene. Your two eyes are not in the exact same place right? Your left eye views an object from it’s left side and the right eye is looking at that same object a little more on the object’s right side. After Jerry downloaded his pair of photos of the class he then reassembled/layered the photos on top of each using an application (he used split MPO) to position them. One layer was filtered for red and the other layer was filtered for cyan in photoshop.

(above) Jerry’s stereo 3-D photo of the class.   I think he mentioned using a Fuji W1 3D Camera but I will confirm this.


Here is a link for a simple way to create a anaglyph image. Simplest Method of Making Anaglyph Images with Photoshop

The author in the demo is using a pair of photos but you will be using one piece of art and duplicating it to get your pair.

Above is a simple piece of line art I converted to 3-D using the step-by-step in the link.

  • I opened up my art in photoshop in RGB.
  • I duplicated the art onto a 2nd layer (label the layer left as an example)
  • I followed the instructions in the link  …“un-check the B and G check boxes” etc.
  • I moved the left layer over to my right about 5,6 hits of my right arrow key.
  • Put on your glasses and see what you got!

The image I created above “pops out”, but not really does it?  it’s pretty flat. That’s because there is no foreground or background. Look at the same image with additions to the background and after I selected the arm, and placed it on another layer. I shifted it a bit more to the right to get it more to the foreground.

Now it’s starting to look like a 3-D image right?  Your illustration, to capitalize on the 3-D effect will need an element/s in the foreground, a middleground and a background. How extreme, how subtle, etc. is where the artistry ,craft and planning comes in.

Jerry had demonstrated “skewing” an image to create depth in a selection. I’ll have more on that  shortly.

Experiment, make selections of different objects,for example a head, place it on a another layer and shift it over to make it pop out. Select a nose on the face-place it on a new layer and shift that over. see how much depth you can get in your illustration.

Google search Anaglyph 3-D images there are some very cool things out there!
