Hi everyone – just wanted to share a few resources to go along with our very brief lesson on 3D images & Photoshop. Good luck on your Anaglyph extra credit assignment!
- Using the Repousee tool to extrude 2D images into 3D space
- Using the Repousee tool to extrude text into 3D space
- Creating an Anaglyph 3D image using Photoshop (detailed)
And here’s a quick overview on the basic steps to create an anaglyph image:
- Take two photographs that are horizontally separated by about 2 inches (i.e. take a picture and the move your camera about 2 inches to the right and take another picture). Note that your subject is very important – try and have objects that exist in the foreground, mid ground and background of the image. Try and keep your closest subject about 4 feet away from the camera.
- Open up both images in Photoshop.
- Copy both images into the same document. Name the layers “left” and “right” accordingly so you don’t forget which is which!
- Put the left image on top of the right image.
- Remove the Red component from the right image. You can do this using the Image -> Adjustments -> Levels window. Select the Red channel and type the number 0 into the box that says “Output Levels” (so that it outputs from 0 to 0 in the red channel)
- Do the same thing for the left image, but remove the green and blue channels.
- Click on your left image and set the Layer Mode to “screen” – the layer mode dropdown is at the top of the Layers panel.
- Put on your glasses! It probably won’t look great the first time
You may need to adjust the position of your image to get it just right. - You may also need to desaturate your image if your subject has a lot of red or blues — you can do this by clicking on Image -> Adjustments -> Hue Saturation and dropping the saturation way down (-50 or so)
