Creating a 3D Anaglyph in GIMP

Hello, everyone!  This is my first tutorial in a program that's not blender; I am using a program called GIMP.  GIMP (GNU Image Manipulation Program) is free image editing/creating software that can be downloaded here:

In this tutorial, I will be running two different images through GIMP to form a 3D anaglyph.  I took these photos with my camera; of course, you can do the same in blender, or any other 3d software as well.  The goal is to take a picture of your subject, then move the camera over to the right a little bit and take the photo again.  Keep in mind that this is the traditional red & blue 3D, as I do not have all of the equipment to produce a new 3D image; since this is the red and blue kind, you will also lose any color you had in the image.  Just a heads up before starting this tutorial.

Start by opening up GIMP, and opening the second of the two images you took.  Next, select 'Open as Layers' and choose the first of your two photos.  On the right, there should be a Layers box; select the first layer, then at the top, under Colors, select the Colorify option and click on the red colored box.  Next click on your other layer and do the same, but this time choose the light blue colored box.  Now select your first layer again by clicking on it, and lower the opacity to about 50

If you get your 3D glasses on now, the image should be 3D.


  1. That's pretty cool, Ben! But, is there some way to do that in Blender?

  2. Yes; it'd be a lot harder then. If you're referring to the title of my blog, I think it's okay to do an occasional tutorial for another program, especially since everyone can access GIMP for free, and just about every blender user already has it. And I'd rather not change the title to 'SSimpossible's Tutorials for Blender and other software and portfolio' as it's already long enough as is, in my opinion. If you weren't referring to the title, sorry about all that. Glad you like it though. :)
