I will talk you through how to turn a digital image into a 3D one! GIMP is an easy to use powerful free image editing software. You can use Photoshop or any app that lets you edit and recolour you image using layers.
To complete this tutorial, you need to have the latest version of GIMP installed and image to work with (images where the foreground contrasts with the background work best) and a pair of 3D specs.
1. Open up you image in GIMP.
Note: Make sure you can see the layers menu, if not go to MENU-WINDOWS-DOCKABLE DIALOGS-LAYERS move it to the right hand side of the screen for easy access.
2. Duplicate your image so you have two layers - click on the 'duplicate icon, two small squares overlapping, at the bottom of layers panel next to the green up/down arrows.
3. Select each layer then COLORS - DESATURATE. Make sure you have the 'eye' icon selected to see each layer.
4. Select the top image layer and turn off the bottom image layer eye icon.
5. COLORS - COLOR BALANCE move the top slider towards cyan so it reads -100, we want to make the blue a bit richer so move the middle slider towards Magenta -50.
6. Turn of the blued top layer eye icon and turn on the bottom layer eye icon. The image should still be black and white if not repeat step 3
7. COLORS - COLOR BALANCE move the middle slider towards magenta so it reads -100, again we want to make the colour a bit richer so move the bottom slider towards Yellow so the number reads -59.
Now here comes the exciting bit!
8. Turn both eye icons on, select the 'move' tool (it looks like a blue cross) from the TOOLBOX palette it should be open, if not go to MENU-WINDOWS-DOCKABLE DIALOGS-TOOLS
9. Select and move your top blue layer to the left slightly - 3 or 5 millimetres - we are trying to recreate the space between your right and left eyes!
10. Put your 3D specs on.
11. Make sure both layer 'eye' icons are showing then move the opacity slider of the BLUE top layer, in the LAYERS menu to about 48.3
12. With your glasses on you should be able to start seeing the 3D effect. You might have to revisit steps 5 and 7 and reapply with cyan and magenta sliders so the colours are richer and brighter. You might have to slightly adjust the top blue image back or forth to get the desired effect! Enlarge your image VIEW-ZOOM- 200% it will look great!
13. Save your work
14. Your image will probaly look best on a monitor or as a high quality colour print.
You can purchase 3D glasses from Amazon or make your own out of card or recycle some old specs!
