3D lenticular printing using Photoshop and inkjet printer

3D lenticular print is a way to present 3D effect on a flat surface.  The idea is to use a plastic sheet with many lined lenses so that light will be refracted in different angle for our left and right eyes.  When an image behind the lenticular sheet is designed in such a way that one image will be seen by the left eye and another image will be seen by the right eye a 3D effect will be rendered by our brain.

Lenticular sheet can be purchase online from microlens.com at about $5.00 per piece.  In this tutorial we assume you will use the 8" x 10" 40 LPI lenticular sheet.  We further assume that only two pictures will be taken.  If you use LPI other than 40 and if you want to take more pictures to make the final image less sensitive to horizontal head movement then please refer to the original tutorial in the 3D Lenticular Printing Tutorial section of vicgi.com

Step 1 Take two pictures with binocular disparity

Find an object of interested about 2m from the camera, then take two pictures along a straight line with the displacement between the left and right about 60mm.

Refer to the instructable on how to make a track for the camera to move horizontally, http://www.instructables.com/id/Stereo-Photography-Track-quick-and-dirty .

You can also purchase the slider bar for about $100 from http://www.stereoscopy.com/jasper/slide-bars.html.

Alternatively, just tie the camera on a die-cast model car and move it along a straight line.

If you just want to do it as an exercise, you can download the two high resolution pictures in this step.
