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, https://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.

<p>Hello. I realize no one's commented since 2015, but I was wondering if you have to use an inkjet printer for creating a lenticular image. What about a photo printing service like Photobucket or Shutterfly? </p>
<p>Just FYI, the Bogen Manfrotto 357 works great, and is about half the price. </p>
<p>If it works for you that's great. But I don't think Manfrotto357 has the capability to control the camera displacement, i.e. the distance between pictures. We have come up with a automated solution. It is a dolly that has the control panel for adjusting the distance between each shot and the speed, check it out, www.3dependable.com.</p>
<p>So you are saying your dolly is only about $120 then? (You don't display your prices, which is always suspect and indicative of pre-internet era companies that distrust the medium.)<br><br>Of course, creating the images in the Manfrotto 357 can be done as quickly as your dolly, or even more quickly. The length of the slide is approximately the same as the distance between the pupils of adults, or just slightly wider for a slightly exaggerated depth. Adding a shim can shorten that distance and make it more shallow.<br><br>If someone wants to take photos further apart, say to enhance the 3D of a deep landscape, then the LONG bar for the Manfrotto 357 is about $90 and includes a MM scale/ruler. I found one here that shows the length and scale: </p><p><a href="http://www.bhphotovideo.com/c/product/241158-REG/Manfrotto_357PLONG_357LONG_Pro_Video_Quick.html" rel="nofollow">http://www.bhphotovideo.com/c/product/241158-REG/M...</a></p><p>Naturally, even a MM scale/ruler on a standard Manfrotto 357 will achieve the desired result, and a table of distances from the camera and the speed to the distance the camera must move can be easily and quickly made. Or a smartphone tablet app. Or, simply a spreadsheet with the formula embedded. There are many ways to give the photographer the needed separation, if it is needed at all. </p><p>Trial and error experimentation will give most photographers everything they need to successfully create stereographic images sufficient for lenticular imaging.</p>
<p>would this method work as a flip lenticular too? </p>
<p>Yes, this method works for flip lenticular. But flip lenticular requires much higher precision. You should conduct a pitch test to get the true line density of the lens. For example, if your lens is 40lpi but you found that it is actually 40.05 lpi, then you will make 4 layer of image 1, and 4 image of image 2 with totally 8 layers. 8 x 40.05 = 320.4. Resize your Photoshop file to 320.4 dpi and then use the procedures described in the tutorial.</p>
<p>Cool tutorial. Why do you suggest glossy paper?</p>
<p>You don't have to use glossy paper. But definitely you cannot use plain paper because the ink dots will spread to a larger area and that will affect the precision. I suggested gloss paper because the ink dots will be more precise. You can also use high quality matte paper meant for inkjet, such as the one sold by Epson.</p>
Thank you for posting this! I got an idea and you kindly put all the resources right here! I'll tell you what I do when I do it, thank you so much!
<p>i want a photo that has five images that shift from one side of the room to the next.... all images will be the same except for the position of the heads... every head in the photo will turn as if following you around the room...... any info on that trick?</p>
Hi, <br>I was wondering how do you draw the mask? <br>I don't know how you draw the 9 black stripes in photoshop? <br>I you could help me out, it would be fantastic. <br>Thanks
<p>you can try this link</p><p>http://www.webdesignviews.com/2011/11/how-to-create-repeating-stripe-patterns-in-photoshop/</p>
Hey, <br>Thanks for the great instructable! <br>I was thinking of purchasing this guys kit? <br>What do you think? It is quite $$$. <br>http://3dphotopro.com/ <br> <br> <br> <br>
3dphotopro is run by Igor Kurchavov&nbsp;who is also a master of lenticular printing. I respect Igor for all his work but I don't know how good his kit is. You should contact Igor through his email link on his site. Igor is a nice guy.<br> <br> By the way, we have posted more 3D lenticular printing tutorials on our site since the last post. Check them out, <a href="http://www.vicgi.com/lenticular-tutorials.html" rel="nofollow">3D Lenticular Tutorials</a>.
