DIY- Lenticular Printing

Create a new document in your photo editing program, then open the two photos you wish to use. These photos should be of equal height and width so they can seamlessly shift into each other without the distortions caused by resizing. Crop the larger of your two photos, if necessary, so that they are equal. The height of photo editing document should be equal to the height of the two photos, and the width of the document should be equal to the sum of their widths (alternatively, if you wish to make your lenticular photo change as the eye moves vertically rather than horizontally, make the document's width equal to the photos widths, and its height equal to the sum of their widths.)

Calculate the number of sections you want to take from your photos. The sections from the two photos will alternate in your photo document. The more sections you take from each photo, the greater the illusion of change that your print will produce. Make sure that the width and height of each section is even. Sections of 5 to 10 percent of the size of the photos are an ideal size for making the completed product create a successful illusion without making later steps excessively complicated.

Select the leftmost (or topmost) section of your first photo, and copy it. Paste it into the leftmost (or topmost) section of your document. Repeat this with the other photo, and alternate the sections of the two photos along the document going from left to right (or up to down.)

Load your printer with cardstock or another thick paper. Print your completed document.

Fold your print. This should be done with an accordion fold, so that the sections of the two different photos are folded to face each other. When you are finished folding, these sections will point in opposite directions, and you will be able to see a different photo depending on which direction you view the print from.
