Lenticular pictures are specially crafted to show one image when viewed from the left and another image when viewed from the right. Some lenticular pictures are covered with a plastic sheet made up of thin vertical prisms, but it is possible to make your own lenticular picture with a few folds. Shaped like an accordion, folded lenticular pictures are usually displayed in deep picture frames to accommodate the creased photographs.
Select two pictures of the same size and orientation. It is advised that both pictures are related to each other in some way. For instance, you could use two pictures of your backyard in different seasons, or two pictures of your child at different ages.
Use a ruler to measure the top or bottom edges of the pictures. Divide this number by 10 to obtain your strip interval. For instance, let's say your images are 8 inches wide. You would divide that number by 10 and arrive at a strip interval of 0.8 inches.
Turn the first image face down and line up the ruler at the top edge. Make a light pencil mark after each strip interval. Using the example, make a mark after every 0.8 inches. Do the same for the bottom edge of the photograph.
Connect the corresponding top and bottom marks with light vertical lines. The goal is to have nine equally spaced vertical lines on the back of your photograph, thereby splitting the image into 10 equal strips. Lightly label the strips on each photograph one through 10, working from right to left.
Make nine equally spaced (0.8 inches) vertical lines on the back of your second photograph. Label the strips one through 10, working from right to left.
Cut each photograph along the pencil lines with sharp scissors. You will end up with 20 photograph strips.
Position the strips face down in an alternating fashion. More specifically, lay down Strip 1 from the first photograph, followed by Strip 1 of the second, followed by Strip 2 of the first, followed by Strip 2 of the second, and so on.
Tape the strip edges together using invisible tape. Make sure that the edges are vertically aligned and in the correct order before taping.
Turn your new lenticular image over. Fold it into an accordion shape, creasing where the strips meet, and insert your image into the picture frame.
You can use photo-editing software to split your pictures and combine them into one. Print off your new lenticular picture on photo paper and fold where the strips meet. Alternatively, you can use a freeware photo-splitting software called "Splitz." Check out the Resources section below for a link.
Make sure you have copies made of your pictures before you take scissors to them.
