Download and install a 3D-conversion software compatible with your computer. Software programs usually have versions for both Mac and PC systems. Some programs cater to conversions for still images, while some cater to conversions for moving images or videos.
For a do-it-yourself 3D process, the anaglyph 3D system is typically used because of its accessibility and practicality in workflow and 3D glasses used. For professional conversions, they are done in a studio or production house specializing in 2D to 3D conversions. However, this option is quite expensive and are only widely used by big movie studios.
Open your stereo images in your conversion program.
Configure the left and right images prior to the 3D conversion. Choose the "Auto Color Adjustment" function of your program for the automatic adjustment of the stereo images' color attributes. This makes the two images' colors identical to each other, which is important in creating an accurate 3D image. Next, click the "Auto Levels" function in order to adjust other image attributes such as the brightness and contrast. Finally, click the "Auto Alignment" function to correct the visual alignment of the stereo images, which is another crucial consideration in producing an accurate 3D image.
Preview your processed left and right images on the "Stereo Window." The stereo images will be shown side-by-side.
Click the "Color Anaglyph Mode" function to prepare the image for anaglyph 3D conversion, then confirm the process. Once done, view your 3D image using anaglyph 3D glasses, also known as the red-cyan glasses. You can easily make a pair yourself or buy one from an online store, vintage shop or video store.
