Now we start working on the images, so fire up Photoshop or whatever program you use, and open your 2 images.(If you want to adjust your images before you start working on them, make sure you do the same layer/color adjustments on both images.)First we will edit the left_eye photo. Select that image, and then change it to grayscale by going to ImageModeGrayscale. Then change it back to RGB.Next, change the right_eye photo to grayscale, but dont change it back to RGB mode.
