Round 2. #stereoscope#magiceye 1. Free-viewing. Try to defocus your eyes so that they look straight ahead, with lines of sight parallel, as if viewing MagicEye photos. You may see 3 images; if so concentrate on the central image, which should appear in 3D. This method is easiest for smaller images, say less than 120mm width..
2. Cross eyed viewing is a variation on free-viewing where the images are deliberately transposed right to left and left to right. Raising a finger halfway between the image and your eyes then focusing on the tip of your finger will cross your eyes. The images will be out of focus so if you then move your finger towards the images concentrating on the finger tip the images can be brought into focus and merge.
