Photography

This is not just an ordinary picture; it's a stereogram. If you position your eyes correctly, you'll be able to see a virtual 3D image of the object.

Here are the steps to see the virtual 3D image (I've done it myself):
1. Move both eyes towards the bridge of your nose at the same time.
2. You'll see an image of four women.
3. Adjust your eyes so that two of the four women merge into one in the center (at this point, the image will be very blurry because your eyes are not focused on the object).
4. You'll need to adjust your focus until your eyes correctly align with the center image (this is the crucial step).
Good luck! At first, your eyes might cross a little, but once you see the virtual image, you'll be amazed.
