We stayed another night at our friends home after the previous day of paintball shooting. In the evening I went outside into their garden to take some 3D photos. I used a tripod to keep the photos sharp because I had to use a slower shutter-speed as the light was getting dim.
Read this post I wrote on stereoscopic photography to learn the technique of how toview the photos in 3D: Day 146: A Midnight Stereoscopic Landscape
Editing: Photoshop, Camera Raw, Color Efex Pro.
If it is difficult to look at the photos in 3D, move yourself further away from the screen. Try again and it should be easier!
