What is the largest camera you have ever seen? The biggest one I have seen was in Saudi Arabia, it took up....it was 3 good size rooms. I had the chance to walk into this camera, it was used to talk very sharp photos that they used when looking for oil. Now that is was a big camera. They also had 3D cameras, 2 cameras working as one; you could see the 3d image by put these glasses on and looked at a computer screen. WOW they where cool toys. Who said money can't buy happiness?
