VIEWING STEREOSCOPIC PAIRS |
|
PRINTS The viewer is nowadays made for 12x15cm (4"x6") prints, however old ones allows larger prints to be watched. On these, distance between lens and print can be set. They also can view slides. A viewer can easily be made using two magnifying glasses and watching 4,5x6 cm (1-3/4x2-1/2") prints. Such glasses will be with lenses of 66mm focal length, which is 15 dioptries. Those already using glasses for near objects will have to add it to their usual glasses. |

BUILT a VIEWER
Fix each viewer next to the other. I have personally removed the white plastic diffusing plate, and use it facing a white board, or a computer screen with a white image. Laptop computers are great as lighting table!

|
LEFT / RIGHT Do not worry to know which is right view, and which is the left view: just look at the viewer, and if inverse, you will see it obviously. |

I put on the slides a red mark for the left side, and a green mark for the right side, just as port and starboard lights on boats. |
