Most photos are able to be Parallel
Viewed. To Parallel View,
look into the distance, "through" the images
until they become one. It takes a while to force the eyes into focus,
and usually takes considerable practice. It may be helpful to use a
viewer to assist, such as one of the viewers from Loreo.
Some of the photos are displayed for Cross-Eyed
viewing. This can be free-viewed by going cross-eyed so that the left
eye is looking at the right image, and the right eye is looking at the
left image. Then you need to force the eyes to focus. Again, it
requires a bit of practice.
A small number of photos are provided as red-cyan anaglyphs. To view
these, you will need a pair of red-cyan glasses.
old friend, Daniel Large, kindly gave me this Pocket Rotoscope which
he'd acquired. It comes complete with 12 images from the "Actors and
Actresses" series, plus an extra photo of South Brisbane Town Hall. It
dates back to circa 1905.
