Re: 3D vision seems to come and go
I started shooting stereoscopic images around 1956 when I bought a used Stereo Realist camera and a viewer. It is my opinion that the best way to view 3-D pictures is still by an individual viewer. With a systems approach as the Realist David White company introduced there was a wave of enthusiasm. With the Polaroid method of group viewing there were headaches and fussy things to think about. I won't get into the details, but movies then used two projectors and they had to be frame by frame synched. Polarization,even current versions, cuts down lots and lots of illumination. Colors are washed out often. Some folks have suggested that the inherent difference between stereo photos and actual vision is that the eyes are used to combining accommodation ( focus) with convergence ( close angle of eyeballs with different angle for distant vision. Obviously a flat screen is always a flat screen. I have many many 50s to 80s Kodachrome photos of family and friends. I will continue it as a personal if niche like occupation. With film gone, it gets harder to employ. I have a Fuji camera and have a linked pair of Lumix GX7s. But still no great way to view. Free viewing is so so. I mastered it long ago. It does not do justice to a stereo pair in Kodak's marvelous transparency film with a high end achromatic lens viewer. ( Viewmaster was not even close. But one can only demo that in real life.) I am glad that we still have some cinema in 3-D. Pity that LG did not make even one OLED model with 3-D after about 2016 and the Epson etc projector systems are not my cup of tea. A computer size monitor will never do justice to the effect size wise ( Google orthostereo)..for reasons already touched on optically and visually... It got a bad rep and no way out of that bad rep, so it seems but calling it a fad is not right as the fad lives on like reading poetry and baking your own cakes.... But hardy followers will still keep the idea alive, as they have for decades Photo:. Parallel pai I took( 1962)near Havre de Grace MD on Susquehanna River.

A parallel pair(1962, Realist chromes). Good one to test your blosssoming skill upon. Sorry, I did not transpose for those who fail... Armed Forces Day regatta with Carole in foreground.
