...The ones that require red and blue goggles are now the hardest to view -- unless, of course, I have the wrong colours, but I don't know whether I have right or wrong colours.
Okay, I tried my cardboard red/cyan goggles on some Apollo Anaglyphs and am getting weird results.
Phil Plait recommended this one:

But with the goggles on, those two craters look very steep-sided and roughly about 80 to 100 metres deep, yet the Post-Flight Apollo 14 Traverse Map (4.1 MB)
https://www.hq.nasa.gov/office/pao/History/alsj/a14/a14-usgs.jpgwith contour lines, indicates that they are much shallower. I scoured the Apollo 14 ALSJ and found no mention of the depths of the Triplet craters. This PDF without electronic text
https://www.hq.nasa.gov/alsj/a14/a14pp-021-030.PDFsays on page 23, "North Triplet crater had an original depth of about 30 m".
Looking at some Apollo and some non-Apollo anaglyphs I saw three weird effects in many of the photos -- excellent 3D, vastly over-exaggerated 3D, and no 3D at all where it should be. And sometimes a fourth effect -- a strange banding that shouldn't be there.
Now, that could be the result of my goggles (cardboard giveaways from HBO) or my eyes, my age, or poor processing, or any and all of those. In fact some of the anaglyph images looked much better in their original single-image form without the goggles, but without 3D.
Maybe I'm just being fussy. Perhaps spoilt back in the 1950s by those old hand-held 3D viewers with a gazillion two-image black-and-white or hand-coloured cards that used to be in every second-hand store and thrilled me at the age or four, or later spoilt even more at the grand old ages of 6 to 8 by the brilliant Viewmaster system with its fantastic, vibrant colour images. I got one Viewmaster reel for my seventh birthday and bought one or two more with a gift of a few shillings. They seem to have been many times better than these new-fangled anaglyphs, but maybe it was my young eyes that made them so vibrant.
H-E-L-P !!! What's going wrong? I want to see
good 3D.
