B&W 8x10 of us sitting on a blanket in the pitch black tropical night from 16,000 feet with a flash exposure of 1/10,000 second. !
Or maybe just a lucky bastard! As I said before, it's a good thing the flyover didn't happen a few minutes earlier. Coulda been compromising.Hah! You my sir, are either a liar or a gentleman!
Are those the things that used to be in newspapers years ago, what looks like a random crazed pattern has a 3-D image in it if you stare "through" it?I'm a former imagery analyst, having served in the British army, and continued as an IA after I retired. Although stereoscopy is not used as much in the digital world, it is still possible to produce digital images, called anaglyphs, by overlaying different-tinted overlapping images and looking at them on screen using glasses with red/blue or red/green lenses!
When I was a "junior" in the discipline, I was told that experienced IAs could see 3D from two overlapping images without using a stereoscope! Now I'm a lot older and wiser, I can still use this trick, which really helps when doing "spot the difference" puzzles! It's just a case of slightly crossing your eyes until you see three images, then concentrating on the one in the "middle". Any differences will appear as a fuzzy blur!
It's a funny old thing, but since I've stopped using a stereoscope, my eyesight has deteriorated a bit!I used to be able to do that sometimes Chris, but if I tried now, my eyes would probably stay crossed. !!!
I certainly remember having a headache, after long periods using the stereoscope, and these days I'm reminded of this when using my "Optivisor" magnifying head band, for long periods when modelling.
It's a b*gger getting old !

As my Dad used to say (in Welsh), "Old age doesn't come on its own!"Yep, even allowing for ageing, I've noticed the same.
In my "civvy" career, I spent many hours each day using a "dot" glass, checking half-tone negatives and prints, and rarely, if ever, got tired eyes or poor vision.
Similarly, when modelling, using the "Optivisor" and various strength magnifying glasses, my eyes were fine. But, over the last six months, I haven't used these tools, and now find I need to wear reading glasses to view the computer screen properly, and for reading, which, for the most part, I didn't need to do previously.
It is also similar to the technique for seeing aircraft in a clear blue sky, with no cloud your eyes focus a few feet in front of your face.A very similar technique! It's a matter of relaxing your eyes enough to be able to adjust the focal point!
I used to love teaching stereoscopy to student IAs, the result of them getting two images into stereo almost always resulted in shouted expletives!
Stereoscopic image of the surroundings becomes more stereo... quadro?That's what happens to my eyes, on the way back from the pub on a Saturday night !
I thought that was "uncaging the optics"!That's what happens to my eyes, on the way back from the pub on a Saturday night !
