BS in Geology here, discovered in field camp central Utah ‘88 that you could view topo maps without a device. Look straight ahead, kind of distance focus, and glance at the map until the images converge. I’ll try that now with this image.
I don't know. I'll be afraid it might make me crossed eyed!
Lol!


I think you absolutely NEED red/blue lenses on this shot. The photo 3D staring effect doesn’t work on these two color photos.
