This famous photo was actually shot with two different cameras at the same time -- each from a slightly different perspective -- much as your eyes see practically everything. I am able to "see" this photo with remarkable depth perception. Here is how.
1) enlarge the photo as much as you can or hold your face very close to the screen.
2) If you wear strong eyeglasses it may help to remove them.
3) Use both eyes to fixate on the vertical line separating the two photos, then "relax" your gaze until you perceive not two but three images -- one 3D image in the middle and two flanking photos. The middle image should strike you with its depth.
4) If you have trouble seeing this optical illusion, practice just trying to see the three images and then look for the depth. If you've never done this, it's a bit of a eureka moment.* You train your eyes and brain to edit out the the two peripheral images on either side.

*The eureka moment is worth striving for, but don't do this for too long or your eyes may stay like that. I learned to do this in college where chemistry textbooks presented various molecular structures in 3D as pairs of images. Some students needed special viewers to see this effect, but I trained myself to see it without the viewer.
Here's another Bennett photo to practice on; the oars should be strikingly in 3D. Remember to enlarge the image or get real close.

The 3D effect is so striking that it's wonder that it wasn't discovered long before photography. An artist or even a scientist could have sketched any object and paired them such.
I'll keep trying but no luck as yet. Though I can remember doing a similar eye/brain trick for a different purpose, years ago. Though then as well my brain was a bit more dense than now, back then.
