I can usually converge stereoimages with no aids. I found that a 3X5 card held as a barrier between my eyes, and aligned with the space between images made convergence quite easy.

That young lady is definitely three-dimensional!!

I have the 3D app on my iPhone. I love taking 3D photos.

Nobody else in the family seems to give a rip, but I’m intrigued by capturing and viewing images in 3D.

I can usually converge stereoimages with no aids.

I place an index finger just to the side of each eye, and knudge the skin back towards my ears. That pulls the eyes enough to create a converged image in the center of the originals (you'll see three images). Shift the individual fingers up or down to fully merge the images.
