Of the 3 pictures you posted, this is the only one with any depth to it at all, but it’s inverted. Switch left and right, and it’s pretty good. I suggest you make new post with the correction.
The other two are completely devoid of a 3D effect.
Oh that’s interesting, I definitely get a depth of field with the other two, but you’re right that this one is much more pronounced. In any case, I didn’t make them. They were produced in the early 1800s by Ben Franklin, and it wouldn’t feel right to edit them (not that I have the know-how).
