The original photo that this is recreating was found on a restaurant wall, and is of unknown age or origin, but probably sometime after 1870. Looks like it might have been 1/2 of a stereo.

I?m attaching two images ? the ANA, and an animated gif (made in SPM). 

The gif illustrates something puzzling to me. I?ve taken quite a few photos of this spot in an attempt to get the exact spot where the original was taken. The footing is loose, volcanic conglomerate, and the surface is steep and rounded. Some of the rocks on top have been rolled off, but there are three rocks facing the camera that stay in the same position between photos. But the perspective changes between photos. 

Could the differences between photos be just because of lens differences? I?ve shot current photos with several different cameras, and they match each other pretty well, but not to the original.

If the original camera had shifts and tilts, that might explain it. I can manipulate the current image in Photoshop to get a closer match, but that?s cheating.

Any thoughts?
