Genuine stereo pair94%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 4px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 93%
- The share of usable picture detail that can be matched between the left and right views. A higher number means a more reliable comparison.
- Vertical
- 3px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
Captioned “1000 Mile Tree, Weber Canon,” this stereoview bears the imprint “Wm. H. Jackson, Photographer, Omaha, Neb.” and the series heading “Scenery of the Union Pacific Railroad.” Men in brimmed hats, several bent over long-handled tools, work along tracks curving through a rocky cutting beside a tall conifer bearing a small sign. The paired sepia-toned photographs are mounted on a yellow card with rounded corners and red lettering, with scattered spotting and light edge wear visible. The composition places the named landmark within a scene of railroad labor.
