Stereo analysis
AnalyzedVerdict
Camera moved / alignment issue75%
The pair does not align reliably enough for a trustworthy depth reading; scan skew can also contribute.
- 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
- 96%
- 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
- 5px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.

The paired, arched-top photographs are warm brown in tone and mounted on a yellow card with rounded corners. The printed label identifies the view as No. 131 under “Silver Mining in Colorado,” with “Galena” included in the caption.
