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
- 97%
- 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.
H. A. Doerr’s stereoview of Military Plaza, San Antonio, shows people seated and standing around cloth-covered tables and wooden benches, with wagons and low storefronts beyond. Several figures wear brimmed hats, while dishes and vessels are arranged across the tables. A storefront sign names A. Heusinger and advertises hardware, oils, and paints. The paired, arched-top photographs are mounted on orange card, bearing Doerr’s printed San Antonio photographer’s mark and the handwritten caption “Military Plaza.”
