Stereo analysis

Genuine stereo pair97%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 5px
- 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
- 1px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
An elevated waterfront view with sailing vessels moored beyond a cluster of small wooden buildings. Stacked and scattered timbers fill the foreground, while several small figures stand beside the buildings and water. The vessels’ dark hulls, pale trim, tall masts and rigging are distinctly recorded.
Across the water, a fenced bank rises through paths, bare deciduous trees and evergreens to a row of substantial houses. A prominent gabled house with a broad porch overlooks the vessels. The paired views bring the foreground sheds, shipping and hillside residences into close relation.
The reverse is clearly inscribed “Canada” in pencil. A much fainter inscription above appears to read “Welland Canal,” suggesting that waterway in Ontario, although the reading merits confirmation from the original card. The particular town or reach of the canal, the vessels and the buildings remain unidentified.
The two side-by-side views are mounted on yellow card. No printed maker’s imprint or publisher’s catalogue is visible, and the photographer, publisher and date are not established. The photographs are generally clean; an irregular ring stain and surface soiling are visible on the reverse, with the card otherwise sound.
