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
- 11px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 62%
- 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.
A green-mount stereoview from Pollock & Boyden’s “Views of the Black Hills” series. A man wearing a dark hat sits on a steep rock outcrop at the right, above a horse-drawn carriage in a clearing below. Bare deciduous trunks rise among conifers, with a rocky ridge extending across the distance. The seated figure and small carriage give scale to the surrounding terrain.
The front margins read “VIEWS OF THE BLACK HILLS.” and “PUBLISHED BY POLLOCK & BOYDEN.” The ornamental reverse imprint identifies the firm as “Portrait and View Artists,” at “COR. LEE & SHERMAN STS., DEADWOOD, D. T.” Deadwood is the publisher’s address; the card does not identify the scene as a view of that town.
The series heading establishes the Black Hills subject, but neither side supplies an individual view title or a legible publisher’s view number. The particular ridge, the seated man, and the carriage occupants remain unidentified. A pencil notation on the reverse appears to read “C 424”; it provides no descriptive identification. No date is printed. The supplied dimensions are 6.98 × 4.53 inches (177.4 × 115.2 mm).
A short surface crease affects the lower right mount corner, outside the photographs, and small reddish marks appear on the reverse. The photographs are otherwise clean and the card sound.
