Stereo analysis
AnalyzedVerdict
Camera moved / alignment issue70%
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
- 87%
- 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
- 4px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
A narrow stream runs beneath large angular boulders in a densely wooded gorge. Exposed rock faces rise through the undergrowth, with tall conifers standing along the upper slopes. The paired photographs look down into the channel; no people or buildings are visible.
The green mount bears the series heading “VIEWS OF THE BLACK HILLS” and identifies Pollock & Boyden as publishers. Their ornamental reverse imprint describes the firm as “Portrait and View Artists” at the corner of Lee and Sherman Streets, Deadwood, Dakota Territory. This establishes the publisher and studio address, not a precise location for the gorge.
A faint but legible pencil caption on the reverse reads “Dells of Black Hills,” supplying the title used here. There is no printed individual view title or numbered reverse catalogue. The Black Hills identification is supported by both the inscription and the printed series heading, but the particular gorge and stream remain unidentified. The card is undated.
The supplied dimensions are 6.98 × 4.55 inches (177.4 × 115.5 mm). Conspicuous dark linear marks cross the photographs, especially the right-hand image, and there is localized brown staining on the reverse. Otherwise sound.
