Stereo analysis
AnalyzedVerdict
Camera moved / alignment issue90%
The pair does not align reliably enough for a trustworthy depth reading; scan skew can also contribute.
- Depth spread
- 8px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 68%
- 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
- 8px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
Two arched photographic views show wooden buildings below a rocky outcrop at Dungeon Rock, Lynn, Massachusetts. Picket fences enclose the buildings, while stone walls divide the uneven ground beyond. Cut logs and branches lie in the foreground, behind a low wooden rail; figures stand near the gates and higher on the rocks.
The reverse carries a numbered checklist headed “Views of Lynn and Vicinity,” with a faint pencil selection mark at “31. Dungeon Rock.” The publisher’s imprint reads “PUBLISHED BY WM. T. WEBSTER,” followed by “No. 8 Exchange St., Lynn, Mass., opposite Depot.” This establishes Webster as publisher, not necessarily as photographer.
The next entry, “32. Entrance to Dungeon Rock.”, indicates a probable related pair within the larger series and merits comparison with other surviving cards. The preceding entry is “30. Lynn Beach.” The card supplies no date, and the people and individual buildings remain unidentified.
Mounted on green card, measuring 6.92 × 3.48 inches. Small patches of surface-paper loss appear at the upper left of the mount, with a localized pale blemish near the right edge of the left photograph; otherwise clean and sound.
