Stereo analysis
AnalyzedVerdict
Genuine stereo pair97%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 9px
- 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
- 1px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
Stereoview of the weave room at Langdon Mills, Manchester, New Hampshire. The front is captioned “Weave room, Langdon Mills.” beneath the series heading “Manchester Views.” The paired photographs are mounted on an orange card with a plain pink reverse.
The camera looks down a central aisle between closely packed looms. Broad lengths of pale cloth lie across the foreground machinery, where rollers, wheels and gearing are clearly visible. Repeated columns and ceiling beams extend toward the far wall; several workers stand among the looms farther into the room.
The reverse bears the handwritten notation “No. 44” and a name that appears to read “Daggett.” No corresponding number is visible on the front, so the verso number cannot be securely identified as a publisher’s view number. The name alone does not establish a maker or ownership history. No printed photographer’s imprint or date is present.
A small dark mark is visible in the ceiling area of the left image; otherwise clean and sound.
