Stereo analysis

Genuine stereo pair97%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 6px
- 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
- 2px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
An elevated view over the village of Mackinac, Michigan, with wheeled cannon, timber planking, and the fort’s stone parapet in the foreground. Below, a straight street runs through closely spaced houses and larger buildings toward the waterfront. A steamer lies beyond the roofs, with a low shoreline across the water.
The right-hand image carries the negative caption “1801 Village of Mackinac Mich., from Fort.” The yellow mount is lettered “Mackinac Island, Mich.” and bears the imprint of Webster & Albee, publishers, Rochester, New York. Together, caption and mount identify the setting as the village seen from Fort Mackinac. The photographer and date are not stated.
The reverse bears the blue collection stamp of Emily & Hayward Madden, dated “JUN 24'67,” with handwritten source and cost entries that are only partly legible. This is a collecting-history mark, not a date for the photograph. A faint pencil notation near the upper-right edge cannot be read reliably.
Some foxing is visible in the pale sky areas, with a small surface chip at the upper-left mount corner, clear of the photograph. Otherwise sound, with clear architectural and foreground detail.
