Genuine stereo pair97%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- 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
- 61%
- 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.
Issued by Whitney’s Gallery, St. Paul, this stereoview bears the series heading “Gems of Minnesota Scenery” and the caption “Ox Carts, from Pembina, on Red River, 600 miles north of St. Paul.” A small group, several wearing hats, sits on ground coverings among high-wheeled wooden carts, one bearing a covered load, with open grassland and a distant tree line beyond. The paired sepia-toned photographs are mounted on a yellow card with rounded corners; light edge rubbing and scattered surface marks are visible.
