Genuine stereo pair93%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- 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
- 89%
- 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
- 3px
- Vertical drift between matched details. Lower is better; 4 px or more can indicate camera movement, scan skew, or poor alignment.
This stereoview by H. P. Macintosh of Newburyport, Massachusetts, is captioned in ink “First Horseless Carriage.” A man in a peaked cap and buttoned coat sits in an open vehicle with four large spoked wheels on an unpaved street, before a shuttered clapboard building and a neighboring brick house. The paired arched photographs are mounted on green card printed with the photographer’s name and town. A numbered catalogue headed “Views of Newburyport and Vicinity” records the range of subjects offered by Macintosh.
