Genuine stereo pair88%
The two photographs contain the viewpoint difference needed to produce genuine depth.
- Depth spread
- 3px
- The range of horizontal difference between the two views. More spread generally means more depth; 0–1 px usually indicates a monoview.
- Match
- 91%
- 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.
Published by E. & H. T. Anthony & Co., New York, this stereoview is captioned “The Army of the Potomac,” looking up Pennsylvania Avenue from the Treasury Buildings in Washington. The printed label identifies “Maj. Gen. Wright and Staff and 6th Army Corps passing in review,” beneath a heading for the Grand Review of Grant and Sherman’s armies on 23 and 24 May 1865. Mounted officers precede close ranks of troops along the broad avenue, with spectators gathered beside awning-fronted buildings and beneath the trees. The paired sepia-toned photographs occupy an orange-red mount lettered “The War for the Union” and “Photographic History,” accompanied by a pale green publisher’s label numbered 3316.
