English: A combination photo / engraving (photo with backdrop replaced by engraving) of US Army Signal Corps personnel training with Heliograph ca July 1898 while waiting to be sent to Cuba for the Spanish-American War. From "With the Waiting Army" by Irving Bacheller, July 1898, "The Cosmopolitan", page 316. This is a crop of the bottom figure, which is titled: Signaling with the Heliograph. Note the crossed-flags badge of the Signal Corps on their sleeves. From the accompanying text, this could have been from the encampment at Chickamauga, or Tampa

| 출처 | personally scanned this in the USA from an original of page 316 of the July 1898 issue of "The Cosmopolitan", which I believe was a US publication (http://en.wikipedia.org/wiki/Cosmopolitan_(magazine)), and the article this is in: "With The Waiting Army" by Irving Bacheller (I think Addison Irving Bacheller, american journalist and fiction writer, died 2/24/1950). This is the RHS of the photograph titled" Signalling with the Heliograph |
| 저자 | I, Wikimedia user MacChess, personally scanned it, in the USA. I did crop it and clone out a couple of white spots. |
| 다른 버전 | Image:AmericanHelio1898.jpg is a version of this that has been low-pass filtered to blur out the engraving background and the half-tones on the photographic regions. Image:Heliogram US Army 1898 crop.jpg is a slightly broader crop (more of the original image) |
The dots in the background are not half-tones, but manual engraving. If you want a version where low-pass filtering has been used to give this more of a photo-realistic look, then Image:AmericanHelio1898.jpg is the version you want.
