Summary
[edit]DescriptionStereoscopic photograph around the years 1900-1920.jpg |
English: It is not an ambrotype, but a stereoscopic photograph around the years 1900-1920. A demonstration of the way a photographic glass negative, when viewed by reflected light against a black background, appears to be a positive image
Español: Esta fotografía es una placa de vidrio estereoscópica, hacia los años 1900-1920, tipo Verascope Richard. No es un ambrotipo, pues no es un negativo de vidrio al colodión. No es una placa artesanal (como los ambrotipos verdaderos). Estamos ante una placa de vidrio al gelatino-bromuro, de producción industrializada. Era un gran error titular ese archivo "Ambrotype", pero ya se ha cambiado el título en 2023. |
