Photo was discovered in the Neill family photos. The reverse of the photo has the words written in pencil "Oregon Express." Maybe a train line? |
| Research Note | Daguerreotype Photo
According to the encyclopedia, the daguerreotype is an early type of photograph, developed by Louis Daguerre, in which the image is exposed directly onto a mirror-polished surface of silver bearing a coating of silver halide particles deposited by iodine vapor. In later developments bromine and chlorine vapors were also used, resulting in shorter exposure times. The daguerreotype is a negative image, but the mirrored surface of the metal plate reflects the image and makes it appear positive in the proper light. Thus, daguerreotype is a direct photographic process without the capacity for duplication. While the daguerreotype was not the first photographic process to be invented, earlier processes required hours for successful exposure, which made daguerreotype the first commercially viable photographic process and the first to permanently record and fix an image with exposure time compatible with portrait photography. |
