The Wet Collodion Process Thomas Rodger
Below are some extracts from Thomas Rodger's paper
On Collodion Calotype, |
||||||
Expose the Plate |
||||||
The Exposure "The lenses with which the accompanying pictures have been taken are German whole-plate size, and ten inches focus. With a diaphragm of two inches diameter, the plate requires to be exposed from eight to ten seconds, for a negative in summer." "If a positive on glass is desired, the plate should be only exposed for a third of the time" [and different development solution used] |
||||||
Portraiture "For portraiture, I invariably use a shady place, so chosen that the main light shall fall on one side of the subject. An awning or roof is placed about three or four feet above the sitter to prevent too much light striking directly on the head." |
