the chemicals were given time to evaporate, the glass plate would be
sensitized by being immersed -- in darkness -- in a bath solution. Placed in

positioned and focused by the other photographer. Exposure of the plate and
development of the photograph had to be completed within minutes; then the
exposed plate was rushed to the darkroom wagon for developing. Each fragile
glass plate had to be treated with great care after development -- a
difficult task on a battlefield. |
