Experiments
During the 1870s photographers used the common wet-plate, which required a lot of on-the-spot preparation for immediate exposure. Although not a new idea, photography was still in its early stages of experimentation. Berkeley experimented with the pre-coated, semi-dry collodian plates which were commercially available at that time. He discovered that with the addition of sulfite to Samman's developing solution, in order to absorb the sulphur dioxide, which was given off by the chemical dithionite, that dithionite was no longer required in the developing process. Berkeley published his discovery in 1881.

Famous quotes containing the word experiments:
“A country survives its legislation. That truth should not comfort the conservative nor depress the radical. For it means that public policy can enlarge its scope and increase its audacity, can try big experiments without trembling too much over the result. This nation could enter upon the most radical experiments and could afford to fail in them.”
—Walter Lippmann (1889–1974)
“My experiments did not turn out quite like yours, Henry. But science, like love, has her little surprises.”
—William Hurlbut (1883–?)
“The trouble with tea is that originally it was quite a good drink. So a group of the most eminent British scientists put their heads together, and made complicated biological experiments to find a way of spoiling it. To the eternal glory of British science their labour bore fruit.”
—George Mikes (b. 1912)
