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:
“Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.”
—James Conant (1893–1978)
“There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.”
—Denis Diderot (1713–1784)
“The man who invented Eskimo Pie made a million dollars, so one is told, but E.E. Cummings, whose verse has been appearing off and on for three years now, and whose experiments should not be more appalling to those interested in poetry than the experiment of surrounding ice-cream with a layer of chocolate was to those interested in soda fountains, has hardly made a dent in the doughy minds of our so-called poetry lovers.”
—John Dos Passos (1896–1970)
