Photographic plate in chemistry
WebThe thickness of the trace of a light beam which activates a photographic plate is finite, and this is a restriction, therefore, on the interpretation of an image. The hair-line of a measuring instrument, the interval between two definite marks, the breadth of the needle of a galvanometer, all lead to inaccuracy in measurement. WebPhotographic plates face significant structural and chemical challenges unique to their make-up. There are two types of photographic glass plates; collodion wet plates and gelatin dry plates. Structurally, collodion wet plates are held together with a specific type of emulsion , made using a silver halide mixture in gelatin.

February 26, 1896, was an overcast day in Paris — and that presented a problem for French physicist Antoine Henri Becquerel. Becquerel was hoping to demonstrate a link between minerals that glow when exposed to strong light and a new type of electromagnetic radiation called X-rays. The weather thwarted this experiment — but ...
WebPhotographic plates were copper faced with silver, polished with flannel and rottenstone, taken to the dark room to be sensitized (coated with thin layers of bromine and iodine). The coated plate was then put in a plateholder and exposed in a camera.
