Correspondence between Becker and his mother illustrate the prolific nature of his work connecting with commercial photographers, dealers and print sellers on Prince Albert’s behalf. His letters also refer to his own practical experiments and advancements in photography, referring to the results he hopes to achieve during summers at Osborne House, and making use of a chemistry laboratory he established there. For example, in a letter written from Osborne House on 18 March 1855, Becker writes:

Not only that the magnificent collections of the Queen and the Prince grow daily, they also have constantly used photography for the most diverse purposes, wherever they wish to have a true depiction of nature, be it the progress of the new house in Balmoral, the wounded soldiers from the Crimea or a Raphaelesque picture in Rome.
