The Houghton Empress is a British-made plate camera from Houghton of London, a maker active in the early twentieth century. It belongs to the era of folding and stand plate cameras used before roll film became dominant.

Sales data for the Empress is extremely thin: a single recorded UK auction hammer result from 2003 stands at £141, which gives a reference point rather than a current market value. With only one data point at saleroom level, what a Houghton Empress is worth today depends heavily on condition, completeness of plate holders and lens, and buyer interest on the day, so any price quoted now would be speculative.
