Photography in the Canon

The Sherlock Holmes Society of London is sponsoring a seminar looking at Photography in the Canon. This worthy topic, of course, raises the question: What are the photographic references in the Canon; which stories, and what are the specific instances? Frankly, Buttons cannot think of a single one off the top of his head. He’s confident many of our members will do much better. He will, however, contemplate the question during today’s ‘pie and pint’ break.
