Simon Winchester has produced a well-written, wonderful little book (only about 100 pages) that examines a very different aspect of the Charles Dodgson/Lewis Carroll that most readers know. Dodgson's passion for the then-new art and science of photography during his early years at Oxford produced some remarkable photos, and this book focuses on the story behind one of them, young Alice posed as a beggar maid, in fascinating detail. No photos in the text, unfortunately, other than the one under discussion. But the book is fast to read, and well worth picking up.
