I’ve been reading volume four of Proust’s Selected Letters, translated into English by Joanna Kilmartin. I liked this passage from a letter to a Madame Greffulje–
“When you refused me once before, you gave me a very lame excuse, namely, that a photograph immobilizes and arrests a woman’s beauty. But isn’t that precisely the point to immobilize, or rather, immortalize, a momentary radiance? A photograph is the effigy of eternal youth.”
