Thanks for the comments Martina, the highlights & shadows were a real challenge! The square crop was suggested by the shot where the nice framing was already in the picture. But yes, I once owned a brownie so I like square crops.
A Kodak Brownie was an old Point-and-Shoot - it gave square pictures.
@paynekj still occasionally takes pictures with one, but film is hard these days.
@richy, thank you very much, you are too kind.
