Wondering if anyone has shot birds in B&W? Specifically, I'm thinking about large birds like herons, egrets, or even gulls, since I have shot many in color with a digital camera. Always amazed at the way feathers transmit or reflect light and wondering how they would look with B&W film, like HP5 or Delta 400. Depending on conditions, I may push HP5 one stop to ISO 800. Any suggestions or examples from others greatly appreciated! Phil
