Coincidentally, i was asked recently to take pictures of Scrooge and Tiny Tim around town for a production of "Scrooge the Musical". The pictures were to be used for any media work, and one of mine is supposed to show up in the local paper with an article on the play (i hope :-))
The above picture is from a few that was done in a local cemetary. I believe we were all respectful of our surroundings. It also occurred to me that Christmas Carol and the story of Scrooge is respectful in its own way regarding the meaning of life.
It also occurred to me that any souls at the cemetary would hopefully be more amused at our antics than anything else. I do like Mike Cash's idea of leaving flowers as a token of our respect.
What did i learn about taking cemetary pics. Well during the day, there was enough light for my K20D and a f2.8 lens to keep up. But there was a miscommunication about which cemetary we were going to and so it got darker than i wished, forcing me to change to my "fast" 50 at f1.7 and 3200 ISO. They didn't want flash. (cleaning up the noise with a plugin caused the plastic looking skin on the actor) My big mistake was that the director gave me a ride to the cemetary and i forgot to take my tripod along. With a tripod, i could have slowed the shutter down enabling a lower ISO
I don't know if this will affect your fashion shoot, but i found BW looked a lot better for the cemetary shots than color.
