Was surprised when I was talking to Gerry Lamarre a very successful wild life photographer here in Washington State to learn that he only shoots film nothing is digital. He was saying as a complete lab setup at his location so I guess it makes since. He was saying that in large poster size prints can not get the color or quality from digital than you can from film.
here is a link to his website if anybody wants to check out his work.
