I don't really have a favorite camera. I use a Leica and Canon a lot. It depends, especially professionally, on the requirements. But my carry-around camera is a Leica.
I don't think about what camera I should use that much. I just pick up the one that looks nicest on the day.
I like having the digital camera on my smart phone, but I also like having a dedicated camera for when I want to take real pictures.
Today my passion is still black and white. Today if I have an array of cameras in front of me the one I would reach for that I would feel most comfortable with would be a 4 X 5 View camera. I was once working in a sort of soft light situation.
It's not about the equipment. Be less concerned about what kind of camera you have and more about what kind of effect you're trying to accomplish. Finding an original take is much more important than what you shoot it with.
If I have an idea I want to put in a movie, I know what camera will make that look best, and I have ideas for future projects and stuff I'd like to build for those. I think it's just part of how I work, though.
I don't use iMovie and don't use shitty little cameras to try to prove something or say something because that's a part of the process. We do it just because that's what we like to use.
I can't stress enough how unimportant the camera really is. Any brand of camera will do. For 95% of my shots, the lowest end DSLR will be just fine.
I shot 'Blue Valentine' on 16mm for the past, and for the present on the Red Camera. I feel that both formats are valid. The stories should dictate the format we shoot on. Filmmakers should have a choice.
I am not going to be dictated to by the size of the camera. I use everything from an 8 x 10 to a 35-mm. But I don't use these modern cameras which break down all the time !
