I think the equipment you use has a real, visible influence on the character of your photography. You're going to work differently, and make different kinds of pictures, if you have to set up a view camera on a tripod than if you're Lee Friedlander with handheld 35 mm rangefinder. But fundamentally, vision is not about which camera or how many megapixels you have, it's about what you find important. It's all about ideas.
