Some people will tell you that the gear doesn't matter. That what matters most is the person behind the lens shooting the image. I do agree that it absolutely takes more than just amazing gear to create a beautiful photograph. Composition, lighting, and emotion are all things you have to really have an EYE for. But...great gear really does help. When I started shooting weddings, I came equipped with a cropped-sensor DSLR, a terrible zoom "kit" lens, and one flash that I pointed directly at my subject at all times while indoors. Since then, we've upgraded a bit. Here is our full gear list (between two photographers).
