What would you shoot if you were loaned a Hasselblad H4D-40? Recently, I had the opportunity to shoot with one. Having been a medium format film shooter back in college, using this camera seemed almost like I was coming back home. To see just what it could do, I put it to the test in a natural-light studio, against a medium format film camera.

The aperture of the lens controls the amount of light that passes through on its way to the camera's sensor or film plane. A camera's aperture is also commonly called its f-stop, though 'f-stop' technically refers to the diameter of the opening created by internal adjustable blades, rather than the entire mechanism.

You've probably heard of the term ISO before. But do you know what it means? If someone told you that you need to raise your ISO settings to compensate for the diminished light, would you know what they're talking about? If you don't know, here is a quick guide, straight from the EDU Advantage Team.

When I first began studying photography, I was taught that there were two types of photographers: collectors and voyeurs. I remember being immediately drawn to photographs that fell under the latter category. The photos of Cartier-Bresson, with their ability to capture subjects and environments interacting so harmoniously, were mesmerizing. I too wanted to know how to create "The Decisive-Moment."
