It's one of our pet-peeves that so many DSLRs never make it off the Auto setting, with owners seemingly wanting a powerful point-and-shoot.

But at the same time we can understand that confronted with so many dials and buttons, would-be photographers are daunted by manual controls.

The web-based simulator lets users tinker with the lighting, distance, focal length, ISO, aperture and shutter speed -- to see how that alters the resulting image.
