Understanding the interaction between light, aperture, shutter, sensor and exposure when it comes to DSLR cameras can be a lot easier said than done even if you spend hours on Wikipedia, photography blogs or in class. The best way to understand it is to get out there and start taking pictures… or to use London-based animator and designer Simon Roberts’s Photography Mapped website. The interactive website explains how DSLR cameras work by giving you a test image and access to light, aperture, shutter and sensor sliders that automatically adjust an exposure meter and allow you to take a test shot to see what your image would look like if you were shooting it with a real camera. As if that wasn’t enough, he manages to take the traditional “exposure triangle,” add the much needed element of time, and still make it easier to understand than anything else you’ll read on the Internet. Learning how to really use your DSLR camera just got a lot easier.
