Last fall, Heather and I had a frustrating conversation where I tried to explain f-stops and shutter speed. I wish I had heard about this simulator then! This is a fun way to explore what camera settings do to an image. In order to see what the different settings do to an image, you have to click the “snap photo” button, which can make the learning a little more difficult, but I love that it simulates what you actually see in an SLR viewfinder. If you are a visual person, this Flash app explains depth of field, aperture and shutter speed in a non-geeky, highly visual way.
