To use a DSLR most effectively, you need to understand how settings like shutter speed, aperture, and ISO (light sensitivity rating) affect your photos. You can read all you want about the various things you can do, but until you actually try it out and see the results it can be hard to imagine. There are a lot of variables that contribue to your final result, and CameraSim lets you see how they all work. There’s even a spinning pinwheel in your frame so you can change your shutter speed and see what’s necessary to avoid motion blur.
The simulation is very detailed and a great way to learn what every little setting does. If you’re thinking about purchasing a DSLR but want to learn more about how it works first, you should spend a little time with CameraSim and teach yourself.
