Camera Exposure Simulator

Are you trying to understand the "exposure triangle"?  Canon has developed an online interactive camera exposure simulator that allows users to move sliders which control aperture, shutter speed, and ISO to create the desired exposure and effect. Any brand of camera follows these principles, as long as there are  manual control features available.

There is a written explanation for each slider's use and its affect on the final image. You can experiment in aperture priority, shutter priority, or full manual modes.
