The camera’s shutter and the lens’s aperture are two of the key variables in achieving a correct exposure, but what do they actually do, and how do they impact the image ?
In this tutorial we will go through the basics of shutter and aperture control so that you can use these two variables to not only control your exposure, but also to gain creative control.
Whilst the two controls affect two different aspects of the camera, they work in tandem (together with sensor speed) to control the exposure.
