Whether you’re shooting photography or video, film or digital, exposure generally boils down to three elements in your camera. ISO, aperture and shutter speed. All three of these things will affect your exposure, how bright the image is. But each will also change how the final image appears on the camera. Aperture changes your depth of field. Shutter speed changes motion blur. ISO determines the amount of noise you get.
There are differences in how you might approach certain problems when it comes to shooting video vs stills, though. We may be limited by technical issues, such as flash sync speed for photography. Or the 180° shutter rule for video. So, in this video, filmmaker Caleb Pike talks us through what each does, and how we can use them to our advantage to get the results we want.
