Throughout the past month, we’ve tackled the exposure triangle—the critical way to get properly exposed photos and videos. Remember your camera and lens have three essential controls that affect how much light comes into the camera: the aperture or opening of the lens, the shutter speed (how long the shutter opens), and the ISO (the sensitivity of your sensor).
But a problem as tough as exposure can still be hard to crack. What happens when you can’t get more light into the camera and the shot is dark? How about when you want shallow depth of field and the shot is overexposed? Sometimes you have to look past the camera and make external changes to get the results you want.
