The main priority in sports photography is frozen action with no motion blur. We achieve this by using a fast shutter speed, ideally 1/1000th of a second or faster. Selecting that fast of a shutter speed at night will not allow in enough light to the sensor, so we make some changes to our ISO and aperture to maintain proper light exposure. Most of our images shot indoors or under the lights are at ISO 3200 or higher. Newer cameras and advanced editing software allow us to fix the digital noise higher ISOs bring with them, so I don’t even flinch about living in the high ISO range.
The final exposure element -- aperture -- not only allows us more light, but ensures the focus is only on our subject and provides for a shallow depth of field. This is where you get that “fall off” in focus which blurs the background. f/2.8 is considered wide-open in terms of light allowance, but also keeps the focus tack sharp on our subject and isolates away from the background to keep the viewer’s eye where the photographer wants it.
