Faster ISO

• Using a faster film speed or ISO is a good way to get action shots in low light to come out. Faster ISOs like 800, 1600 or 3200 speed will absorb more light when flashed briefly by the shutter, allowing an image shot in lower light to effectively absorb into the film's emulsion. These photos will have more grain then slower speed film, but are an effective way to get great action indoor sports shots.
  
  

Use a Tripod

• By putting the camera on a tripod, you can take photos in low light at a volleyball game with much more control. Even the steadiest hands will still shake slightly and when you need the shutter of the camera to be opened longer this will cause all the images that are captured in the photo to come out blurry. So by affixing the camera to a tripod there are three more legs that can help hold the weight of the camera perfectly still so you can concentrate on what is going on in the frame and the shutter speed of the camera itself.
  
  

Shutter Speed

• When shooting a volleyball game in low light, use a slower shutter speed so that the shutter stays open slightly longer and more light can hit the film or digital format. If you're using film to shoot, it's much more difficult to gauge when you have the right shutter speed set for the action or the light without a light meter. With a digital camera, which most people shoot with, you can experiment. Set your camera on a tripod and shoot with different ISO's and shutter speeds and pick whichever one looks best. Then proceed to shoot the rest of the volleyball game, and future volleyball games, with that.
  
  

Where You Shoot

• What you focus your camera upon is as important as any technical settings on your camera, once you have those right. A good action photographer learns to predict the action before it happens. So as the server is serving the volleyball, you have focused in on her and can catch her mid-jump, as she serves the ball. Or you could focus on the area between the setter and the front of the net, so that when they dive for a dig, you can catch the moment of their arms sliding across the floor, right under the ball, saving it. Pick where you want to focus your lens and stick with it, shooting as many pictures as you can when the action occurs.
  
  

Multiple Cameras

• Sometimes setting up multiple cameras is the best way to set up the action at these sporting events, so that you can catch the action from multiple angles, so you aren't just focusing on one spot on the floor and hoping you can accurately predict the action. However, this obviously requires multiple cameras and sometimes multiple operators, so this might not be something you can easily do with the equipment at your disposal.
