Hey all - Im killing myself here. I have been trying to take photos of GREYHOUND RACING. I just cant seem to get the photos clear or sharp. Plenty seems out of focus. Im thinking maybe shutter speed might wrong or something like that. What would be the best settings for these fast moving animals - they travel around 64 klm (40 mph) per hour when racing. Most of the photos would be taken from side on. I am a total novice at this and have absolutely no idea. Most photos will be taken at night under lights and flash photography is NOT allowed. Thanks in advance.
