Thanks Stan for organizing an interesting night at the greyhounds. Thanks also to Karen Giblin who shared her expertise. It was certainly a challenge photographing fast action in low light, and it happens all so quickly. I didnt get much, but here is one shot I took ISO 2500, shutter speed 1200. It was very noisy, but after noise reduction in Photoshop its not too bad. Hopefully others may wish to share their photos
