Female Boxers fight it out at the Fast Katz Ladies Boxing Show held at the Salvation Army Gym in San Antonio. The lighting was very bad for the camera, I took most of the photos at ISO 51,200, 1/350 sec @ f/2.8 (Nikon D3s with Nikon 300mm f/2.8). Although the D3s will go to ISO 102,400 I found that ISO to be worthless in this situation. It's important to know the limitations of your equipment. Because once you understand what your camera can do, it will make you a better photographer. The image was processed in Adobe Lightroom and converted to B/W using Topaz BW Effects.
