One more thing, when I started, 2 1/2 years ago, I began with a 30D and a 70-200 f/2.8 IS lens. The images were never close to the results obtained by Dennis, Kevin, or any of the really good shooters. Upgrades to the 85mm f/1.8 followed in order to lower ISO and gain SS. Then a 1D Mark III was purchased to get better IQ, more fps, and improved higher ISO capability. Got an expo disk and then began shooting white balance on grey or white cards. Shot it RAW to try and get better colors. Also added noise reduction and improved software. It all helped a bit and doing that taught me a lot but it still didn't result in the quality of the top shooters. Then one day I shot an away game at a new gym that had double the ambient light levels of my home gym. It had both florescent and bulb lighting--lots of it. Presto! One year after I had started, I finally got some pics that convinced me that yes, even I could take quality images that someone else would like and would hold up to critique at POTN. Until then, it seemed my images were never going to be even mediocre. It was all about quality light. Shooting ambient is wonderful if the light is there. If not, it must be obtained with speedlights or strobes. A proper photography education must include the techniques for using both as the situation demands. It's great to shoot in a venue with light of high quality and quantity. Leave the lights at home and fire away at high fps. What a joy to shoot at an arena where they have bright lights for TV. My favorite volleyball images were shot ambient at such an arena. Unfortunately, that's not the way it is at the local middle and high schools. The cruel truth is that the starting photog needs the most help in poorly lit MS and HS gyms and they are least likely to have the tools (lens, camera body, lights) to do it. The wonderful new camera bodies with incredible high ISO performance will help but will never be the total answer to the need for quality light.

PS. With the strobes and a white ceiling, these images were shot jpeg and AWB. Easy.
