Getting these photo's turned out to be quite a challenge! The two day show was held at the equestrian center, so I thought a great place to hone my skills. Saturday was a disaster, shutter speeds wrong, white balance wrong and focus messed up. 

I returned on Sunday determined to get things right. White Balance - The lights are a yellow/orange halagon and as you pan you also pick up ouside light, as the end of the arena is open. I tried custom first, no good because of the outside light, so wound up using tungsten. F-Stop is constently changing as you go from well light to shadow, therefore you lose your focus because of a slower shutter speed and I had also forgotten to set my auto tracking focus.

So, the above pictures were taken with a 400mm zoom, WB tungsten, ISO 800,  F-stop 1/100. and a little tweekining in photo shop with the brightness and contrast
