Horse Power I think it's safe to say I photograph, on a regular basis, all variations of horse power.  The pressure is present in all aspects of sports photography, after all it's not a rehearsal, and even then, patience is a virtue and observation is paramount to capturing the moment,  I'm always looking to create a story, a sensory image for those who couldn't be present.  No matter what the sport, I like my pictures to show movement, like with this image, setting the camera so that you can get the sense of speed from the racing horses.  Focusing on one horse in particular, Lady Cardinal, trained by Naylor Racing, the blurred background and her mane give you that sense.  

Understanding the 'how to' of your camera, in manual setting, and of course understanding the sport you're photographing go hand in hand.  For me personally, as my background is so diverse with the various interests, hobbies and sports that I've participated in and follow, has, not so much made it easier for me, but has definitely aided the taking of photographs in my preferred style.
