Later this month, I have the opportunity to photograph race horses in their practice runs at Del Mar Race Track in Northern San Diego County. This is the track about which Bing Crosby (anyone remember him?) crooned, "Where the Turf Meets the Surf in Old Del Mar"
Anyhow, I plan to use my 7D Mark 2 with my 100-400mm f/4.5-5.6L IS II lens. I have researched old postings about shutter speeds and think that I may want to shoot at varied speeds. Horses are very different from panning cars and airplanes because they bob up and down and their legs are working at all different angles and speeds.
I think that I am going to use aperture priority and set up the ISO and aperture so that my shutter speed is about 1/125 second and then use auto exposure bracketing of + and - one stop which will then give me shutter speeds of 1/60. 1/125 and 1/250 second for each three shot burst. Using the AEB seems to be the best way to get a variety of shutter speeds, to blur portions of the frame and subject. I will see how the images come out and then increase or decrease my original shutter speed.
Nice thing about this opportunity to shoot the practice is that there will be many horses running and I won't have to wait an extended time between races. There will also not be a crowd that I will have to buck to get near the fences. The bad thing about this photo opportunity is that there won't be a gaggle of horses racing each other and I don't suppose that the training riders will be wearing "silks"
Well, you can't have everything
