It was the "Edinburgh Riding" a few weeks ago (Ok, prolly a month ago), and I took the opportunity to shoot dozens of photos of horses and riders for reference purposes because horses and people are right hard to draw. I wish I knew more about equestrian stuff. More to the point I wish I was better at drawing them. No excuses now eh?
What was frustrating after shooting the horses was that I shoulda done it from more angles - I could have gotten on my belly to replicate the same eye-level shots I was taking. Maybe next year.
