There was a great horse event in South California. I shoot horse events during our season here. It’s a unique photo session, but one of the most challenging I've found in 40+ years of photography.

Is there anyone else out there??

Yes, I know the event. There is one member who is interested in starting such photography, but, he was not much experienced. It was a great event.
Meanwhile, I'll keep my eye open when I browse people's websites.

Please consider posting some of your pictures. That is IMHO, the best way to get the others to beam in!
In 2000 I began shooting riders from the barn where my daughter rides. (This is for fun and memories, not as a pro.)

You'll find equestrian photos in my Phase account, mostly in the Hunter/Jumpers and Ireland galleries.
