This is a picture of my daughter and a horse she used to ride. What made this shoot incredibly difficult was several factors. One, I had zero assistants and had to set up by myself (5 light setup) and basically had to guess, because any adjustments mid-shoot would spook the horse. Which leads me into the second part that made it difficult, the almost 2000lb animal that would spook at its own shadow. The third part that made this difficult was this was at night, when other horses were in surrounding stalls and weren't thrilled about being disturbed with strobes going off.
I was able to get 5-6 useable photos in 10 minutes and we called it a night.
