His name is Walter Baxter. I have blogged about him before and Shirley and I met him back in 2013. Walter and I communicate by e-mail from time to time.
The image is of course of a farrier shoeing a horse. In that time-honoured process, there will often be steamy, smoky moments like this one. However, after searching through Google images, I doubt that any other photographer has ever captured the traditional equine scene as well as Walter has done.
