Maybe I am missed one when I went searching, but why aren't there any magazines dedicated to sports photography? It seems like there are a million photography magazines out there and there are many dedicated to individual disciplines, especially nature and outdoors. There is even one for taking underwater photos.
It seems like sports photography is the red-headed step child of the photography world. There is only one book that I have found on the subject and one dedicated website (that requires membership), not including a few internet forums. Considering how popular sports our in our culture, you would think that there would be more emphasis on the subject. I'm not trying to disparage any other fields of photography, but I would just like to see more.
