I like this idea a lot. Seems like there needs to be several different challenges, some are pet related and some not. maybe one this month and one the next?
James, I still remember very fondly a challenge I was given in the one photo class I took at 19. It is tough, but I had so much fun doing it and took one of my favorite pics this way.
Challenge - 10 photos from one spot, of as many different subjects as you can find. You can turn, kneel, bend, or anything like that, but stay in that spot.
Or - Something the size of a quarter or less (for a one shot challenge)
