Hi Mary! Thank you so much for your challenge. I want to challenge you to try to take a photo that captures what Henri Cartier-Bresson meant by "The Decisive Moment". It does not have to be a street photo, but anything where timing matters. Here is an article that can help you with this task - also written primarily about street photography, it can be applied otherwise as well. Let me know if that would not work and I can come up with something else. http://erickimphotography.com/blog/2010/07/01/“how-to-masterthe-decisive-moment”/
