Following a few discussions with a few people I have been playing around with Black and White for a couple of my sports images. I have uploaded two images to my 500px page and I have been getting some nice feedback from people online, via email and offline.
The image above is one of my favorites. It was taken as I was turning around and I had a split second to capture the togetherness of the two girls as they were warming up for the main gymnastics session. The focus is slightly off of their faces and owing to the low light available, the depth of field was very shallow. Despite the slightly soft faces, I really like this image, not least because it really encapsulates the friendliness of the whole club.
You can view a larger resolution example and also a black and white image of an archer in a similar casual moment on my 500px page.
