I was tempted to delete the previous message, as it is clearly off-topic.
On the other hand, it made me think of an interesting subject foor discussion here: what is "good" sports photography? Is art involved in capturing the right moment? What special techniques are there to know?
And especially with regards to martial arts (I have to admit, I very much neglected my Aikido training lately): is it possible to illustrate the spiritual background of the training?
