Great fun at the skateboard park and I was seriously impressed with the talent of the kids. I must also say I was more than slightly concerned for their wellbeing should they fall, which undoubtedly happens periodically.
I'm not sure the 50mm lens was the best choice ... something wider and lower down may have worked better, but I was trying to get shots for my 505050 project!
The lens was pretty well wide open, ISO was set quite high and ISO 800, shutter speeds were then 1/4000 sec and faster. I shot JPEGs as this allowed a faster write to the memory card. Great fun. Take a squiz at the shots and let me know what you think. Better still give me some hints on how to do things better!
