First skate shoot

This is my first skate shoot. It was a practice shoot to help me understand which techniques I should use in my next shoot. I first wanted to use long exposure but I soon realised that the skaters I was photographing were moving too fast for the camera to capture any detail. In some of the images you could see a vague outline but they weren't detailed enough for the image to work (the best two long exposures are bellow).
So after this I decided to use the flash. This made the images clear and sharp but gave a starkness to the images. So in future I will use a cold light to add contrast and take away the starkness of the images. I want to use a cold light as a more yellow light would make the images an orange tint and there is already enough yellow light from the street lights.
Although I do like some of the snap shots using the camera flash as I feel they look raw and less staged. But for more of a professional style shot its will look better with a light.
