Here are a few shots I have taken. I do, or used to do, a lot on the waterskiing/wakeboarding/kneeboard/boats photography but only cover a few events a year now for fun. I'm self taught and I know there are quite a few people on here who are much more skilled than me who can offer advice on setup etc. The pictures were taken on my Canon 1D a few years ago. I then stumbled over them a while back and thought I would try out the editing on the iPad/iPhone (can't remember which now) with the various apps so apologies for the boarders etc. if you don't like that sort of thing but it was a sort of experiment to see what the app could do. I sit in the water while the skier goes around or passes me at between 36-70MPH depending where he is. The last shot I was sitting about 3 feet off the buoy with the skier passing pretty much over the top of me. The wide lens (I think it's about a 12 or 13 - 28 - not got it with me to look) allows me to get really close up, not something I would attempt unless I know the skier - a lot of trust required, but on that pass I didn't manage to get him in full frame but quite liked the buoy with the spray around it that I got after he passed. I'll add some more if you like with some of the other sports and things I have taken over the years as and when I can.
