well i think i may be the only other skateboard photographer on this forum, so if you ever need any help, let me know!
about this photo i will go ahead and tell you one rule about skatography.. always get the frontside of the skaters body. you never want to get a butt shot like you did here. unless it is un avoidable like a bs 180 trick down something, but even in that case you can find another angle... another trick is to use the rule of thirds, dont always center your subject. and try to get a better composition. this looks really point and shoot. if you want check out
SkatePerception - Skateboarding's Premiere Online Technical Community. Now Offering Photo & Video Uploading for more advice. but i will tell you that the people on that site a harsh, inconsiderate and cruel. i dont really go on there anymore because of everyone being hateful. they will down talk your stuff alot and will only give compliments on people that post regularly and have been on the site for 5 years. its dumb, however you can learn stuff from that site that you cant on here..
