i have a project which i need some advice on. I am part of my school yearbook and came up with a cover idea that requires photography. the idea is to have a line of people about 30 feet long that are holding hands and jumping in the air. I have 5 d80's and radio remotes to fire them simultaneously. i am planning on lowering the tripods so the camera are near the floor and looking up toward the people a bit. I am planning on doing this in the school gym which would allow me to roll out a white backdrop along the wall. i want white so i can easily cut out the people, or blend it into the white background on the cover. my problem is with the lighting. the lighting in the gym is not very bright at all and it is a weird color. i took pictures of a volleyball game in there recently and half the pictures were orange and the other half were blue. the color wont be a huge issue because i can preset the white balance, or fix it in photoshop if worse comes to worse. I am going to use 50mm 1.8 lenses because they are fast. unfortunately they are not as fast as i need. when i was doing the volleyball shots with this lens, i couldn't get above 1/250, and this is not nearly fast enough to freeze motion, especially with people jumping in the air. I realized that i need some extra lighting, but i have virtually no experience in that area. i own one sb600 which i hardly ever use. i dont have the money to buy a bunch of flashes, so i was looking into continuous lighting. it seems like it is alot more accessible money wise. If any of you have any suggestions concerning lighting (or anything for that matter), or have any good resources, please let me know. I have ran across and heard about the strobist site, but i have never needed to use it. is this a good place to start even if i am not using strobes? oh, and this is under a bit of a time constraint because the cover needs to be submitted by the 30th. i am hoping to place my lighting order this weekend, and expedite the shipping. thank you all very much, and sorry that this got so long.
