Green Screen Lighting

For this task Brad Raiser, Frankie Burrows, and myself had to install and light the green screen correctly. We came up with a lighting plan to successfully get a well lit green screen. First we had to locate and set up the green screen, all while taking safety precautions. Once we had the green Screen up we looked at our lighting plan and got to . We decided on the portable lighting kit which were two 300 watt lamps, and one 650 watt lamp. The two 300 watt lamps were positioned on either side of the subject (me) and main purpose were to light the green screen. The 650 watt lamp was aimed to light the subject and ended up being exceedingly bright so we made this diffused to soften it. We encountered a problem from the 650 watt lamp, it casted unwanted shadows on the subject. We corrected this by adding a 500 watt flood light on the lighting bar to counter the shadows. We then thought this lighting was sufficient to shoot and capture footage for but we still had to check. We set up the JVC camera on the tripod to try and hook up to my Macbook. We wanted to use video scopes in Final cut Pro to see if we had lit the green screen properly and accurate light reading. Since my Macbook is an older model from 2007 it takes a 6 pin firewire, so we ran into a problem to locate the 6 pin to 6 pin firewire. Since we couldn't obtain this cable we had to make dew and find another way to measure this ambient light. We decided to use the light meter instead, we had an average overall reading of 3.4, which we were happy with. We then filmed myself on the green screen not really doing anything in particular. I just moved a bit to show that the green screen has been properly keyed. I'll admit that our lighting wasn't perfect. If I could make one suggestion it would be to add a light (parcan) behind the subject to light the back to make it so the light sources come from every angle. This all and all was a good learning experience for my group and I.
