Seamus Donahoe Posted December 16, 2009 Share Posted December 16, 2009 Hello, I've got a bit of a puzzle that I can't quite figure out. I'm currently temping as a manager at Emerson College's student equipment rental facility, and a student has asked to rent an 85 filter for an HVX to be used during a green screen demo. Unfortunately we didn't have one in 82mm, so it was kind of moot anyway, but I'm still curious what it would be for. He said a professor had suggested it, and couldn't give an explanation. My initial thoughts on this were: well, why would you need a filter when you can white balance to whatever color setting you want (cheeky, I know), but then I thought maybe (under 5600K) greenscreen reflects it's tones more vibrantly thus allowing for the possibility of a more accurate chroma key. This in turn could run the risk of there being too much bounce onto the subjects (space limiting), so the 85 could be called in to cut down on this spill, while maintaining skin tones (if balanced for 3200K). But then, that means that everything coming in the lens would be balanced, which would equal out the intended effect on the greenscreen. Either way, I'm stumped. Does anyone have any thoughts on this? Thanks, Seamus Quote Link to comment Share on other sites More sharing options...
