So I'm shooting photos for the local NPR affliate. Particularly a new pilot show they have called 'The Loop' that is more like an open forum with a general topic & audience participation. So, it's a regular 'forum', with people coming in to sit down and listen/respond to the host. It's recorded for the radio, then edited and played the next day. I'm using my 50mm f/1.8 to take the shots and it performs *ok* though I wonder if I should spring for the 1.4 version. Anyway, my problem is lighting. During a lot of the segments the lights are dimmed and the area is light up with 2 large cans with red gels on them. This, of course, really screws up my camera and I end up with an all red shot - unless I can manage to meter off of another light. So, that's problem A. Problem B is when the house lights *are* up, there are a lot of harsh shadows and exposure problems. I've both blown out highlights AND underexposed in a single shot. I can adjust it to where I end up just slightly blowing out parts, but my camera can't seem to meter properly something like, ohh, a black man in a white shirt/hat/pants with a spot on him and dimmed colored lights in the rear. So, odds are I'll have to 'live with it' but I was hoping maybe someone has done something out there. Also, do you think it would be worth it to get that extra little bit of aperature in going from 1.8 to 1.4? Otherwise, I think I'll invest in a wideangle prime instead.
