I'm using magic lantern with my Canon T2i and filming an interview. For this interview I have a three point lighting setup with an additional light with a green gel adding a pleasant splash of color to a black felt backdrop. My settings are as follows: 85mm prime lens at f-2.8, 60 shutter speed, 1250 iso, 3700K white balance. Looking at my camera, the picture looks beautiful. Perfect brightness and the green splash of light in the background is subtle but very effective. Then when I import the footage to my computer, everything looks dark and the green in the background goes from subtle to barely noticeable at all. I have to brighten the video in post which causes it to take longer to export. Also, on a possibly related note, I've noticed sometimes that when I change my iso/f-stop settings, the image on my LCD remains the same no matter how extremely I change my settings (iso settings that should be way overexposed look no different on the LCD screen) and I will sometimes have to turn the camera on and off again once or twice in order to get an accurate reading. Does anyone else have this issue? Why is this happening?
