OK, this might be obvious, but after reading the manual again it's still not clear what will actually work.
Last night when I was attempting to tape video in moderately dim conditions ( I could see fine, though the area felt dim ) the 852 showed some parts of the action as shadows - I just got a grey shape rather than a normal image. This depended on the subject's position - a foot or two more away from the overhead light and they become a grey blob. I was suprised, since with some tests around the house it seemed to work in dimmer conditions than last night. I had it set to auto, with the backlight function on.
1. Would gain up (if the cam has it) fix this problem, or was it just out of the ccd's range, period?
2. I don't see an option to set the shutter below 1/60th. 1/30 would blur too much, but I could try 1/50.
3. What does the 'Iris' function actually do? It sounds like the gain adjustment by another name.
4. If Iris is actually Gain & I use it, does that also cancel all other exposure adjustments? I still need the cam to auto-adjust for different degrees of dimness, and still need backlight mode. Even with backlight mode on, the subjects are too dim since the cam is trying to compensate for the incandescent light bulbs. I don't care about anything other than the subjects - if those bulbs get ugly so be it.
5. I could get away with a small, soft cam mounted light if there's no other way. More gear is not better, it could mean losing a shot while fiddling with the gear. Any thoughts?
thanks,
Larry
