Topic: Quick Cam Pro 9000 is being light sensitive?

Recently my QCP has been extremely sensitive to lights. For example I am try to film a scene outside a white house, my cam is fusing all the white bricks together to make a ugly white blaze. I have rearranged my lamps many times with no effect (except for when I turn one off ).

I have also set the settings in the QCP camera program to where the set is back to normal. but it suffers from extreme light ficker. I have no idea how to fix this. And it wasn't like this when I first got it. Replys are gladly appreciated mini/sad

Would you be able to show a couple of screenshots that show what you mean?

One thing you might want to consider is using indirect lighting. With this technique, you aim your lamp AWAY from the set, onto a white sheet of paper. You then place the sheet of paper in such an angle that the scattered, reflected light comes back onto the set. This gives you much softer lighting to work with. It's similar to these guys using white surfaces to get perfect lighting:

Sounds like you have some of your settings left on auto.

Re: Quick Cam Pro 9000 is being light sensitive?

Nope, everything is manuel. Indirect lighting is a good idea, do you know a specific setup for 2 desk lamps?

Why are you saying everything in bold?

Seems like your exposure and gain settings are a bit off.

Hmm, using two desk lamp you might want to consider one lamp being the "main lamp" that creates the deep shadows, and have the second one as an indirect light source to create some filler light (so that dark spots aren't too dark). There are two (rough) ways to make an indirect light source.

The first is where you point your lamp away from the set, towards a white sheet of paper. The sheet of paper is placed in such a way that the light will reflect back towards the set. Tthink of the sheet of paper as a mirror, and you need to try getting that light through the mirror onto your set.

The second way is to actually tape the sheet of paper onto the lamp, and make indirect lighting by using the light going through the paper directly onto the set. Please make sure you use a low wattage lamp when you do this (25W), because if you are going to use one with a high wattage, your lamp will give off more heat, and your paper might catch fire. No, seriously, it happens.

On top of that, try experimenting with some different exposure settings (like 1/100 instead of 1/50 or 1/30). This will possibly help as well. However, if you have too much brightness on your set, and you compensate it with too fast exposure settings (like 1/250 or higher), you will experience extreme light flicker. This is because your lamps flicker at a very fast rate so that they don't overheat. This is way too fast for our eyes to notice, but a camera with fast exposure settings can see it perfectly fine. I think this is what was your initial problem: brightness too high, exposure settings too fast to compensate.
