lcd image exposure - stupid question? Can't Post
This may seem a stupid qustion but how can you be sure that the exposure on the lcd of the VX2100 matches what the ccd in the camera is capturing. We
have had a few instances when the final video is about 2 stops darker than what we saw on the lcd

I hooked mine up to my editing monitor and adjusted the LCD until it matched the monitor.

This may seem like a stupid question also...

But how do you hook up your camera into the monitor to compare?

Do you just plug your camra into the monitor and adjust accordingly.

Example: Camera>SD Studio Monitor via RCA or SVideo cable. Turn on camera to record mode, then view both in my monitor and adjust LCD display accordingly.

I hooked an S-Video cable from cam to monitor. May not be the appropriate way, and I'm sure there is a more technical way, but it has worked for me. Brightness of the LCD matches what I see in the final product. Sometimes it's better just to make things simple.

Perry, thanks for the advice.
I hooked up my cameras to my production monitor via firewire, and was belt to adjust accordingly.
I was actually much closer on exposure and color as I thought I was, but still did some additional tweaking.

I don't believe that I went that long without thinking about making sure my on camera LDC matched.

Duh! Crazy

So, when you step outside in the sunlight it basically wipes your calibration out, yes?

I always use zebra stripes - at 100% zebra the blown-out sections are striped...at 75% the faces should show up as stripes. That way you know what your camera is seeing as far as brightness.

I always use Zebras either at 75 or 100%. Calibrating my camera LCD just gives me a closer representation of what it will look like on my production monitor. For real sunny days, I have a screen hood to give me a decent looking lcd image.

But yes, if I didn't have that then my sceen would be useless. But it's funny how we forget that we acutally do have a viewfinder on our cameras. Crazy
