White Test Problems

[ryanbasham]

Hey everybody,

I'm having trouble doing a white test on my DVX 100a. The PRST setting desplays Awb P3.2k. A displays awB Ach. B displays awB Bch NG.

I have consulted the manual, searched online, so on and so forth. I keep getting these same messages? What am I doing wrong?

Also, I just noticed a couple of bubbles below my lens when I was looking into it while changing filters. It's set away from the lens. Should I be conerned?

Thanks a million,

Ryan

Hey Ryan,

SIMPLE answer is it was too bright whe you tried to white balance.

With your white balance switch you have 3 options from top to bottom(B,A,PRST). A and B can be white balanced by you in any lighting situation to tell the DVX computer what true white is. PRST has two settings that cannot be changed. To switch the PRST between the two presets find the AWB button below your zoom ring in front of your gain controls. Press the AWB button to change between the two presets which are 3.2k and 5.6k. 3.2k is usually used indoors because it is a cooler white balance. 5.6k is usually used outdoors because it is a warmer white balance. Warmer and cooler is refering to color temperature which is called Kelvin. 3.2k=3200 degrees Kelvin.

To set your manual white balance switch to A or B and aim the camera at a white wall or other white object and make sure the lcd is filled with only white. Now just hit the AWB button and you will see a message on the lcd saying: AWB Ach/Bch ACTIVE and then you will see another message: AWB Ach/Bch OK. Now your set.

Errors: 1.) If you see AWB Ach/Bch ACTIVE then see: AWB Ach/Bch NG LEVEL OVER: This message means it's too bright to get an acurate white balance. To fix this just flip your ND switch and darken the white object you are white balancing.

2.) If you see AWB Ach/Bch ACTIVE then see: AWB Ach/Bch NG LOW LIGHT: This message means it's too dark to get an acurate white balance. To fix this just use more light and make sure your iris is open with the ND switch off.

On a sunny day the sky can be 11-25k or 11,000-25,000 kelvin. Most of the time the 5.6k preset works just fine. The lower the Kelvin # the more blue and the higher the Kelvin # the more red. You can also trick the DVX by white balacing on a blue surface to make the image more red and likewise you can white balance on a red surface to make the image more blue.

Good Luck
