White balancing issue on my 200u... at DVinfo.net

Jonathan Rosenberg · August 4th, 2008, 06:00 PM

I was outside filming with my 200u and I put my preset on 5600, which should have been fine, but it was pretty blueish greenish.. So, I white balanced and it gave me a warmer but truer colour but the temperature read at 5200. How is this possible? wouldn't making the temperature a lower number make it bluer..?
AND
when I set my preset to 3200 or 5600 and they're different then when I manually white balance and get the same exact temperature...
Is it possible for an auto white balance to read strange temperatures like this?

also My gy-200 (the same camera I'm having problems with) AWB's nearly 2-400 K different then my gy-100u? althou they look nearly the same in colour either than a few little details..

Has this happened to anybody before?
help.

Hi Jonathan.

I've heard of this issue in a few cameras. Actually... it was at a JVC roadshow event in Hamilton. A representative of JVC Canada was in attendance and he explained that there are two elements to the AWB process. First, white balance is corrected based on the sample from white card, chart or gray card you are using. Secondly the system reads this adjustment and then displays it to you in Kelvin.

Apparently the second part of the process isn't always calibrated properly to the first. You may be in 8000K and the camera WB'd correctly, but it will read as something lower or higher.

If you are still in-warranty I suggest you call your dealer and ask if they can arrange for the calibration of your AWB. If the camera is out-of-warranty you may want to call the service department at JVC Professional Canada or just drop it off. They are located in Scarborough.
