ex1 auto trace white balance issues
on May 28, 2009 at 6:49:05 pm

When I need to use Auto trace white balance, I find the camera slow to react to changes in lighting.
For example, shooting in ATW mode and going from outside sun to inside tungsten. The ATW speed is set at 3 however I'm not noticing a change in speed for the ATW. Does anyone have any experience with this?

Is this just how the camera works or am I doing something wrong.

Thanks for any help.

I have the same problem. The camera can take as long as 30 seconds to react to lighting changes.

You can set the speed of WB.

See manual.

Below is a screen shot from p 117 of EX3 manual.

Thanks for your help. The problem is no matter what ATW set number is set you, it's always takes 10 seconds to change. Anybody have any ideas before I have to deal Sony>

Thanks

Tom

I would suggest contacting Sony, and please report back what you find. I did a wedding yesterday, and had to rely on ATW in a couple of instances. I have the speed settings on the highest number, and the camera just took it's good time before reacting to changes in light temperature. Sometimes, it's a minute or more before anything happens. Useless!

Even when the ATW is set to the fastest speed(9), it still takes a about 4 to 5 seconds to adjust. But what I have also noticed is that halfway through a 5 minute shot, with no lighting change, it re-adjusts to a better white balance, completely ruining a take.

I shoot a lot of video that does not afford me the time to manually adjust white balance. I've owned many cameras over the years and find this camera's ATW function completely unreliable.

I guess it's Sony warranty time.
