Every so often I am finding my photos and video clips going a strange strong blue tint. Here is an attached example.

Vote Auto White Balance?

Well it was on the Auto Pict setting - so I presumme that was on. Would you set the white balance manually for each situation?

I'd choose the most appropriate. And if nothing suitable shoot RAW and develop to order later. I've never done a manual white balance set. Might have a go to see how.

I personally only bother with manual settings like Tungsten if the AWB is struggling.

The chance of the AWB not being accurate is a lot lower than the chance of me forgetting to change the setting!

I see what you mean Gareth. I found the Exif data. I did not manually select Tungsten so I am puzzled how it was selected. As far as I know the K-x was on AWB. I have a video clip where it starts out with a blue tint which disappears half way through. It's as if the AWB is thinking one minute this is tungsten lighting, and deciding it isn't.

It was set to spot metering. Could that be the cause?

Spot metering will just affect the exposure.
White balance will affect the colour tint.

I guess you shot in the evening. You could try "shade" next time.

Hi Nigel,

I see you wrote on Flikr that you are relatively new to all this (welcome!).

While this won't solve any issues specific to your individual K-x, it may help you understand some of the underlying principles better. It's a great resource IMO - link

Good suggestion. I'll give it a go - although two of my video clips were taken in bright daylight and they had the blue tint.

Thanks i-berg. This looks to be a really useful resource.
