I went to the RAF Museum at Hendon today to put into practice some of the thoughts I’ve had as a result of this thread. It’s clear that the lighting in the Main Halls is not ‘daylight’ but tungsten. Once I set the white balance to tungsten there wasn’t a problem. See

I still have issues with the BoB hall where the lighting is awful and very blue. Also the ‘Milestones’ hall has mixed lighting, natural and florescent. I set the camera to ‘cloudy natural’ but clearly this was a mistake, it should have been florescent, see

Still, in spite of the reservations these are very much better than those I had before. You can see the entire set of 92 frames at http://www.flickr.com/photos/68685377@N04/sets/72157628986158899/ if you wish. My thanks to all those who contributed.
