Marsh marigolds

I hope I've solved the white balance problem. It's so obvious in this photo of marsh marigolds that, with the help of a Fuji forum, I eventually tracked it down to the white balance shift setting, which I had somehow managed to adjust towards red. I'll check it tomorrow.

This is the only marsh marigold that I've ever seen along this stretch of the river. It's there every year, and seems about fully out now. It's on a little stream that I think arises from a spring about half a mile away, but which only runs over-ground for the last 50 yards or so before it enters the river.
