FujiFilms WBS solution.

Hot off the press, just got a reply from Fuji UK.

Dear Paul Till,

Thank you for contacting FUJIFILM UK and we apologise for the delay in replying to you.

Thank you for the example image of which we have inspected. Please note this is not a fault with the camera, this is a digital artifact known as blooming and this can occur with all digital cameras, regardless of make or model.

You can use a smaller f-stop number or ND (Neutral Density) filter to reduce the amount of light, increase the dynamic range to reduce blooming and I would also suggest using the histogram to expose the image, when capturing similar pictures.
we apologise for any inconvenience caused.

Well if that's there answer I guess mine is going on e-bay this week.

Paul.
