Is there anything you have in mind? I have experimented with picture control endlessly. I've downloaded the D2x modes and the portrait modes and tinkered with the settings. But I don't think that is the issue.
What I had not really done until earlier this morning is experiment with WB.
It is so flippin' easy I feel a bit daft for not having tried before - though with the D200 Automatic WB was so close to my tastes I had not worried about WB much.
With live view it is easy to experiment - especially that is now that I know that the front control wheel can be used to make fine adjustments. I am generally far happier with an adjusment of a3.
It is like having a new camera! Thanks to everyone who has pointed me in the right direction... and Dave - I really wish you had been patronising, but I fear you were actually talking over my head.
Life and light wait for no man! Now to take some photographs.............
