Hi. Thanks everyone for trying this. Certainly made a big difference to the image!

I have had a go but honestly I didn't really get anything that I liked better.

I think the above changes do make an improvement, especially making the feathers more white (How do you do this? - I just end up blowing the detail) then it becomes very clear how yellow the original is.

When I first saw the modifications in the post directly above I thought it looked a bit artificial, but now I see it on a different screen and it looks very good. I guess one lesson is that how the monitor is configured makes a big difference.

I'll keep trying myself and I'll post my updated eagle pic when I have an improvement...
