Thanks for your comments. Shadowman: these birds were running wild around an old Elizabethan House (Moseley Old Hall) where the young King Charles II hid after his defeat at the Battle of Worcester in 1651. Now a National Trust Property. I do have some of shots of the entire plumage which I also like but particularly wanted to capture the beauty of the feathers. I don't think the full view is as good.
A little boost to the contrast would help - thanks for that tip Wendy. I find it difficult to judge because my laptop screen just has to be angled a bit and the contrast appears to increase. How do you know when it is right, can you use a graph in GIMP or some other tool?
