Thankyou all for you import, David, I can not see them on the RAW files but they are there when they are exported to Flickr
Neil, you correct in saying "its like a gradiented halo around the top of the aircraft?"
Its annoying as it shows up badly (to me) on my MacBook Pro
Does the problem only show when uploaded to flickr, or is it present in the JPG you have saved on the machine as well?
The problem mab well be created by Flick'rs resizing algorythm?
