Stephen,

Having just been through your gallery I cannot imagine you being much troubled by this. I notice you have only gone below f8 on your closeups. Always a f8 or wider on aircraft shots.

Just wondering if you are honing your reactions on Hoverflys as per Christines ( Sapphires ) pic. http://www.worldphotographyforum.com...ppuser=57&sl=s
