Hi all, very new to photography, although I consider myself to have an eye for a good picture and to be able to compose a reasonable shot. I have just purchased the new 400D Canon and need some advice about shooting air to air shots. I am a keen aviator and have experimented with taking pictures without choice through a perspex canopy. These shots are mainly of other aircraft in my aerobatic group. I used a polariser on the lense, to capture the blue skies against the aircraft. Can anyone advise me or point me to general setting to use for this type of composure. I tend to find propellers are "frozen" rather than a nice clean arc whilst they are in motion. On another note, I would like to know what settings to use on a sunset composure, (ie) a shot fully into sun when the sun disc is a glowing red rather than bright yellow. And (I promise to shut up rabbling in a mo) I would also like to know how to compose pictures of people fairly close up with a blurred background both at night and in the daylight. Your thoughts please?
