I am a very amature photographer and I have a Cannon EOS 550D and when I try to play with the AV (appeture setting) alot of my photos come out looking blue.

I have attached a pic to show you what I mean.

I have played around with all the settings and read the manual and have started to read the photography course on this website but I cannot fix my problem.

Thank you so much
