The ultimate in having a bad hair day! It is not only aircraft that you do not stand behind on take-off! Great tit taking off nearly blowing the head off a Goldfnch about to make a quick exit in the opposite direction. It happens at speed - the 40D shoots at 6 frames a second! This was on the far right side of the next frame! iso 1600 - f2.8 and 1/2000th and it still does not freeze action on a small bird!
