I usually take photos of planes touching down with my F717. However, my photos are not really sharp. I believe that maybe I'm using the wrong settings. First of all, for planes touching down and moving fast, is the best setting Aperature F8 and shutter speed 1/500? If so, should I then use the Manual Mode of the F717 so I can manually adjust both the shutter speed and the aperature?
Furthermore, what exactly causes motion blurr and how do I prevent it? I have been told by an expert that my photos are not that sharp supposedly due to motion blurr. However, I'm quiet certain that I shake my camera when taking pictures.
