yep yep , panning the camera will make the rider more in focus because the autofocus locks onto the rider instead of the rock. And since the camera is moving, it recognizes the blur and often uses the widest Aperture (lowest number) and the fasted shutter speed.
I have a question for you smart PhotoPeople. EXACTLY (no guesses please) what does the camera change when you change the ISO settings. I know that with film it is relative to the number of particles and how sensitive they are to light (faster film = larger particles that are more light sensitive). With film, as you increase the film speed the pictures become more grainy because there is less definition in the negative. But since a Digital Camera doesn't use film, how is it possible to change the ISO? Meaning that even though you set it to be more light sensitive, there is still the same amount of grains ("light sensors"/pixels in a digital camera's situation) in the "film". Know what I mean?
And another question. Does anyone have much to say about the digital camera : Sony Cybershot DSC-F707. I know that they changed the model number to F717, but is there any difference? I just bought a F707 through Ebay and might return in under warranty and get the F717 because bright lights send streeks across the LCD Screen. (well, once in a while it does that) It's been a great camera for the past few days, just got it and took some cool picture at the World Round at Duluth, MN, USA. I observed the event on Saturday (it rained and was really muddy) and then on Sunday I spectated (it was great out). My camera is 5mp effective, with the 5x optical Carl Zeiss Vario-Sonnar zoom. ::
So yeah, those are my questions. Thanks, TravisJ
