[QUOTE=Stormrider;4427172]If you're going to shoot while going by, you should cut your shutter speed. It can be compared to taking photos at the 500, except worse. There, you're setting still and the surrounding landscape is too, so you'll end up with a beautiful background and a highly blurred subject. But from the car, the landscape and the subject is moving because you're sitting still but in a moving focal point. Put the camera in manual adjustment mode and cut shutter speed and it will leave it open less time. However the image data and color saturation will probably be less. The higher the mp of your cam, the less this will be affected as the assembly that processes it is higher quality. But to make up for the higher mp (which means more data to process) it's probably best to reduce the image size in the settings a bit, which will make the photo unfortunately less clear if it is blown up. Your best bet on shooting walkers is to not wait until you are right beside them. Shoot from a distance down the street with the cam pre-zoomed. Shoot a burst shot and chances are one will be better than the others. I'd also not use auto focus since you're moving. Play a bit with some focus settings and distances until you find one that floats your boat. I process around 5-600 pictures a day between my two jobs and one of them is for a paranormal investigation team, so I've had to learn the hard way about camera limitations. Oh...one more thing. Cell phone cameras are the WORST with moving subjects. Just a limitation of the tech to this point.[/QUOTE]I actually do shoot from a bit of a distance with the camera pre-zoomed. I cannot imagine trying manual focus while driving. With the camera already zoomed, the field of view is pretty narrow and just getting the gal in the viewfinder is difficult. I have tried manual settings and they haven't been any better. I have the best luck if I happen to be at a red light or stopped behind a turning car with a gal walking or standing not too far away. I'm happy enough with what I get.
