How to make good pictures at swimming pool?

I'm at my brother's swim meet and I want to do cool photos. My camera: Nikon D70's.

Place it on sports menu. It will mak the pictur clear for swimming!

Since this shows the question as posted 3 hours ago, I suppose the swim meet is over? Next time ask such questions well in advance of when you need to know such things.

Since there's fast movement at a swim meet, you need a fast shutter speed to avoid blur. Use shutter priority on your camera and set a speed of 1/250. If outdoors where there can be glare on the water, use a polarizer filter on your lens to help wipe out the glare. You have to adjust the filter to remove the glare. Set ISO to 400. If the camera can't set an aperture for proper exposure, then begin to raise the ISO only as much as needed to get proper exposure. You do know how to read your camera light meter don't you?
