Use the flash. If you're close to the lights, you shots should be OK. If you aren't, the pictures will be iffy at best, even with the flash, unless you're right on top of your subject.





Here's a couple of other tips:





Get the fastest film you can for underwater work. I would go with a 400 minimum, but 800 is better. These are more sensitive to low light conditions. And even a few feet of clear water will absorb quite a bit of light.





Stay out of the pool for awhile before you're going to shoot, and run the filters and vacuum the bottom beforehand. Then let the pool sit quietly for awhile. This lets floaties float away, and sinkies settle to the bottom. Either will cause spots to appear in your pictures if they are suspended in the water.





When you do get into the pool, try to slip in quietly, rather than jumping in and splashing around. Then keep your motions to a minimum. You want to keep from stirring up the floaties and sinkies again. You also want to minimize the number of bubbles in the pool. These will reflect the flash and cause white spots in the pictures. DON';T jump into the pool and expect to get great pictures, unless you want to see mostly clouds of bubbles and a blurry something that might/might not be a person.Do I need to use flash when taking underwater night pictures in pool?
If you want anything close to natural white balance you are going to need a flash.





Also, no matter how bright it is to your eyes it is still going to be dim for your camera. Flash would help there as well.





Have fun....
My sister has a waterproof camera, and the pictures look fine in a clear pool in the daytime. I'm pretty sure you'll be fine with or without a flash on with the pool lights on, but that's just me
