I've tried taking pictures of water where I slow the shutter speed to get a softer look of the water. However, I can't do this technique during the day because when the shutter speed is open too long, too much light gets in. Is there a way around this? I'm guessing now, but thought that I would ask anyway.

Could try a higher F/stop or neutral density filters.

I assume you are on the lowest ISO setting?
If you are then as Jaymz says, you will need an ND filter to effectively 'block out' some light

Thanks! I think that the ISO was low, but I didn't think about the fstop.

Put the camera in Tv mode with a slow shutter speed (1/15th or 1/2 sec for instance) and see what aperture it selects, as long as it is not 'flashing' 22 or 16 (depends on the smallest aperture your lens goes down to) you will be OK to blur the water and expose correctly.

Use a CP filter, too, if you need to cut down the light some more. And, as an added bonus, the CP filter can eliminate a lot of the glare on the water's surface so that you can see whatever is in the water better.

What if you stepped down on the exposure?

Errr, I think that's what the OP is trying to do. But he's wants to use a very slow shutter speed and he can't set the ISO any lower and he can't make the aperture any smaller. And hence the dilemma and the reason for this thread. :)

Av mode, roll the selector until the smallest aperature (largest number) that your lens supports is selected. Make sure you are on the lowest ISO (generally 100). Half-press the shutter and see what shutter speed the camera selects. 1/2 second will give decent blur to the water - even slower is better.

A Circular Polarizer will help (generally will slow the shutter down a stop or two), as will neutral density filters.

Most of this has already been mentioned - just thought I'd summarize. :D

Oh, yeah. Don't forget your tripod.

Edited to add: If you're steady, a pair of sunglasses held in front of the lens sometimes makes a good substitute for neutral density filters.

Too small an aperture may create some distortion, too. The best bet for what you're trying to accomplish is going to be with a filter -- either polarizer or neutral density. Using either will allow you to get the shutter speed you want, and the DOF you want, without having to compromise one for the other.
