So I like shooting small streams and waterfalls in the forests around my house. I shoot with a Canon S3IS, one of the better P&Ss from what i've been told. Im what one would be considered a noob as well. Regardless, People on here tell me to get the water to look "silkier" or appear to be "slower" that I should try a longer exposure. Does this mean increasing the shutter speed? I try to shoot on the lowest ISO setting to get higher quality, but with increasing the shutter speed to more than a 1/4 sec, all the light that goes into the lens makes the picture look so darn bright. So my question is whats the best way to shoot these longer exposures if the increased shutter speed allows excessive light into the lens?
