I do a lot of night landscape photography in the mountains. I am looking to get a glowing effect from small pools. I was thinking of getting some underwater lights and placing them in the pools. Any advice on what types of lights i should get (ie: strobe, continuous....). I just want a soft glow from the water. sort of how a swimming pool would light up at night when you turn the pool light on. Any advice on anything involving this subject is greatly appreciated. thanks.
