Moon and Pool

Nice idea ... And if you were after over-exposure (as in an abstract image), then you definitely succeeded.

My suggestion would be to shoot/meter on/for the full moon, then reframe and shoot.

Try F11 and a shutter speed of 1/film speed (info found on this very site under the star streaks guide at http://www.photo.net/learn/astro/star-streak ), which would be like 1/400th with ISO 400 or 1/200 for ISO 200 ... etc.

Next full moon give it a shot ... I think this image could be really great with the proper exposure.
