It was a good idea to put these strips of muslin over the pool. They soften the sunlight enough to survive it for more than half an hour.
We started out calling them 'canopies', but over time, we've all taken to calling them 'sails' because that's exactly what they look like in the wind.
Underneath them we tried some underwater photography. We had absolutely no experience and learned that it takes some real coordinating to make this happen. The morning session was more funny than productive, but by the nighttime shoot, we'd figured a few things out and the three of us became a team: One to be the subject, one to shoot and one, wearing weighted shoes (ummm, not recommended attire for the inexperienced swimmer) to keep the photographer from floating to the surface.
One, two, three...GO.
We used film, so couldn't know immediately what we got, but....really, it didn't matter that much at the time.
And still doesn't.
