When does a circle have Three (or Any) Points?

I bought some mini mums in the grocery, the other day, mostly because I was seeing picture possibilities in them. Among the most prominent, to my perceptions at the time, was the triangle shape. Here’s one preliminary play on that theme element.

It was fun finding the triangles in a bouquet of circular blossoms. For added value, I also made a series of 6 shots from the same point of view, but focused throughout the depth of the flower, combined by focus stacking in Photoshop CS5. Lighting was electronic flash filtered through a white translucent umbrella. Some Lightroom enhancements of the final stack returned the warmth of the blossom centers to what I could see, and enhanced the sense of depth by last stage tonal tweaking.
