I went back to the field today.
It was cloudy, cloudy, rainy, cloudy, aaall day long. However, as soon as I left work there was a brief burst of sunshine. I ran to the field, and took a few more photos before the sun went away for the night.
I was so pleased, the sun was exactly where I hoped it would be, and just bright enough to make the flowers shine, with just enough cloud to make the sky interesting. The photo gods were smiling on me this evening.
