The interplay of light and shadow -- fascinating! I like that little round drop in the shadow of the big drop above, and the subtle play of light and shadow that allows us to see it. And then there's the pattern of light and shadow cast by the dewdrops below. And the patterns of light and shadow on flowers, and through flowers.
"Instructions for living a life:
Tell about it."
Mary Oliver in "Sometimes"
I've taken on a prayer practice of looking for the moments of light in each day, whether actual or metaphorical, and then writing or posting photos of what I find.
