Dewdrops are one of my favorite subjects. Each one has its own unique beauty. This drop appealed to me because it looks like a delicate dipper filled with smaller drops. It is actually one large drop on the bottom and several small drops on the top of a tiny blade of grass.
I find late summer is the best time to capture dewdrops as the lawn is laden with them in early morning, but they linger for a while after the sun rises. In the heat of the summer, the dewdrops dry up quickly when touched by the morning sun.
If you want to try your hand at photographing dewdrops, get out the macro lens and head for the lawn or other grassy area in the early morning. Be prepared to change settings often as the light changes drastically from one spot to another. It is also best if the air is still. The slightest movement from the wind can knock a macro shot out of focus.
Good luck!
