I was looking for water drops after a heavy rain in the yard last year. I saw this leaf with lots of different size droplets and photographed the leaf with a close focusing 300mm f/4 in 2 horizontal images stacked. I used Photoshop to combine the images and then brought out more detail in the Drops. Then went on to photograph the water drops on leaves. I also used a High Pass sharpening technique on a separate layer in Photoshop.
