After the rain
Raindrops are fascinating through the lens. Try photographing them from various angles, and in different lighting. When photographing a single droplet, or a string of them, isolate them by keeping the background uncluttered. You can do this by creating distance between the droplets and the background, and using a wide aperture to ensure it is blurred. Notice also how water sits in nice round droplets on some types of leaves, but on others it disperses.
Mushrooms, toadstools and fungi
These are abundant in autumn and winter, but some species pop up throughout the year after rain. Look in damp, mossy places, on the sides of trees and log piles for them.
My personal favourites are the red toadstools with white speckles. They are evocative of fairy tales and magic, and their colours are a nature photographer’s dream!
Don’t ignore the tiny, dull-coloured mushrooms and fungi. The ones in the photo below were growing in a crevice in the side of my herb garden. You can see by the scale of the woodgrain how tiny they were. From above, they were nondescript, but when I lay on the ground beneath them and shot into the backlight, they became translucent and I could see their delicate structure.
