Rainforests in Wet Weather

This is actually the best time to photograph Rain Forests – they look right and the richness and colours show through.
Heavy rain is problematic but light intermittent drizzle is achievable or if it is after rain but still cloudy.
Benefits
Even Light
Sun light in a forest creates many high contrast highlights and shadows. This produces an image that can be confusing and where the subject is hard to discern. In cloudy or drizzly weather, you still have light and shade from the open patches of sky that break through. These are much lower contrast levels, thus producing a better image.
Wet Leaves
Wet leaves and ground create rich colours and wet soil and bark is darker, giving better contrast for your subject which allows it to be more easily seen.
Creatures
Many creatures come out in the moist conditions like native snails & slugs, birds and more.
Mist & Low Clouds
You may be lucky enough to get some mist that gives a beautiful look to your forest.
Water Droplets on Leaves and Branches
These can give beauty and added interest

Downsides
There is less light so ….
Take a Tripod. You need to decide whether you will use a tripod or hand hold your camera. For the best quality images, take a tripod and use a low ISO and a low shutter speed. If the shutter speed is below 1 sec, use a remote trigger or a 2 second timer to delay your shutter, giving the camera time to stop even the slightest movement
or
Use a high ISO and hand hold. The aim is to have your shutter speed high enough so you don’t have camera shake (above 1/60sec for short lenses and at least double that for long lenses).

Keeping Your Camera Dry
Take a small towel to place over your camera if it is drizzling. Use this to dry it also. Watch out for droplets on your lens – they really stuff up a photo!
When you return home, thoroughly dry and air your gear, extend your tripod and dry off all bits.

Enjoy your photos and the experience of being in an awesome place.
