Here's a top tip.
If you go into the tropical rain forest, be careful when you take your camera out of your bag. It may not seem like it, but relative to 35 degrees and 100% humidity, your camera is freezing cold. It will get covered in condensation immediately. Harrumph.
Anyway, what do you think of these green things? They are about a meter across BTW.
What fantastic design, all that folding.
