I chose my camera (Nikon D300) mostly for its dynamic range. That means that in very contrasty situations (like rainforests) I get a lot more detail in the darkest and lightest sections of the photograph.
These are photos that I just couldn't have taken with my little Canon Powershot A85. Not that my Canon hasn't served me well and continues to do so, but before I bought the Nikon, I had been getting disappointed with the limitations of the Canon. I knew what I wanted it to do and it just couldn't do it.
Mummy McTavish liked the prickly photo. It's a palm that grows as a vine (or liana) and can climb to the tops of trees. I can just imagine Tarzan getting a handful of those spines as he swings through the trees.
