Nature photography requires a different set of aspirations and techniques, compared to all other areas.

You need to record scenes as they are, but from the bet vantage point you can find.

The best images are shot to take away distraction and focus the eye on the subject. In cases where you have access to your subject it pays to do your 'gardening' before pressing the shutter.

I have said before that knowing your subject helps. You also need muscles and a bottomless pit of money for all those lenses!
