I consider the most important thing is the well-being of the animals and birds that I'm photographing.
This means that I strive to put animals and their habitats before my own ambition as a nature photographer.
It's easy for a nature photographer to want the 'perfect shot' and overstep the mark and it can be difficult to judge where to draw the line.
Wild animals and birds are individuals and all behave differently, sometimes an animal may look unconcerned by the photographer and be happy to sit and pose.
But go too close and the animal will run, or sometimes (with larger mammals) attack you.
Frightening birds or animals is never a good thing as it causes them stress and may lead to injury, or worse
Here are a few of the basic rules, I follow.
