Some quotes from the book:
Taking a good butterfly photograph not only yields a feeling of achievement, it also provides enhancement to the appreciation of the beauty of nature. Every moment captured is unique and irreplaceable. It is harmony with nature. The living butterfly is our best model and nature furnishes the perfect background.
A good butterfly picture not only tells us what the butterfly looks like, with the most vibrant combination of colours and patterns, it also displays the very spirit of butterflies that can touch one's hearts. Butterfly photography is an art. It provides an opportunity for us to exercise our imagination, emotions and creativity.
There is no hard and fast rule for getting a superb beautiful photo on par with professionals. Behind every success there are many unsuccessful attempts. We learn by trial and error. Practice and patience make perfect.
