A date with nature

Yunsong started to learn photography from Zheng two years ago with a digital single-lens reflex camera.

"I enjoy the process of taking photos. I like to hear the sound of shutter clicks. I'm blissfully happy when I capture a good picture," says Yunsong. "Whenever I see a photo, I will recall the moment when I took it.

"I like taking pictures of wild animals because I like the uncertainty. You never know what will happen the next second."

Zheng says each time they observe a wild animal, the only sounds they hear is the click of shutters. He teaches the parents and children how to take the best photos possible, and he believes photography is a great vehicle for communication.

For the experts, these trips offer the opportunity to learn about nature education in other countries, and they often return home with illustrated handbooks of the wildlife they have encountered abroad. They enjoy guiding tourists because they want to pass on their knowledge, and they also relish the chance to encounter animals in the wild.
