Butterfly and Yellow Flowers

In May 2008, 20 students participating in a National Geographic Photo Camp workshop got a unique assignment: Document and photograph a 24-hour BioBlitz in California's Santa Monica Mountains. The students, from EcoAcademy High School in Los Angeles, chronicled the event from setup through the closing moments, joining scientists and volunteers as they combed the park counting species.

The group produced hundreds of images, including this photo of a colorful butterfly sipping nectar from a flower.

"It was really just a great experience," said participant Richard Kelley. "I know I'll never forget it."

When making long exposures, use a remote release to avoid camera movement. If you don't have a remote release, use the camera's self-timer.
