If you know or calculate the field of view for your camera, you can use it to measure distances and the height of almost anything. It's all a matter of basic trigonometry.

A video camera records 30 "frames" or distinct images per second. (That's for an NTSC camera in the U.S. PAL cameras in other areas of the world take 25 frames per second.) You can use this fact to time events and measure speed. One student has used a video camera to measure the speed of an arrow shot from a bow. The following project can help you set up your experiment: Distance and Speed of Rolling Objects Measured from Video Recordings.

A strobe light can illuminate an entire room in just tens of microseconds. Inexpensive strobe lights can flash up to 10 or 20 times per second. This project shows you how to use stroboscopic photography to analyze motion.

Pinhole cameras are not just for grannies! Even compared to all of the latest technology, a pinhole camera still gets beautiful results. Find out how this very simple aperture design works to control the way light enters the lens of your camera.

Have you ever wondered what it would be like to have an extra sense? What if you could hear above the normal range (ultrasound) like dogs or bats? What if you could see ultraviolet light, like bees or juvenile trout? What if you could see infrared light, like a rattlesnake or boa constrictor? This project shows you how you can use a phone or camera, tripod, and a special filter to take pictures using near infrared illumination. It's a whole new way of looking at the world.
