Image Compression
*
Compare the strengths and weaknesses of different digital image formats. How does the amount of compression affect a JPEG image? What happens when you save a JPEG image multiple times?

Digital Photos and Dynamic Range
Digital cameras can be a great way to learn about photography. Most digital cameras today have LCD screens, so you get instant feedback on your photo. If you make a mistake, no problem, you just delete the picture. It's nice that you don't have to worry about the expense and bother of developing film! This project can help you learn to take better pictures.

Measuring the Speed of Moving Objects with Stroboscopic Photography
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.

Dots Per Inch (Dpi) and Image Quality
*
Your digital photo comprises a certain number of dots in the x and y directions. What happens to the print image quality as you "stretch" those dots out to larger and larger pictures? (Note:...

Seeing Beyond the Visible: Photography with Near Infrared Illumination
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 camera, tripod and a special filter to take pictures using near infrared illumination. It's a whole new way of looking at the world.

Focusing Your Flash for 'Freezing' Motion
Here's an interesting flash photography project. With an inexpensive Fresnel lens, you can concentrate the light from your flash. You'll be able to shoot with a smaller aperture and a shorter flash duration. This will give you greater depth of focus and will allow you to 'freeze' motion at higher speeds. The trade-off is that the light will be concentrated toward the center of the frame. This project shows you how you can investigate that trade-off and find out how you can best use your flash for 'freezing' motion.

Measuring Velocity with a Video Camera
*
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...

Digital Pinhole Camera
If you sit under a leafy tree on a sunny day, you may notice spots of sunlight on the ground from light passing through spaces between the leaves. Try putting a piece of cardboard on the ground and examining the spots of light on the cardboard. Even though the spaces through which the light is passing are irregular in shape, the spots on the cardboard are round. What you are seeing, in fact, are projected images of the sun. Light passing through an aperture forms an image. A pinhole camera uses a tiny aperture, instead of a fancy lens, to project an image. What happens to the quality of the picture as the size of the pinhole is changed? This project shows you how to find out.
