Digital Photos and Dynamic Range

Science Fair Project Idea
Scientific Method
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. Read more
Focusing Your Flash for 'Freezing' Motion
Add Favorite
Science Fair Project Idea
Scientific Method
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… Read more
Image Compression

Science Fair Project Idea
Scientific Method
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? Read more
Macro for Micro?
Add Favorite
Science Fair Project Idea
Scientific Method
If the prefix "macro" means large and "micro" means small, then why will the macro setting of a digital camera help take a better picture of a small object? Do this experiment and get the big picture. Read more
Measuring Height Or Distances with a Camera
Add Favorite
Science Fair Project Idea
Scientific Method
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. Read more
Measuring Speed with a Video Camera
Add Favorite
Science Fair Project Idea
Scientific Method
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. Read more
Pinholes, Light and Aperture Size
Add Favorite
Science Fair Project Idea
Scientific Method
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. Read more
Red Eye
Add Favorite
Science Fair Project Idea
Scientific Method
How does the angle between the lens, the subject's eye, and the flash effect the appearance of red eye? How does the subject's eye color effect red eye? Read more
