How Does a Photography Bellows Work?

With the right camera and supplementary equipment, you can capture any subject. Most people wouldn't have the first clue about taking pictures of something such as a fly or a tick in a close up, however, it can be done. Rather than buying expensive lenses and high-end, powerful cameras, use what's called a camera bellows. While it might look silly or old fashioned, the bellows is an invaluable tool for those who want to take big pictures of little things.

Traditional Bellows
- A bellows is a device that attaches to the front of your camera. The lens goes on one side, the camera body on the other. The bellows can be extended and its angle is adjustable. Bellows come in an accordion-style attachment, which is ribbed like the center of an accordion, or a bag bellows which narrows closer to the lens.
Function
- A bellows is used to help minimize distortion in a photo and to provide additional focus. As you pull the lens away from the film or plate, the additional distance allows for clearer photos. Since the bellows is completely black inside, it doesn't affect exposure. This distance is similar to that provided by different types of lenses. The bellows is less expensive than a traditional closeup or zoom lens.
Macro Photography
- Technically, any type of close-up photography is considered macro photography. Macro photography refers to taking detailed, close-up photos of small things such as insects, the insides of flowers and medical specimens. To eliminate distortion, a combination of bellows, extension tubes and high-quality lenses are often used.
Advantages
- A bellows achieves a simple operation that has been used since the early days of photography. Bellows are light weight, bendable and help alter the angle of a photo without worrying about damaging your camera accessories. Bellows are inexpensive compared to extended lenses.
