What is a pinhole camera?
Q: What is a pinhole camera?
A: A pinhole camera is a camera without a conventional glass lens that uses an extremely small hole in a thin material to create an image when all light rays from a scene go through a single point.
Q: How does the size of the aperture affect the image produced by a pinhole camera?
A: In order to produce a reasonably clear image, the aperture has to be about 1/100th the distance to the screen, or less.
Q: What is the shutter of a pinhole camera made of?
A: The shutter of a pinhole camera usually consists of a hand operated flap of some light-proof material to cover and uncover the pinhole.
Q: What is Solargraphy?
A: Solargraphy is a type of photography that uses a pinhole camera to capture the movement of sunlight over a long period of time.
Q: Why do pinhole cameras require longer exposure times than conventional cameras?
A: Pinhole cameras require longer exposure times than conventional cameras because of the small aperture. Typical exposure times can range from 5 seconds to hours or days.
Q: How can the image produced by a pinhole camera be viewed?
A: The image may be projected on a translucent screen for real-time viewing, which is popular for viewing solar eclipses.
Q: Is the image produced by a pinhole camera upside-down or right-side up?
A: Like other cameras, the image produced by a pinhole camera is upside-down.
