A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called pinhole)—effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect.

The pinhole camera is the simplest kind of camera. It does not have a lens. It just makes use of a tiny opening (a pinhole-sized opening) to focus all light rays within the smallest possible area to obtain an image, as clearly as possible.

2022年3月14日 · You may be asking what is a pinhole camera (or how to make a pinhole camera!). In short, it's a camera that is stripped back to its most fundamental elements. Basically it's nothing more than a lightproof space with a hole – which is the aperture – perforated into it.

2023年7月18日 · A pinhole camera, or a camera obscura device, is the simplest camera possible. It consists of a light-proof box, some sort of film and a pinhole. The pinhole is an extremely small hole like you would make with the tip of a pin in a piece of thick aluminum foil.

2024年10月11日 · Learn how to make your very own pinhole camera to safely see a solar eclipse in action.

A basic pinhole camera is a light-tight container with a tiny hole at one end, and a piece of photo-sensitive material at the opposite end. Light passes through the pinhole and the photons cause a chemical change on the film, resulting in an image being produced.

A pinhole camera is a simple, safe and free solution that will allow you to watch a solar eclipse — and all you need are a few basic household supplies. According to NASA's Jet Propulsion ...

2014年4月11日 · Pinhole cameras rely on the fact that light travels in straight lines – a principle called the rectilinear theory of light. This makes the image appear upside down in the camera. One thing that inspires many pinhole photographers is the craft of building their own cameras.

2023年7月24日 · Pinhole cameras have an incredibly vast depth of field, ensuring that both nearby and distant subjects appear in focus. Pinhole cameras do not require complex lenses, making them more accessible and affordable for photography enthusiasts.
