The pinhole is a version of the camera obscura—a method of reproduction that dates back thousands of years and, in (relatively) modern times, one of the earliest forms of photography. Modern photographic 35mm lenses often have apertures that stop down to f/22 or f/32.

Like our eyes, cameras register light. Light travels in straight rays from the object producing or reflecting it. In the 5th century BCE, the Chinese philosopher Mozi (470 – 390 BCE) first documented the curious effect of camera obscura(Latin for “darkroom”). As light traveled through a small hole into a dark space, the outside image appeared flipp...
Film is the perfect medium for pinhole photography. The sharp quality and elegant contrast of black and white film produces stunning images. However, almost any type of film can be used, and it is worth experimenting with Kodak, Ilford, and Lomography stocks. Direct positive photographic papercan also be used and is particularly well-suited to larg...
Already have a DSLR camera? Pinhole photography is not just for film. Thingfy‘s lenses fit most of today's cameras, and unlike with film, your results are viewable on the spot. Keep in mind your lens mount and sensor size, as well as if you would like a shorter focal length for a wider field of view. You can also take a body cap and make your own p...
Dec 6, 2023 · The formula is: focal length = (pinhole diameter / 0.03679)2. The focal length is the distance that the pinhole should be from the film. Example using 0.3mm pinhole: focal length = (0.3mm / 0.03679) 2. focal length = (8.17438) 2. focal length = 66.49mm. The next value you need to calculate is the view angle of the pinhole.

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.
Jul 9, 2015 · A simple, lightproof camera without a lens, typically a small box or container with a tiny aperture (pinhole) on one side. Light passing through the pinhole projects an inverted image onto the opposite surface inside, capturing a photograph.
Mar 14, 2022 · How to make a pinhole camera. You can make a pinhole lens for any DSLR or mirrorless camera by drilling a hole in an unwanted body cap, then covering it with foil that contains a tiny pinprick hole. A pinhole camera can be made with little more than a shoebox and a needle to add your aperture, although it pays to paint the inside of your box ...

Apr 29, 2024 · The optimal pinhole size is the diameter that allows for the sharpest possible image. It balances the diffraction of light (which spreads light rays out and blurs the image) with geometric sharpness. This optimal size can be calculated using a straightforward formula derived from physics principles. Below a popular formula, standard sizes ...
