The total solar eclipse arrives on Monday, April 8, and is visible across Mexico, the USA, and Canada. Catch a glimpse with this DIY pinhole camera.
Here is a finished pinhole projector made from a cereal box, a low-budget way to view the April 8 solar eclipse. To make a box pinhole project, gather up the following items:
The lenses on a camera or telescope can focus the light from the sun, making it even more dangerous, regardless of whether eclipse glasses are worn or not. ... a pinhole projector is another way ...
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 image plane is parallel to axes X1 and X2 and is located at distance from the origin O in the negative direction of the X3 axis, where f is the focal length of the pinhole camera. A practical implementation of a pinhole camera implies that the image plane is located such that it intersects the X3 axis at coordinate -f where f > 0.
A pinhead mirror can be used to create a camera similar to a pinhole camera. Instead of passing through a tiny aperature, the light to form the image is reflected by a small disc-shaped mirror (with a diameter the same as that of a pinhole; about 0.15 mm - 0.4 mm).
Create a pinhole projector to see the partial solar eclipse. With a pinhole projector, sunlight travels through the pinhole to create a small image of the sun. The projector makes it safe to ...
Solarigraph with the sun paths between July 2018 and May 2019 in a street at Valladolid, Spain. Solarigraphy is a concept and a photographic practice based on the observation of the sun path in the sky (different in each place on the Earth) and its effect on the landscape, captured by a specific procedure that combines pinhole photography and digital processing.
