Last month I wrote a piece for The Magazine about glass-lens vs. pinhole photography, and a little $40 accessory my brother-in-law manufactures and sells that allows you to take old-school, genuine pinhole snapshots using high-end Micro 4/3 digital cameras. The article is currently available for free reading over on The Magazine‘s website:
Light Motif — The Magazine
A lens creates a sharp image by gathering photons and directing them toward its focal point. Collecting more light reduces exposure times and noise, creates brighter images, and increases detail. But a lens bends the light it gathers; the image it casts is not true to the object. The most obvious example of this is the barrel distortion created by a wide-angle lens.
You and I both know that no architect designed a roofline with that curve, and no masons tried to build it that way. This image is grossly distorted, but every image coming through a lens has at least subtle distortions corrected by optics and electronics.
A pinhole camera creates no such distortion because it never alters the path of any photon. Instead, it sharpens an image by massively reducing the number of photons that reach the image plane. Blurriness, in part, is caused by a “point-to-patch” correlation between object and image, where photons striking a given point on the object scatter at slightly different angles and thus strike over an area of the image plane, rather than at one point. By blocking these stray photons, the pinhole brings us closer to an ideal point-to-point correlation between object and image.

FYI for Writers: The Magazine has been a great publication to work with, as a freelancer: Good pay, good editors, an excellently fair contract, and really solid exposure and promotion of your work. If you’ve got an article in your that suits them, you owe it to yourself to pitch it.
