Before the age of smartphone “selfies,” drone cameras, and the instant gratification of Instagram, there was there was the pinhole camera.

Pinhole photographers from around the world celebrated World Wide Pinhole Photography Day on Sunday by showing us the beauty in the photography’s most basic form.

With origins tracing back 2,500 years, Pinhole cameras can vary from a homemade tin can to a digital camera with a hole drilled in the body cap. All pinhole cameras share the same basic mechanics: a light-tight box that uses a small hole for a lens. Photographer Justin Quinnell, who uses the pinhole process in his work, told The Post last year:

“Pinhole seems to be finding a new following in people who want to discover the world rather than pay for instant answers.”

Worldwide Pinhole Photography Day is celebrated on the last Sunday in April. Pinhole photographers from around the world upload their images to the event organizers’ online gallery. What started in 2001 has grown to more than 3,000 submissions from over 70 countries in each year. Here’s a selection from Sunday’s celebration:

CAMERA/PROCESS: Taken with an instant pinhole camera kit made by Polaroid using Fuji FP100C. The image exposure took roughly seven minutes. The rough border around the photo comes from my preferred method of peeling my instant photos backwards, leaving the black frame and some of the developer “goop” around the image.
