Today is World Pinhole Photography Day for 2021! Snap your pinhole photos today and upload to http://pinholeday.org/.
You have until June 30th, 2021 to upload your photos, but the photos must be taken today.
There are many options, from a shoe box to a pinhole lens, such as the Thingify Pro S lens and anything in between. It is even possible to make your own pinhole lens with a modified body cap or lens board on a camera and a piece of foil.
Enjoy!
