About Worldwide Pinhole Photography Day

Worldwide Pinhole Photography Day is an international, non-commercial photography event held on the last Sunday in April.

Participants make lensless photographs and may share one image with the event’s online gallery under its participation rules.

Why Worldwide Pinhole Photography Day matters

The day celebrates the deliberately simple process of pinhole photography and the international community around it.

Participation does not require expensive equipment, but safe handling of light-sensitive materials, tools and viewing conditions still matters.

History of Worldwide Pinhole Photography Day

The idea was proposed by Hong Kong pinhole-camera designer Zernike Au in February 2001, after which an international volunteer committee formed.

The first Worldwide Pinhole Photography Day took place on 29 April 2001; the organizer’s archive contains a 2001 gallery and the event has continued annually.

The current organizing site states that the event is held on the last Sunday in April and is administered by a coordinating team.
