Pinhole photography has it's roots in middle 19th century, in the time of the discovery of photography. It is very similar to classical photography. The difference is in using different type of camera. The pinhole camera is just a box with very small aperture through which light passes, projecting the image on the photosensitive material (film or photo paper).
In these modern times, for me it is a challenge and joy to take photos with the same technology that was used by early photographers. Pinhole photography's style in art is explained as pictorialism and photo-secession.
I made the camera by myself, and I shoot on medium format film (6x6). All films are developed and scanned by me.
