I find this type of photography both exciting and challenging. The challenging part makes you think more about the composition because you really have not idea of what the camera is actually seeing.
For my ongoing Pinhole Photography project, I use a Zero Image 2000 camera which has a pinhole of 0.18mm in size and produces a 6x6cm square negative.
I use a variety of black and white films and each roll is hand developed in either Kodak Xtol or Kodak HC-110 developer.
They are then scanned on an Epson scanner and archived for printing.
The majority of prints I make from the Zero Image Pinhole Camera are mainly printed between 7 and 10 inches square.
