Image caption, Each week we publish a gallery of readers' pictures on a set theme. This week it is on pinhole photography and we begin with this image of a tree by Ben Smart. It was taken using an old Holga camera that has been modified into a medium format pinhole camera.

Image caption, Diane Peterson: "I am an avid pinholer from the United States, Idaho to be exact. I make pinhole cameras every week. I just see a box or tin and know it has to become one. This image was made from a rather small 4x4" metal cookie tin, circa 1954. Focal length six inches, which is a bit far but I was happy with the results."

Image caption, Christopher Oven: "This was originally taken for my exam topic in photography. I used multiple exposures to help determine the amount of time and detail in each image. I also used bits of twigs and straw which are placed in the homemade pinhole camera, to create a photogram on top of the image."

Image caption, Sarah Mawdsley: "Shot on Worldwide Pinhole Day with a Nikon D800 plus a body cap pinhole. ISO was bumped up to ensure a grainy image and I then converted it to black and white. Taken in Finland, near to Tampere."
