rose – pinhole lightpainting (Ilford Pan F Pro 50)

You have tried light-painting, you have tried pinhole photography. Have you ever used pinhole to do light-painting? Yes, it can be done. Instead of a torch light try a normal flash. For this image of a rose, a flashlight (guide 18 strength) was fired 30 times from a 20 cm distance. Be aware of the direction of the light to emphasize contours and highlights as you would do in light-painting.

Camera: Chamaeleon Panorama 6×12 Serial #126
Film: Fuji Superia 100
Exposure: 6 seconds

in some situations it is impossible to measure or calculate the “correct” exposure and you have to rely on your luck and intuition. Here the camera was aiming against the setting sun with partly illuminated interior and and brightly lit exterior.

Pinhole Exposure Table for DSLR / SLR cameras

One of the most useful tools for the pinhole photographer is the Pinhole Designer by David Balihar. The exposure table below has been created with this tool.

The calculated values include allowance for reciprocity failure of mentioned films. If you are using a Skink Pinhole Pancake with a DSLR camera, the exposure table will give you an idea how to get started. When taking your first pinhole photo with a DSLR camera you can try this for a quick start:

  • Take your camera out on a sunny day and place it on a tripod
  • Choose ISO 200
  • Set the camera to AV mode or A mode (Aperture priority). The camera will measure the exposure through the pinhole lens.
  • Set the camera to manual mode if aperture priority mode is not supported, choose 1 second exposure
  • Bracket exposure and make adjustments
