Pinhole Photography Day


Worldwide Pinhole Photography Day is April 29th this year, and the promoters encourage everyone to try out pinhole photography.  The website   http://www.pinholeday.org/    gives the basics of pinhole photography, and provides tips and instructions for making your own pinhole camera.  And a quick search shows gives many other resources and galleries on the web related to pinhole photography.

It's probably cheating to use a digital camera for pinhole photography, but I tried some photos with my Pentax K20 and a Lensbaby pinhole lens.  See the photos below.  I'll have to do some experimenting with the pinhole size to see if I can get the images a little sharper, but that may not be possible on such a small format camera (APS-C sensor).


















Morro Bay Harbor by pinhole
















Emergency Vehicle Show - Morro Bay - April 20 and 21

Photos were taken with Pentax K20 digital camera, and Lensbaby pinhole optic.  The pinhole is 0.3 mm - f176 - and the focal length is 50 mm - I added a 0.6 x wide angle adapter.  Pictures were metered at f22 then shutter time increased by a factor of 6 to get the correct exposure.  Digital preview gives near instant results of the pinhole exposure and composition.

  1. Nice pics and good info what pinhole sizes ans focal length you are using. But I wonder: Why are you using a lensbaby? What adventages does it have?
    I myself use a Canon 5D with a selfmade pinhole lens holder made of a camera cap and old plumbing gear (garden hose connection), and exchangable pinhole lenses in different sizes (0,1 up to 0,3 mm). The lenses I use are made of alu-and brass-foil, or 0,05 mm thick stainless steel (old spark leveling tool) (www.pinhole.org)
