f295 founder Tom Persinger writes:

If you’re looking for an event to participate in for Worldwide Pinhole Photography Day, may I suggest f295’s “Simultaneous Pinhole Project” at 7pm GMT 30 April 2006.

As part of Worldwide Pinhole Photography Day, f295 is sponsoring “The Simultaneous Pinhole Project”. A project in which participating members of f295 will make an image at roughly the same moment across the world. Participants will use their pinhole cameras to capture the outside world at GMT 7:00pm. Local times to be adjusted accordingly (eg: GMT 7pm would be 2pm EST, 10am Alaska, 5am Sydney, etc.)

Your pinhole images should contain part of the outside world. If it’s dark in your corner of the globe at the appointed time, feel free to photographlooking out a window with a light/still life in the foreground. The idea is to see the different parts of the world outside at the same moment.

When images are uploaded to the pinholeday.org website please remember to include them in the f295 group. This is a new sorting feature and will allow users to view the series in it’s entirety at the same time.

WPPD 2-day pinhole photography workshop, Providence, RI, US

Nicolai Grossman Leave a comment

David Ellis is leading a two-day pinhole photography workshop for Worldwide Pinhole Photography Day at AS220, a non-profit community arts center in Providence, RI, US. The price, $100 + $35 lab fee, is incredibly reasonable as far as these things go.

"Today, there is a growing interest in pinhole photography, which focuses more on the essence of, and less on the fact of a moment. This fun and exciting “low-tech” approach allows us to accept chance while freeing us from our need to control outcome. It is an excellent opportunity for any artist as well as beginner or seasoned photographers to loosen up their imaginations and explore new avenues of seeing.

"During this two day workshop, we construct cameras made from ordinary containers, take photographs using photographic paper to create paper negatives and use the darkroom to make prints. On the first day, we construct our cameras, take photographs, explore exposure times, learn darkroom processing and create negatives. On day two we use the darkroom to create positive prints. Prior photographic experience is helpful but not necessary. Open to artists from all mediums. Throughout, emphasis is placed on experimentation and process with individual coaching and a final group critique…"

Two days: Sat. & Sun., April 29th & 30th, 9:30am–4:30pm each day.

How-to: 120 folding camera pinhole conversion

Nicolai Grossman 3 Comments

Paul Beard posted a how-to for converting an old folding 6×9 120 Foldex 20 camera to use a pinhole instead of a lens and adding a cable release. Even if you’re an old hand at pinhole conversions, you may want to check out his elegant cable release design.

"After kvetching about the pictures of other camera HOWTOs, I figured I better do a good job on my own.

"Read on for some pictures and text on how to convert an old 120 roll film camera to a pinhole camera, as well as adding a cable release…"

TV commercial shot with a pinhole

Nicolai Grossman Leave a comment

Cinematographer Anders Uhl shot a TV spot for Buell with a pinhole on his movie camera. He wrote:

"The Buell spot was mostly 12 FPS, 180 shutter Ilford HP5+ pushed three stops. I initially tested Kodak TMAX in a 535, but the results were not quite as good as the Ilford, which holds up very well at just about any rating. A freak week long rainstorm drove my exposure down and muddied things up a little (too many greys), but you can get some fairly sharp images if you have sharp contrast and strong highlights."

Technical PDF on optimum pinhole sizing

Nicolai Grossman Leave a comment

Excerpt from by "The Pinhole Camera Revisited or The Revenge of the Simple-Minded Engineer", by Kjell Carlsson:

"The image of a point object, the Point Spread Function (PSF),
should be as small as possible to produce a sharp image.

"Geometrical optics approximation: Hole should be as small as possible.

"Fraunhofer diffraction approximation: Hole should be as large as possible.

"No optimum size is found!

"Conclusion: The optimum size is found in a region where neither geometrical optics nor Fraunhofer diffraction is valid!"

For the more mathematically inclined, this paper discusses the preceeding conundrum and has simulated sample images for various pinhole sizes. I can’t follow the math, but I found it an interesting read nonetheless.
