Check out some of the amazing work at Worldwide Pinhole Photography Day.
For 2020, I’m doing an extremely-long-exposure photograph or solargraph. The Worldwide Pinhole Photography Day rules are that the photograph must be taken “on the day annually designated as Worldwide Pinhole Photography Day ( April 26, 2020 )” or “Extremely long exposures will be accepted if any part of the exposure was made on Worldwide Pinhole Photography Day…”
I started the exposure on 1 May 2019 and I want to do a full year. That means if the exposure is a bust, I’ve missed WPPD and I’ve got nothing.
So… I decided to make another pinhole camera and use a scanner. I used a USB powered Canon LIDE 30 as a digital back and VueScan and TWAIN-SANE software. The results are not a supreme victory but first, the camera.
JPEG from a PDF page print from http://mrpinhole.com/. I used 8×10 inches as the portion of the 8.5×11″ scanner in case I had to resort to paper. The 16″ film dimension is insurance and a trade off to get the specs I wanted.
I’m up late and it’s actually May 1st. At about 3:00 PM local time I’ll cover the shutter and find out if the long exposure worked.

I actually have a 4X5 developing tank. I got it when I bought most of a darkroom from a guy in Santa Fe. He’s getting out of film photography to concentrate on restoring an old Lotus. Sometimes you have to choose and whichever passion is pulling you the strongest wins. Any way, it’s cool but it’s made to do a bunch of sheets at once and it takes a LOT of chemicals. So, I used the “taco” method to develop. You fold, well, gently bend, and put a hair tie around the film to keep it from coming undone. The Yankee tank I usually use wasn’t quite deep enough but I also got a Paterson from the same guy and it clears the 4″ height of the negatives. No reels but you have to keep in the center cylinder so it’s light tight. You can squeeze in 4 tacos but I only had the three to develop.
There’s a good taco development visual how-to on Flickr by Tony.
I’m nearly caught up! Well, I have to scan two rolls and develop and scan another but that’s pretty close to caught up.
Links mentioned in the video:
A chart from Mr. Pinhole showed 2.5 minutes. My meter app showed 1.5. We split the difference at 2 minutes and ended up overexposed. It was bright out.
The scanner at work, a Canon print/scan/fax thing, was giving me bad reflections from the clear plastic on the Instax frames so i had to adjust. They’re underexposed to start with — f/256 is pretty dim.
1200DPI scans on a CanoScan 9000f. I scanned in color and decided to leave them that way.
The scanned images in the video and the ones posted here are unedited except for resizing. The negative scans had levels adjusted before reversing to positive. It’s kind of a cool effect doing it that way — I just have to reverse my thinking to imagine what it will look like.
I haven’t scanned the Socorro Peak negative yet. I put it between two pieces of paper to protect it not realizing it still had wet developer goo on it. I washed off some of the emulsion with the glued-on paper.
Some people have gotten sharp images using pinhole cameras. I’m not there yet. I’m going to try more experiments and not wait until the week before next year’s Worldwide Pinhole Photography Day to cobble something together.
Shot for Worldwide Pinhole Photography Day, 26 April 2015.
Expired Kodak 400 film processed and scanned by my good friends at The Camera Shop Of Santa Fe.
I didn’t think to factor in the short lens to film plane distance so the image circle doesn’t cover the 35mm film frame.
The image I submitted:
Some more from the second roll (also expired Kodak 400).
The next three were taken at the Classical Gas Museum in Embudo, NM.
I didn’t end up using the digital camera (Canon 60D) as much as I thought I would. Most of the shots with the Bell+Howell, I winged it.
The conversion was pretty straightforward — The metal pinhole from the cardboard camera from last year taped to a T-mount lens adapter for the Canon. I only used the needle to make sure the hole was clear and clean of cat hair.
My favorite shot from the Canon. I think the pinhole is larger than necessary so the kit will give something to a kid using the Ridley camera.
Worldwide Pinhole Photography Day is April 26, 2015.
No video for this one. This is the plastic fantastic Bell+Howell Ultra Compact 35 (28mm) reborn as a pinhole camera.
By keeping the unmodified shutter actuator, I still have the interlock. As soon as I open the cover, light will hit the film through the pinhole. I need to hit the shutter button while the cover is open to allow wind-on and the frame counter, and then close the lens cover to end the exposure. I have no idea of the diameter of the pinhole and hence no idea of the f-stop. Like last year, I’ll cheat a little and use a pinhole on the 60D in aperture priority mode, set to the same ISO as the film in the Bell+Howell, to get a shutter value. Add a little time for reciprocity failure if needed and hopefully I’ll get some decent exposures. I haven’t decided on film but I’ll probably use a 36 exposure roll so I can bracket like crazy and maybe get 12 usable shots. Time to hit the freezer and see what I have.
I used expired Kodak Max 800 (02/2003).
Mixed results. The exposure isn’t bad — I set the Canon with the pinhole lens to ISO 800 and used its shutter time to ballpark the timing for the cardboard camera. I didn’t stabilize myself well enough so there’s a lot of blur. There’s a lot of frame overlap too so I had to scan by hand and crop the overlap. The directions said to use 1 1/2 turns for the first ten frames and single turns after that. It wasn’t enough — the pinhole camera laid down some pretty wide pictures.
I was about half way through the roll when we stopped at a rest area on I-25. Crazy windy. The wind blew the camera out of my hand and it pretty much exploded when it hit the blacktop about 50 feet away. I put it in the dark bag and rolled the film back into the canister but the damage was done. I got about six frames that weren’t obliterated when the camera cracked open. Surprisingly, the last frame (the last picture below) wasn’t ruined.
Pretty sure the light leaks are from the explosion. I had this baby taped up pretty well.
