Worldwide Pinhole Photography Day

April 27th was Worldwide Pinhole Photography Day. I have been participating for the last few years with a pinhole camera of some sort. I enjoy making photographs with pinhole cameras because they are so simple and create these incredibly dreamy and unpredictable photographs.

This year I procrastinated, although I knew what camera I was going to use. It is a Whitman's chocolate box sampler that I knew would make a perfect pinhole camera.

I didn't do much to modify the camera, just a bit of red paint inside to insure the light wouldn't bounce around and expose the paper negative. I should have used black paint, but alas it was a last minute build the day before I was going to shoot with it, so I used what I had in the house.

 The pinhole was made with a push pin and a Coke can, affixed to the camera with some electrical tape.

I decided that building a camera at the last minute wasn't enough of the challenge, I was going to try a developer I had never used before in pinhole photographs. I mixed up some Caffenol CM developer that would normally be used for developing film. I love this developer because it is so environmentally friendly. The ingredients are water, washing soda, vitamin C and instant coffee.

After setting up the temporary darkroom in my downstairs bathroom, I mixed up the ingredients for the developer and started loading the camera. I brought in my small paper trimmer because I thought I would have to cut down the photo paper I was using as a negative. Alas a 5x7 sheet of photographic paper fits perfectly in the back of the camera! Again a lucky discovery. Four pieces of tape in small loops held the paper firmly in place during the exposure.

Outside I went, and I had no idea what the exposure would be, or how the paper negatives would react to the Caffenol CM developer. I guessed my exposure at one minute fifteen seconds under mostly sunny almost midday skies and returned to the darkroom to take a look a the first image. It is a little strange developing paper in a developer that looks like Guinness, but after about 70 seconds of agitation my first negative came out, and it was perfect! I really was doing well with this camera build.

I was able to fit in five exposures before having to call it quits. Of the five negatives, only one was blurry due to the winds picking up at the tail end of my shoot and blowing the camera around. So how did they turn out? Very well indeed! This to date has been the easiest pinhole camera I have built. The negatives came out sharp and contrasty, the camera had no light leaks, and I was very impressed with the results.

I scanned all the negatives and flipped them to positives in Photoshop. The negs only needed slight tweaking, and just a bit of sharpening. Overall the images were very sharp. I loved the blurry trees and moving limbs, since it was windy that day and anything moving during the minute and fifteen second exposure would be blurry.

First exposure is off the deck looking into my back yard. The round spot is where the pool will go up again later this year.

Second exposure is of a happy dandelion growing in my vegetable garden framed by trees and sky.

Just to try out another new technique, I decided to try and make a cyanotype of my paper pinhole negatives. This was the biggest struggle of them all. The paper of the negative blocks a lot of the light from going through which made the exposures very long. I have a small indoor UV lightbox I built to make cyanotypes and even at four hours of exposure I still only had a faint image.

I took matters into nature's hands, and made the cyanotype outdoors using regularly available sunshine. Even with direct UV light from the sun, it still took 2 hours of contact printing to get decent results.

 Overall this was a fun project, and I have yet another fun pinhole camera to use again.

Here is a link to the website, and a link to my submission this year.  It is submission #1862, which is a perfect number for me!
