Pinhole Challenge

January 25th, 2021
Create a pinhole image with your digital camera.


I know, what is he thinking? This is a unique challenge that hopefully will take hold. Pinhole photography is random and fun. The image below was taken by me with a film pinhole camera. In filmdom, a pinhole on a production camera is a thin metal disc with a very small hole drilled into it. One opens the "shutter" by uncovering the disc and closes it by covering the disc. Pinhole cameras come in all shapes and sizes. People make them out of shoe boxes, soda cans, you name it.

A pinhole lens can be made from aluminum foil or a square cut from a beer can, and a sewing pin. Because of the small size of the "aperture" (mine was over F150) longer exposures are required depending on the chosen ISO or film ISO. This exposure was I think around 4 - 7 MINUTES...(NOT SECONDS).

Because of the extremely small aperture, EVERYTHING IS IN FOCUS FROM RIGHT IN FRONT OF THE CAMERA TO INFINITY.....

Here is my image.

The largest image ever taken was made using an aircraft hangar as a pinhole camera! Leonardo DaVinci used them too.

To bring this challenge full circle, here is how you make a pinhole lens for your digital camera. It is easy using materials available at home and a spare body cap.'

Here is a discussion of digital pinhole imagery on B&H Photo.

I will leave the challenge open until 5:00 p.m. US EST on March 1. Have fun!

i made a cap , so i will try to find it, i think my hole is a smidge off-centre so the vignette is not even, i might try again.

my sensor is hella dirty... just read a good tip to use a polarising filter overtop to punchify the colours.

@kali66 It should be fun. Time will tell on participation, this will take a bit of effort and patience. If you get a chance, check out the work of Zeb Andrews with film pinholes. It is amazing. Where you are, a soda can solargraph would be a wonderful option. Easy to make with a few beer cans and some tape and a piece of photographic paper. If you want to try it, I can send you some 5 X 7 paper. This is the method Jesus Joglar uses. Google him, amazing too. I have been meaning to make a solargraph, so this is my spur. Some of his exposures last a year.

Modern camera stores will pro clean the sensor for not much money. My shop does it for $35US. You can also get a kit to do it yourself, but be careful. I have done it and it's not difficult.

@brotherone i have some photographic paper, i wonder if you could do it with cyanotype paper....

I suppose you could. You would have to know what the ISO of the paper is and expose to that. Or just wing it. Take your exposure for sunlight and just multiply it using an F Stop of 200. Remember, Jesus' exposures are for 6 months to a year. Pick a sky orientation that captures the rise and fall of the sun best...I have never done it. Also, you'll have to put the camera in a spot if outside that will be safe. I have a shot he sent me in my office that is from inside, through a window and was a 6 month exposure from May to November. I will send you a picture of it tomorrow.

@brotherone @kali66 I clean my sensor. I think it must be to frequently lens changing.

I will give this a go when bright light reappears here!
