Pinhole Photography Day

Story location: Home / photography / pinhole /
27/Apr/2015

It's been quite a long time since I posted any non-food photos (back in September when I dabbled with some HDR images), and I haven't done any pinhole photography since 2008.

Yesterday was Worldwide Pinhole Photography Day so I decided to have another go, this time in colour and digital (most of my previous pinhole work was medium format on black and white film). I made a pinhole 'lens' by drilling a hole in a body cap and taping some foil over the hole. I made a hole in the foil using the thinnest needle I could find.

I did a few test photos indoors before going out for a walk along the canal. Since I didn't take my tripod with me, I set the camera to maximum sensitivity to keep the exposures short. Most of the outdoors shots were between 0.5-2s so I still had to brace the camera against something solid but they came out ok.

Pinhole Photography Day

Story location: Home / photography / pinhole /
29/Apr/2008

Sunday was World Pinhole Photography Day, where photographers are invited to take photographs using a pinhole camera.

These photographs were all taken over the weekend. Since they were taken on film, it took me a couple of days to develop the negatives, scan them in and prepare them for uploading.

More pinhole photographs from Coventry. These photos were all taken around summer/autumn last year but didn't get uploaded at the time. Colour photographs of the same scenes are shown for comparison.

Spon Street and Spon End

Story location: Home / photography / pinhole /
16/Sep/2006

Spon Street in Coventry contains a lot of the medieval building in the city, some of which were moved there in the 1970s. During daylight hours the street is usually full of parked cars. These photos were taken early on a sunday morning to try to avoid too many vehicles.

Coventry Cathedral

Coventry Cathedral, build in the 1960s, stands next to the ruins of the 14th Century St Michael's Cathedral. The old cathedral was heavily damaged by German bombing in 1940 and now only the shell remains.

The photographs below compare B&W pinhole photos with colour photos taken from the same position.

The images here were taken with my two pinhole cameras: the pinhole modified Lubitel medium format camera and the Nikon FM pinhole 'lens'. The increased film size of the Lubitel gives better resolution than the 35mm pinhole camera.

Making a Pinhole Camera

Story location: Home / photography / pinhole /
18/Jan/2005

After reading an article on the web about pinhole cameras, I decided to make my own pinhole lens to fit on my Nikon FM. I had a look at some articles on the internet for inspiration, but most of these concentrated on building entire pinhole cameras. I already had a perfectly serviceable camera so I decided the best course of action would be to simply make a pinhole lens for it.

Diagram of pinhole lens construction Making the lens would be fairly easy - this was simply a disc of cardboard with a hole cut in the middle. I then sellotaped foil across the hole, and made a smaller hole in the foil with a pin. The only remaining problem would be attaching the lens to the camera. I realised that the t-mount that I use for astrophotography could be attached to the camera, and the lens could then be attached to the mount.

The focal length of the lens can be adjusted by using a different length of cardboard tube - the actual focal length being the distance from the pinhole to the image plane. The lens as shown in the diagram had a focal length of 100mm and an aperture of approximately f/100 (the actual aperture was measured using a magnifying glass and a ruler.

Aperture=focal length/diameter (mm)

Metering the exposure can be tricky with such a small aperture. Most cameras will allow TTL metering with such a lens, but an aperture of f100 may be too slow for accurate results. The Nikon FM is only suitable in bright conditions because the shutter speed doesn't go below 1 second - slower speeds need the B setting. The Nikon F70 is ideal for this purpose. Selecting aperture priority auto exposure, and covering the eyepiece (to stop stray light affecting the metering), reasonably accurate exposures may be obtained. The camera thinks a manual focus lens is attached, with the aperture fully open, and meters accordingly. Reciprocity failure will rear its head for exposures over 1 second, but with negative film this shouldn't present much of a problem with 'shortish' exposures of about 5 seconds.

If TTL metering is not available - which may be the case for some autofocus cameras (such as the Nikon F50) then a separate hand held meter can be used. If you are lucky enough to own one which goes down to f100 then a straightforward meter reading may be taken. If, like me, your meter only goes down to f22, then a reading can be taken at that setting, and a correction factor applied to the shutter speed. In this case, f100 is just over 4 stops less than f22 (following the sequence f22,32,45,64,90 etc), so I divided the shutter speed by 4 e.g. a reading of ¼s at f22 is just over 1 second at f100.
Recently, I have moved up to medium format for my pinhole work. This was done using a simple modification to an old Lubitel camera. I took it apart and removed the lens! The lens quality wasn't very good, and as I recently bought a second hand Yashicamat, I no longer needed the Lubitel (it had actually been sitting in the back of a cupboard for several years, gathering dust).
Removing the lens was remarkably easy. It was a simple triplet, with the elements held in place using clips. I placed a foil pinhole at the front of the camera, and set the shutter speed to B. The aperture was about f/160. View the pinhole photos
