Yet another Agfa Clack? This time we’re going to try a pinhole conversion.

My experiments with pinhole photography have never been really satisfactory. Firstly there was the pinhole option on the Diana F+, and then I discovered digital pinhole photography and the worst lens in the world, the Thingyfy Pinhole Pro. Yes, I could have bought myself a dedicated pinhole camera, like the Ondu or similar, but I really wanted to make my own.

Actually, I’ve had a home-made wine box pinhole camera on the go since, I don’t know when, but I’m not sure that’s never going to be finished. Which brings me to the Agfa Clack. To date I have three Agfa Clacks. There’s my ‘original’ Clack, the one I bought first and used for the Frugal Film Project in 2023. The second was bought to flip the lens, but the film wind-on knob was broken and I’ve never used it, and the third I added to replace the second one and flip the lens, which worked beautifully.

Back in the woods with my favourite old tree and a flipped lens Agfa Clack.

But now I’ve added a fourth to my collection and one might wonder, what on earth for? Well this time I would like to convert the venerable Clack to a pinhole camera, quite a common thing to do, so far as I can tell. Of course this one was in the ‘Not Passed’ category of the Kamerastore website, and is described as having ‘a significant amount of dust inside the optics that will affect image quality, but it is otherwise functional.’ Well, a little bit of dust will be no obstacle, seeing as I intend to rip out its innards anyhow (carefully, of course) before reassembling it with a pinhole behind the shutter mechanism. 

The Clack is a simple 120 roll film box camera introduced by Agfa in 1954. It will produce eight 6x9cm images per roll of film and has a fixed shutter speed of 1/30s (plus bulb) and two aperture settings, for sunny or cloudy weather (approximately f16 and f11, respectively.) It also features a ‘close-up’ lens or a yellow filter depending on the model. The early models were made of metal and the later versions of moulded plastic.

Taking apart a Clack is the easiest camera conversion ever. First remove the silver ring by unscrewing the single screw underneath the lens turret. Then twist the cover and it should pop off, revealing the lens above the shutter and aperture mechanism. 

The lens is held in place with a couple of pins and a single screw. Undo this screw and lift off the lens. Below is the aperture and shutter fixed to a plastic plate with two screws. Undo these and prise off the plate. You won’t be able to lift it much, though, since the two wires that power the flash are soldered to contacts under the plate. These wires need to be cut to fully remove the plate. 

Underneath the plate is a hole which opens to the camera body. The pinhole needs to be fixed here. It is possible, apparently, to just place this centrally over the hole and screw the plate back in place, but my pinhole kept on moving and I ended up glueing it in place. Just make sure that the pinhole is centred in the hole. Once the pinhole is in place, the camera can be reassembled. 

And that’s it. Except that for me it wasn’t quite. Although the lens is normally removed, I read somewhere that replacing the lens can give a bit extra sharpness, so I thought I would give that a try. However, what I did was take the lens, remove it from the holder and then flip it. Hopefully, this will give a slightly sharper pinhole image with distortion around the edges: the Deakinizer effect.

The distance of the pinhole to the focal plane (the focal length) of the Clack is about 72mm, and the pinhole aperture was 0.3mm, so by dividing the the focal length by the diameter of the pinhole we get an f-number of f240. I’ll use this measurement to determine the exposure time depending on the speed (ISO) of the film that I’ll be using.

Hopefully I’ll be able to get the flipped lens pinhole Agfa Clack out before the current Shitty Camera Challenge ends in January, but I’ve got a fair few things to do before then.

I have to use my mechanical keyboard now.

My first year with the Frugal Film Project was a mixed bag. For a start it was really only ten months, we were away on holiday during August and apart from a few days in October when I took an Agfa Clack clone instead of the Clack that month was a washout. I also didn’t get out and about as much as I had intended and my outings weren’t as adventurous as I had hoped. I was also continually challenged with the Clack (or rather Clacks as they both had the same issue) by ‘fat’ rolls, where the film and backing paper did not wrap tightly around the take-up spool. 

Despite all of these challenges, it was an enjoyable year and I really got to love my Agfa Clacks by the end of the year I had two Clacks on the go: the conventional Agfa Clack and a second model that I cleaned up and flipped the single lens. This produced photographs with a lovely radial blur around the outside of the image. I also explored multiple exposures, trichromes, and even the Vortoscope, three mirrors clamped together in a triangle shape like an open-ended kaleidoscope. 

In Early December I took the flipped lens Agfa Clack with me to try some trichromes. Sadly,  by my own fault I completely underexposed the images, so right at the tail end of the month I tried again. I headed to Águas Boas and made trichromes of my favourite views, the bandstand in the park and a lonely tree that sits in a field raised above the road. I also grabbed shots of a Christmas decoration by the roadside and the window of a derelict house. The lab I use in Aveiro only has a mask for 6×7 sized frames, not 6×9, the format of the Agfa Clack. So I end up with some strangely frames trichromes from time to time. Yes, I can scan the images again with the DigitaLiza Max, but sometimes I really like how these oddly framed trichromes come out.

I already have my film/camera combination ready for next year’s Frugal Film Project, in fact by the time this post is published (or is it ‘dropped’ in the modern vernacular) I’m sure I will have already posted my first images. Looking forward to seeing you all in 2024.

After giving the Agfa Billy-Clack No.51 a good clean it was time to put it through its paces for the first time in who knows how long. From the state of the camera, with its dirty body and hazy glass, it was clearly a long time since it had been used but it was now clean and the shutter was firing nicely.

The Agfa Billy-Clack  has a single shutter speed of about 1/30s and three aperture settings (f8.8, f11 and f16), which are set with a lever on the front of the camera. In the late 1930s, when this camera was most likely made, the speed of typical films would have been about ISO 30-50. Modern films have a generous latitude and I reckoned that a fil with a speed of about ISO 100 would be perfectly usable in the camera.

For my first test with this camera I chose to use Lomochrome Purple from Lomography, a colour shifting film that turns vegetation to shades of red, as the infrared stock, Kodak Aerochrome, used to do. Lomochrome Purple has an ISO rating of 100-400, so it has quite a large latitude, but I still wondered if that might be too sensitive for the Billy-Clack. I therefore decided that I would set the aperture of the Billy-Clack to its smallest aperture (f16, it was a sunny day) and also used an ND2 filter, which would further cut exposure down by a stop.

To minimise camera shake, I rested the camera on a tripod each time I took a photograph. Thus of the 16 exposures on the roll I actually had 8 duplicated photographs, one without the filter and one with the ND filter.

On the back of the Bill-Clack is a long swivelling cover, behind which are two red windows to space sixteen 6×4,5 exposures from a normal 120 film. I thought that it might be quite complicated using the two windows, but in fact it was quite easy to keep track of the exposures.

On completing the film around the Melia Ria Hotel in the centre of Aveiro it was time to take it to Forever Blue for processing. Upon fully winding on the film and opening the back I found the film was tightly wound around the take up spool.  No worries about getting ‘fat’ rolls here. Now there was a nervous week waiting for the film to be developed and scanned.

Just after lunch today the smartphone chimed and there was a WeTransfer email in my in box. With some nervousness I opened and extracted the directories to find sixteen beautifully exposed images. I was thrilled. A quick check showed that thee were no obvious light leaks, although on one duplicate set there was a large red blob that might have been light getting in somewhere.

I really liked how these images came out. With most of them there was little difference between the frames taken with the ND filter and those without. In the exposures without the ND filter the grass was a little darker and in the frames with the ND filter the images were perhaps a little bit warmer, but there certainly wasn’t much difference between them. With my next experiment I think I’ll just use a film without any filters. In fact, I quite fancy trying out the Billy-Clack with some Lomography Redscale.

A traditional fishing boat filled with tourists floats along the canals of Aveiro, Portugal.

I’ve been good recently, really good, but then a long sought after camera appeared on the Kamerastore website. It was probably overpriced, and not in good condition according to the description, but I added a new Clack to my growing collection. This time an Agfa Billy-Clack.

The Agfa Billy Clack is a strut-folding camera made by Agfa from about 1934 to 1940. There were two models; the Billy-Clack No. 51, which takes sixteen 6×4,5cm photos on a roll of 120 film, and the Billy-Clack No.74, which takes eight 6×9 cm pictures on a roll of 120 film. Both models were nearly identical, the body of the Billy-Clack No. 51 was slightly smaller, featuring a single shutter speed of about 1/30s (and ‘B’) and three aperture settings (f8.8, f11 and f16), which are set with a lever on the front of the camera.

The model on the Kamerastore website was the Billy-Clack No. 51 and was described as having, ‘rust on the body. Fungus, haze, and dust inside the lens. A bit loose and worn throughout’. I felt this was going to be a long-term project, but when the Agfa Billy-Clack arrived, it was lovely. This is the later version with the vertical lines on the front leatherette, which suggest that it dates from 1938-40.

The condition of the Billy-Clack was better than I thought, though it certainly needed a good clean. The leatherette and the front plate was dirty, the front lens was full of haze, and inside the film chamber and rear lens was full of haze and dust. The ‘brilliant’ viewfinders on the front plate for landscape and portrait image orientation were anything but, they were filled with dust and haze. On the top of the Billy-Clack is a sports finder, that opens up and allows the user to frame an image without using the mirrored viewfinders. However, on mine this was broken, so I’m going to keep it closed.

I gave the Agfa Billy-Clack a good clean of the outside with a gentle wipe and on the inside with a cotton bud soaked in methanol. The cleaned the film chamber and the rear lens quite nicely. I lot of dirt and grime came out of the metal film holders and the places where the film and take-up spool sits and I reckon they had not been cleaned in a long time. On the front of the Billy-Clack I couldn’t get into the ‘guts’ of the camera because there was a rusty screw firmly stuck in the plate. I was able to clean the front glass and the viewfinders though, which now look really ‘brilliant’. There was one minor hiccup, for a few minutes I lost a tiny screw from the front plate.

One thing I did discover while cleaning the Billy-Clack is that the take-up mechanism isn’t compatible with some modern plastic spools, at least with my camera. Sometimes the spools are just too big for the metal guides, which have a little circle of metal that protrudes out and catches the smooth top of the plastic spool, making it stick. Looking at older spools, there is a little indentation in the flat circular part that fits snugly into the frame and allows the spool to turn smoothly. Fortunately I have a few older metal and wooden spools, and some plastic ones that work, but I’m going to have to be very careful with making sure that I get them back from the lab when processing.

On the back of the Bill-Clack is a long swivelling cover, behind which are two red windows. The Billy-Clack No. 74 only has one window, because it is a regular 120 film camera, but because the Agfa Billy-Clack No. 51 is a 6×4,5 frame camera it uses two windows to align the frames properly on the negative.to get 16 exposures from a normal 120 film. The film is wound on until a number appears in the first window, and an image is taken. The film is then advanced until the same number appears in the second window, when another image can be taken. Then the film is wound on until the next number appears in the first window for the next image until all 16 images have been taken. Of course, with a 120 film the frame numbers don’t go to 16 but to 8, because the windows are in the same position to read numbers for a camera taking 6x9cm images.

Now that the Bill-Clack has been cleaned it looks much better. The viewfinders really are brilliant now and the front glass and rear lens are clear of dirt and haze. I’m hoping that the lens inside the camera has also been protected, but unfortunately because of the stuck screw I could not get to it. Typically, film available at the time would have had an ISO of around 30-50, and according to what I have learned with a modern 100 ISO film I can use an aperture f16 for sunny conditions, f11 for hazy days and f8.8 for cloudy conditions. My first test will load a roll of Lomochrome Purple that I had sitting around for a while and will see how that works. But that will be a post for another day.

An Agfa Billy-Clack No. 51 strut fodling camera against a grey background.

After trying different films in the Agfa Clack, different cameras with Fomapan Retro, I was still getting ‘fat’ rolls in both Agfa Clacks, the original and the ‘flipped lens’ version. My last resort was to cut some pieces of sponge and put them inside the body of the camera. Glued underneath the film take-up spool, the idea was that the sponge would keep the roll tight enough that we won’t get ‘fat’ rolls any more.

There was no #FrugalFilmProject roll for October as since I had ventured with the Vredeborch Felica it had done little else but rain, rain, rain. However, the weather broke around tge beginning of November and I took the original Agfa Clack with sponge-modification and the Vortoscope to Aveiro. It was more a test of the sponge modification than a real entry for the Frugal Film Project, but I also wanted to try the Vortoscope and some multiple exposures. 

The results were spectacular. For the first time I had beautifully exposed frames, no light leaks and, best of all, a tightly wound roll of film. I was really happy with how the Vortoscope behaved as well, although it was difficult to properly frame it, the missed Melia Ria Hotel is a good example. 

I also tried a few multiple exposures, too, again with mixed success. That said, my aim was really to test whether I had beaten the ‘fat’ roll issue and it was certainly the most tightly wound roll I’ve seen for a long time. It was just the first roll, but all being well the issue is resolved. Huzzah!

I was really thrilled with the first roll of film put through the sponge-modified Agfa Clack. Vortograph of the railway lines in Oiã. #Vortoscope, #Agfa, #Clack, #AlvinLangdonCoburn, #AgfaClack, #Fomapan, #FrugalFilmProject,

Abstract photograph of railway lines. The image has been fractured caused by reflection of the image inside the Vortoscope, three mirrors clamped together in a triangular formation.

It’s been a funny old month, but today I managed to get out with the Agfa Clack and take some photos for June. This time it was just under the wire, but I had a plan to make some trichromes of the new street art that had been commissioned by the local council.

Unfortunately, the curse of the ‘fat rolls’ struck again. A ‘fat roll’ is where the paper and film doesn’t wrap tightly around the film take up spool. If you squeeze it then you can feel it is loose and the likelihood is that light will cause fogging on some of the images, especially near the end of the roll.

I’m beginning to think that the fat roll situation is not caused by the Clack, or by my general incompetence, but by a poorly rolled batched of Fomapan. What I will do at some stage is try a different kind of film in the camera, I think the Clack and Lomochrome Turquoise would get on very well, but in the meantime I will just have to put up with it.

So my plan to make a trichrome of the street art was a bit of a bust, which is a shame since in the morning light the rose is a lovely shade of red. I did take another trichrome of a long abandoned house (one of my favourite subjects in Oiã), which was much more successful. 

On the two remaining frames I experimented with multiple exposures, which was a complete failure and I haven’t bothered with that one, and the Vortoscope. If you are not familiar with the Vortoscope it’s like an open kaleidoscope; three mirrors fixed together in a triangle shape. Originally developed at the beginning of the 20th century, the Vortoscope shatters its subjects into a myriad pieces.

I chose a black and white garage door, that I also used with the Gameboy, and again the results were spectacular. One month I am certainly going to devote the whole roll to Vortoscope imagery.
