How things change

August 13th, 2010 Jonathan No comments

Recently, I would say that photography is my favourite hobby. But it wasn’t always that way.

Throughout my childhood, I’ve taken pictures of important occasions on single-use cameras. My parents would always buy me a single-use camera before a family holiday, for example. I wasn’t interested in the camera, though.

A few years ago (2005, I think) I lived in hall of residence with a guy who had a “fancy camera”. I was so uninterested in it that I have no idea what it actually was. It was digital, and it had a big lens on it. This just goes to show that I didn’t care about photography at the time.

More recently, in 2007, I had a Sony Ericsson K800i camera phone. For a phone, it had an extremely decent camera and could compete with some of the entry-level digital compacts available at the time. But I still only really used it for taking photos of things that were happening around me.

But then, my colleague Paul starting doing his photo-a-day in 2008. I became a keen follower of his photo blog, and started to take “arty” shots on my phone. I enjoyed it so much that I quickly ran into the limitations of my phone and started wondering about buying a “real” camera.

There was a decent superzoom “bridge” camera in the office so I borrowed this for a few days and had great fun with it. Then unfortunately I was involved in an accident and dislocated my shoulder. Stuck at home, bored, I bought a camera. It was a bridge camera, one mark up on the one I’d borrowed from work. I bought it primarily as a high-tech toy, and with not much interest in the art of photography.

This was the stimulus I needed, and with a powerful and versatile camera I tried all sorts of photography. Gradually I became interested in the art of taking photos, and I now try to take photos that are nice to look at, as well as fun to take.

In 2009, I was given an unwanted 35mm SLR. At first I was sceptical – how useful could film be? I bought some film and had a go. I really enjoyed using an SLR for the first time and immediately wanted a DSLR.

In 2010, I caved in and bought a DSLR. I also continued shooting film and I now have a collection of around ten cameras – all film except for the DSLR. I’m still more interested in the cameras and the techniques in using them, but I hope that my work is also pleasing to look at. Make up your own mind.

Flashbulbs

August 5th, 2010 Jonathan No comments

A while back, I bought a Conway Synchronised box camera which came with a Coro Flash included. More recently I managed to get hold of some flash bulbs for it, but had trouble using them.

Using a multimeter and some paperclips I tested each stage of the flashgun and the synchronised trigger mechanism in the camera and found that each stage of the system worked in isolation, but still no joy taking photographs with a flash. I think some of the connections were a bit loose due to corrosion.

I took the (very simple) flashgun apart and washed all of its copper connectors in spirit vinegar to make them red and shiny again. Most importantly, I found it was necessary to scratch the corrosion off the contacts of each bulb before use, using the handle of a teaspoon or similar.

Now I can enjoy reasonably reliable retro flash photography, using Philips Photoflux PF1b flashbulbs. They’re quite expensive but I bought 15 bulbs from eBay for about a tenner. They’re good fun to simulate “proper” retro photography.

A note to anyone who is old enough to remember this stuff from first time round: Sorry for being so excited about obsolete technology. I’m just discovering this stuff for myself and I think it’s great! :D

User manual for the Kodak Six-20 Brownie

June 26th, 2010 Jonathan No comments

This week I borrowed a Kodak Six-20 Brownie from Hana’s dad. It’s the least I can do to quickly scan the user manual in in case it’s useful to someone.

New camera: Lomo Lubitel 166

June 26th, 2010 Jonathan No comments

I’ve been on a bit of a rampage with vintage cameras lately. Not content with three “boring” Canon 35mm SLRs, I recently acquired a late 1950s Paxette point’n'shoot and a mid 1950s Conway box camera.

The Conway was my first foray into the world of medium format, and I like it. Only days after developing the first couple of rolls of film from it, my Hana’s dad lent me a 1934 Kodak Six-20 Brownie. This takes a slightly different format film: 620 instead of 120 (but that’s a different story).

But I digress. Today Hana and I went to a car boot sale, and I spotted a LOMO Lubitel 166.  (cyrillic: ЛОМО Любитель. Means amateur in Russian). I’ve been looking at the Lubitel range and other inexpensive TLRs on eBay for some time, so I snapped it up. Yay for my sixth camera.

It’s in extremely good condition, albeit without the neck strap, lens cap or any other accessories. The glass is scratch-free and shows no signs of fungus. All of the mechanisms appear to work correctly, apart from the self-timer (which counts down, but fails to fire the shutter).

There’s not really much more I can add at this stage, except to say that I plan to get film in it as soon as possible, and the results will be on my photo blog when I’ve found a better method of digitising 120-format negatives than the one I used here..

Converting 120 film to 620

June 26th, 2010 Jonathan No comments

Recently I was lent a Kodak Six-20 Brownie box camera. Rather than the 120 medium format film I’ve used in the past, it takes 620 film.

The film stock is identical; only the spools differ. The 620 spool has a thinner axle, the end caps have a smaller diameter by about 2mm, and  the overall length of the entire spool is about 2mm shorter.

Original 120, 620 and modern 120 film spools with modern 120 film

120 film is still readily available but 620 film is very hard to find. There are two options:

  • Buy some empty 620 spools, and respool the 120 film in a darkroom
  • Modify the 120 spool of each new film by filing it down

I find roll film quite frustrating to work with in a darkroom and I didn’t fancy respooling it unless there was no other choice. So I decided to have a go at butchering a roll of 120. Even if it went wrong, I’d only have ruined £4 of film.

With the film still on the roll as new, I filed down the fatness of the end caps and then filed down their diameter. Fortunately I had one empty 620 spool to use as a template for my hack. It took only about ten minutes, but obviously filing away plastic left a lot of dust, so I had to make sure the film was extremely clean before putting it in the camera. I brushed it, and sprayed it with a can of compressed air.

The film now fits nicely into the Brownie, and I look forward to shooting with it. :)

User manual for the Conway Synchronised box camera

June 23rd, 2010 Jonathan No comments

Whenever I buy old or hard-to-find things from the Internet I often like to look at the user manuals first. But it can often be hard to find them, and I’m grateful when other people take the time to scan or type out their product literature.

I recently bought a Conway box camera, dating back to the late 1950s. It came with a user manual, so it’s the least I can do to scan and reproduce it here. Hopefully it will be useful to somebody.

I’ve also linked the manual on camerapedia.org – a great resource for finding out about vintage cameras.

New camera: Coronet Conway Synchronised

June 18th, 2010 Jonathan No comments

For some time now I’ve been wanting to get into medium format photography. I have the right developing stuff to process the films myself, but unfortunately no way of scanning the negatives without buying a flat-bed scanner. But my colleague Paul offered to scan 120 roll film if I processed it first. With this barrier removed, I decided to give it a go.

Many of the readily-available 120-format cameras are so-called “toy cameras” such as the Holga and Diana. I wasn’t interested in modern(ish) toy cameras, and instead looked for anything old and inexpensive.

Eventually I bought a Coronet Conway Synchronised: a cheap 1950s box camera, made in Birmingham. I was drawn to it because it came in its original box with manual, paperwork, and a parabolic flashgun.

Coronet Conway Synchronised

It’s extremely crude, with a fixed aperture and fixed shutter speed at approximately 1/30s (or bulb mode). The lens is fixed-focus from 9 feet to infinity, with a small lever to snap it into “close up” mode – 4 to 9 feet.

What this means is there’s no metering or manual control of any sort. The only control I have over exposure is the choice of film speed. There’s no guidance in the user manual on which film speed to use, so I’ve gone with a fast film – some Ilford HP5+ 400.

I mentioned this camera came with a flashgun, the Coro Flash. It takes bayonet-type single-use flash bulbs like the PF3N. These are almost impossible to come by these days, but fortunately I found that the PF1 with an adapter will fit. PF1 bulbs are somewhat easier to find on eBay, so I’ve ordered a box of 15 and will try my hand at dangerous indoor photography :)

I shot a roll of any old rubbish, just to test the camera and see if the film was a good match. Turns out the exposure was almost spot-on every time, in a variety of lighting situations, so I’m very pleased. Unfortunately, in my confusion in loading the film I didn’t line up the right set of numbers with the little window on the back of the camera.

The camera is supposed to be wound on 9cm after each photo: by following the numbers, I was winding it on 6cm. The photos are all overlapping. But it has probably worked out for the best. I’ve ended up with a long, blended patchwork panorama of what was otherwise a set of garbage test shots.

Like I said, I don’t have any way of scanning these photos and I’m not about to ask Paul to waste his  time scanning the results of my partially failed experiment. I found a sort of workaround, by attaching the film to my computer screens, bringing up a white page, taking photos on my DSLR, and stitching them together with Hugin. The photos and the stitching are pretty bad, but you get the idea.

How to scan 120 roll film

You can click this preview for a bigger version. As far as I can make out, from left to right, you can see:

  • Two waterfalls in Brandon Hill park
  • Two shots of Cabot Tower, also in Brandon Hill park
  • My friend Nathan on a bench
  • Cabot Tower again
  • Nathan again
  • A leafy landscape
  • A shot over University Hall at Stoke Bishop (with the frames of my screens through it)
  • A long-shutter picture of a car driving past my balcony at night
  • My friends around my table
  • A car in the car park
  • Hana in the car park
  • Two views from my balcony – one portrait, and one landscape

As you can see, it’s a “disaster” in terms of producing good photos, but I rather like the effect of a mixture of memories from throughout the week. The frames of my monitors doesn’t help, but I might give this technique another go, using my TV screen :D

More on infrared

June 17th, 2010 Jonathan 2 comments

A while ago I shot some pseudo-infrared film: Ilford SFX 200. Unfortunately, being the impatient 6 year old that I really am, I didn’t fully read the data sheet.

The film is only sensitive up to 740 nm on a good day, while my filter only allows through wavelengths greater than 720 nm. Therefore, the film was almost guaranteed to be blank as hardly any light would get through.

Armed with this knowledge, I bought two rolls of Maco 820c which, as its name suggests, is sensitive up to 820 nm.

I also read a bit about how to meter properly when using an infrared filter. I set the ISO to 12 (the lowest my AE-1 will go). I attempted most of the photos 2 or 3 times, sometimes using the camera’s TTL meter with the filter on, and sometimes metering without the filter, then adding the filter and adding anywhere between 4 and 8 stops of exposure. In most cases the TTL light meter seemed to suggest about +7 stops, so I figured I was doing it about right.

I developed the film a couple of nights ago, and was disappointed to find it totally blank except for the one frame I’d shot without the filter. I hung it up to dry anyway, but then noticed that some ghostly images were appearing! I guess this means that I didn’t fix the film properly. Nonetheless, about half a dozen of the frames are showing underexposed images – which is progress. After about ten minutes the images stopped darkening so I moved them to a dimly-lit room to dry. I scanned them as quickly as possible, in case they disappeared again.

The negatives are massively underexposed, but the scanner was able to help a bit and I also used GIMP to boost the contrast massively. They look pretty awful and the grain is very coarse, but you can make out what the pictures are supposed to be if you look carefully. You can also see that much of the foliage is white, so I guess it worked :)

Some of the pictures also have fingerprints or creases, where the film got jammed while I loaded it onto my developing reel. It buckled and pinged out, and I had to poke it back in.

Here are some samples (published on this, my geek blog, rather than my photo blog, since I reserve the photo blog for pictures I actually like; and I consider these photos very much a scientific experiment!)

Royal Fort House

Centenary Sculpture, Royal Fort Garden

Nathan in Royal Fort Garden

Incidentally, it’s now been a couple of days since I developed the film, and the images are showing no signs of fading further. Goodness knows what caused the magic appearing effect, then.

I still have one roll of Maco 820c remaining. Next time I will increase exposure by many, many stops. 15, perhaps. The camera’s longest shutter speed is 2″ so this will almost certainly put me in the region of bulb exposures and stopwatches.

If this doesn’t yield decent results I’ll stop buying infrared film, because it’s not cheap!

Calibrating the focus ring on a Paxette

June 11th, 2010 Jonathan No comments

Recently I was given a Braun Paxette. After running a couple of rolls of film through it, I’ve decided that the focus isn’t quite calibrated correctly according to the focus ring.

Fortunately, you can loosen three grub screws around the snout of the lens and rotate the focus ring without moving the lens, line it up properly, and tighten it up again.

To calibrate the focus, you will need:

  • a bright and high-contrast object a known distance from the camera
  • some tracing paper or other diffuse translucent material

And here’s how we do it.

  1. Set up the camera on a tripod with the back open/removed. Attach the tracing paper where the film would usually go, like so:

    Calibrating a Paxette

  2. Put your bright object a known distance from the camera, and measure it. Call this distance X. If working indoors, try using something like a desk lamp or a TV screen (both are bright, with strong edges). If working outdoors, you could use a building with strong features (and pace out the distance from your camera).
  3. You might need to cast a shadow over the paper to see your image, but it should be there, albeit upside down.
  4. Focus the image so it is sharp. It can be hard to tell if the image is sharp, so you could use a magnifying glass to inspect it.
  5. When you’re happy that the image is in focus, you know that whatever your focus is set to now is X. Loosen the focus ring, readjust to that value, and tighten.

You’re done! Happy shooting.

Sunny 16

June 3rd, 2010 Jonathan No comments

Since using my Braun Paxette, I’ve had to learn about the Sunny 16 rule to get the exposure right. The details on this page are shamelessly stolen from Wikipedia.

The rule is simple.

  • Set your shutter speed to the inverse of your film speed.
ISO Shutter
100 1/100 (or 1/125)
200 1/200 (or 1/250)
400 1/400 (or 1/500)
  • Pick your aperture according to these conditions.
Aperture Lighting Conditions Shadow Detail
f/22 Snow/Sand Dark with sharp edges
f/16 Sunny Distinct
f/11 Slight Overcast Soft around edges
f/8 Overcast Barely visible
f/5.6 Heavy Overcast No shadows
f/4 Open Shade/Sunset No shadows

I’ve shot a couple of rolls of film in the Paxette now, with good success when it comes to exposure. Unfortunately the Paxette has a fixed shutter speed of 1/40 so it’s more a case of choosing the ISO to match the shutter. Fortunately Ilford produce a film with ISO50.

For a laugh, I also spent a day practising with my DSLR in full manual, exposing with the Sunny 16 rule. It worked!

I think all photographers should be aware of it, because it’s extremely useful. Give it a go!
