Worldwide Pinhole Photography Day 2013

On the 28th April 2013 it was Worldwide Pinhole Photography Day and I had been building a camera over the last three weeks to take part in it. As it turned out, I was quite busy on the actual day but managed to make a still life exposure with my creation as well as some self-portraits with the Holga 120WPC.

With my pending fatherhood, I decided that I would make a still life based on my wife and I's past, present and future. Fatherhood is something I'm looking forward to and marks a big change in our life together. The exposure took about an hour but I cut it short by 15 minutes as we were leaving to see friends.

Later that night I set up my trays in the bathroom and developed the paper. It was looking great but had a slight mottling effect across the image. I mulled it over for more that a week as to what this could be with the prime suspect being the filter I was using. What didn't make sense was that the image was fine - distortions in the filter would cause the image to be distorted too and I couldn't see any in the still life. A couple of people suggested the paper and that is when it hit me - during the developing stage I had forgotten to click the bathroom door shut. This usually isn't a problem as our hallway is quite dark but on this occasion my cat had decided to see what I was doing in there and pushed the door open to stick his head is. Bingo!

Earlier in the morning I made a few exposures with the Holga 120WPC pinhole camera to make sure I had something with mark the day. It was a lot of fun. I played primarily with double exposures and movement within single exposures but, again, my cat was making this difficult as he walked around my statue pose so here are the best.

This roll of film represents the last of my Fomapan stock. Fomapan is a cheaper brand of film from the Czech Republic and is really good for playing around with. It's major downside is how easy it is to scratch. As sheet film I can imagine it is far more forgiving as the film is not moving but pulling a roll through cameras like the Holga is something it doesn't handle well. The entire roll from this session was scratched badly from a small imperfection in the moulded plastic. For that reason, as well as others, I am glad to see the back of it and would only consider it again when I dabble in large format photography. I'm an Ilford man at heart and will be returning to them with my next bulk buy.

Project Pinhole: The Camera

In the last couple of posts I have been talking about the large format pinhole camera that I am building. I started with the film holder made from thick card which was looking good and only needs a couple of tweaks to get it perfect for it's use. The decision had been made to make the first incarnation of the camera out of card too so I got started.

I divided the build into three parts - the rear standard, the bellows, and the front standard. In large format camera terms, this refers to the rear section that houses the film holder and viewing glass, and the front section that houses the lens. Between the two of them you have the bellows bridging the gap. That is a very simple way to look at it - the sections do more than that but those are the basics you need to know.

With a pinhole camera, things are even simpler. There is no viewing glass so you only need to house the film holder and there is technically no lens either.

The structure of the camera would be built from thick cardboard and I would then cover all the visible surfaces in nice white card that would help with the rigidity but also make it prettier.

The Rear Standard

I started by building a tray that the film holder would slot into from one side. I left plenty of room for it to slide in and out of as the plan was to have a second piece of card slide in behind the film holder once it was in place and pin it to the top of the opening. That along with a soft light seal along that edge would make the opening light tight. This method would give the cardboard structure of the camera an easier time - creating an opening that was perfect in size would eventually weaken the film holder and camera, and would be at risk of falling out when being moved.

The Bellows

Pinhole cameras don't need bellows for focusing as everything from right in front of the camera to infinity is in focus. This meant I could just build out the camera to the focal length I had decided on and leave it there. That said, I had originally designed it to have a tapering effect from the rear to the front. It's an effect that would have been quite obvious in thicker wood but not to much with the thinner card. It looks good though and I'm glad I stuck with it.

The distance between the front and the rear plays a big part in what the final images will look like. Close together and the image will be very very wide. Further apart and the image will be zoomed in. I'm a big fan of my 50mm lens on my SLRs so I wanted this camera to have the equivilant size - that was 300mm. Once I started building I saw some images of shorter focal lengths and changed it to 240mm and then again to 210mm which I've stuck with.

The Front Standard

The front standard needed to do two things - house the pinhole and also a shutter. The design for this is very similar to the Holga 120WPC that I have - a shutter that slides back and forth in front of the pinhole. To do this I made two square pieces of card, one bigger that the other, stacked on the front. The lower square had the middle cut out of it horizontally to allow another longer piece of card to take it's place. When I say longer, I mean long enough to span the width of the camera and then some. This would let me press in either side to open and close the shutter. I cut a square into the shutter to allow an open state when pressed in from one direction.

The Pinhole

The size of the pinhole is determined by the focal length. There is a website that is superb for determining the size you need by the focal length you've decided on and vise versa called Mr Pinhole. By entering the focal length it will give you the diameter of the pinhole you need. It also gives you the f/stop that will help to meter your compositions.

For a focal length of 204mm I needed a diameter of 0.6mm. The first needle I found in the house gave me a diameter of 0.588mm which was close enough for me. At this diameter I would have an f/stop of 347. This is a very high f/stop and would result is extremely long exposures - in my first meter reading on a bright sunny day I was told 2mins 30secs. Inside in a bright room it would take 45mins to 1hr.

Because I would mainly be using photo paper with this camera, I needed to cut down the contrast that happens when doing this. There are a number of ways of doing this - pre-flashing the paper can do it of some kind of filter. I opted for the filter method and taped my 00 multigrade filter from my darkroom enlarger to the rear of the frot standard. I use this filter in the darkroom for exactly the same reason as I needed it now - to give an even exposure with normal contrast.

The Finished Result

Test Shots

I took two tests when I'd finished the camera. The first one from our balcony which I didn't expose for long enough. The second was towards our local football team's stadium when there was a match on. This was was far better.

Overall the result was good. There is a slight light leak from the film holder which I expected but nothing like what I thought it was going to be. It's an easy fix.

I've really enjoyed myself with this project and I'm looking forward to tweaking the design and taking it out into the field. I'll keep you posted.

Pinhole Obsession

When I look back through my folders of negatives, I notice that I have spent a lot of time on pinhole photography. In 2011 I built a matchbox pinhole camera in time for Worldwide Pinhole Photography Day which structurally was great but my exposure times were all over the place - I was baking the film with light. In 2012 I was given a Holga 120WPC which has been a fantastic camera to use and I have made a some of my favourite photographs with it. The obsession has moved on a bit though and I've had an idea.

The Holga 120WPC was a very cheap camera compared to it's competition - the Zero Image cameras are made from fine wood and brass fixtures but Holga did what they do best using plastic and simple moulds to keep the cost down. To me, it's important not to get carried away with pinhole cameras - they are boxes with a pinhole in one side that hold a medium for recording the image on the other side and no matter what you spend this will never change. The Holga is perfect for that.

At this year's Alt Photo festival opening night I captured the bustling room over eight full minutes. James Pearson who was also at the event said that he would stand still for the entire time so that one lone person would appear in the image. This is where I admit that I led James down the garden path because I miscalculated it by one stop of light. James believed it would take a long but managable four minutes but I had to inform him halfway in that it was actually going to take eight. An absolutely trooper though, he stayed for the additional four minutes and I was very pleased with the result.

Whilst we were at the opening evening James and I were given the opportunity to have a good look at the Harman 8x10" before it was officially launched at Focus on Imaging in Birmingham. This camera is simply a larger version of the 4x5" that launched in 2011. I have wanted the 4x5" version since it's release but, bearing in mind what I said earlier, £165 is a lot of money. Seeing the 8x10" version filled my heart with want again though, but I already knew that the target price for this camera was going to be a little under £300. I was out. The £300 (as with the cost of the 4x5" version) doesn't include a film holder which are a pretty penny themselves. I was definitely out.

Seeing this camera gave me an idea though - if I firmly believe that these cameras are just boxes with holes then why can't I build one? I've researched heavily into this and I have an idea of what I want from this project and have started to draw out plans. Worldwide Pinhole Photography Day is next month and would be an ideal time to have it ready for, but I'm not going to rush it for the sake of that - I want this to be well thought out, cheap, and most importantly...work. I'll keep you all updated on my progress once I make a start. Stay tuned.

Abandoned Televisions

Abandoned TVs started as a bit of fun on Instagram but has become an obsession for my walk to and from work. Rarely a week passes where I don't spot a TV at the roadside or beside a bin so I thought I'd share some of my favourites and talk a little about where I see the project going.

The first photo I ever posted of an abandoned TV is above but it actually started before that when I spotted a TV sitting on a table with a lamp beside it at the roadside. I became interested in the idea of urban still lifes like this - objects gathered together (usually on bin collection day) at the side of the road outside of their usual surroundings - but what I actually started to notice were more and more TVs of different ages and styles.

As I said, it was a bit of fun - I started off spotting two or three a week and posting my favourites on Instagram but I have never stopped seeing them and it is fast approaching a year since I started. I don't post them all as some of them are just not interesting but I've included some of my favourites of what I do post below.

As the project has grown I've made plans to move it into my film work - specifically my Holga as it matches how much I enjoy shooting with the Hipstamatic app on the iPhone. I've taken a few on my 35mm camera  as well which I enjoyed as it allowed me to play with depth of field but there aren't many at this stage.

There is part of me that really likes having this on Instagram though so it will remain there for the time being, but to have this join my film work would probably please me more and I hope to have that happen in the future. Until then, if you're not following me on there already and would like to see more of this random project of mine then please feel free to add me (my username is "iainkendall") and let me know what you think.
