DIY Cardboard Camera Mk2

After some success with the first cardboard box camera, and wanting to produce some large format (10×8 inch) images, I set about designing and building a new camera which could focus the image without being moved. This has the great advantage of being able to adjust the size an object appears in the image and still be in focus.

To achieve the variable focus I produced a box in two parts so that one slid inside the the other and joined them together, in a light-tight fashion, with a piece of black polythene bin liner. This give a light-tight but flexible join. I used the same film holder from the first camera with some improvements to make it more light tight. I added a channel to the new camera within which the film carrier could slide, using a strip of black paper to provide a flexible, light tight seal between the carrier and the box camera. The carrier is inserted in the top of the box.

As usual here, I am using Ilford glossy photo paper – at ISO6 and pre-flashing it to decrease contrast.

Utilising a spare vintage lens I ran a few test strips because even though the lens has marked F-stops, the distance between the lens and the film also affects light intensity. After running the tests I made the first 10×8 image (F22 2s exposure). This was in intense bright sunlight – not the best for a good tonal range – but it did really test the light-tightness of the camera. Here is an iphone shot of the negative a digitally produced invert to create the positive image. Once the negative is dry, I’ll take a high resolution photograph of it.

This works! – I am getting the tonal range and soft-dreamy look I am after – for a lot less money than the £800 10×8 antique camera on Ebay I’ve been considering.

Next step is to wait for a softer light and make some more images.

DIY Cardboard Large Format Camera

It was a very wet Monday morning – too wet to go out with the camera, so I thought I’d have a go at making my own large format camera to take 10×8 negatives. I have been looking to upgrade my 7×5 half plate bellows camera and so this would be an interesting step along the way. Using a spare lens that came with the bellows camera I bought last year I decided to make a fixed focus camera to do some close-up still life images. The lens  seems to have a 9 to 10 inch focus length and stops from 8 to 64.

The biggest challenge was making a dark slide to hold the negative (Ilford photographic paper – running at ISO 6). But eventually I have a design that is pretty light tight – but benefits from having the focussing cloth draped over it  when in use.

I used a “documents” box as my starting point, cutting a hole for the screen and dark slide. The screen is made from translucent stage lighting paper I had – but tracing paper would be as good.

Then a hole for the lens which was already mounted on a board, so some double sided tape fixed that to the box.

My first image was fogged and it was soon clear that the inside of the box needed blackening and the tiny holes at the corners and where the tabs fold in to make the lid all needed sealing up with black tape.

Once that was done – I made my first successful image. I have used it today with some more successful images – loving the image quality from the lens.

My still life work I have discovered is similar to that produced by the Czech photographer Josef Sudek who explored the play of light on ordinary objects and through his studio window in different weather conditions.

 

 

Adding a new camera to the collection

Two recent books have stirred my interest in exploring the variety of affordable vintage cameras that can still be used. The books are:
– Retro Cameras: The Collector’s Guide to Vintage Film Photography by John Wade.
  – Discovering Old Cameras, 1839-1939 by Robert White

This then led to exploring some of the discussion forums dedicated to vintage cameras – some just dedicated to a single manufacturer.

One helpful website was Emulsive on here is a comparison of three foldable cameras – one of which I have now bought – the German made – Agfa Record III.

For under £100 on Ebay this came with its leather case, a flashgun, yellow filter and lens hood.
Listed as “all appears to be working, but not tested with film”. When it arrived, the focus ring was seized, but with some patience a lot of force and the nearest dribble of WD40 it has freed up nicely.

This is a landscape format camera – taking a negative that is 9x6cm. This can be done with a 120 roll film – yielding 8 frames. However, I have a lot of pieces of X-ray film which I have now cut to 9x6cm. So my first test involved putting a single piece of film in the camera and closing the back.

Using the App “Light Meter” on my phone I measured for exposure using 100ISO for the blue x-ray film and took a few sample shots of the garden. As can be seen from the example below (photo of negative projected by enlarger and inverted to become positive, focus and exposure are good, but there is a flash of brightness – probably from a pinhole in the bellows. I put an LED light inside the bellows in a dark room and soon found 3 small holes. These will be dealt with – using flexible adhesive mixed with black pigment. – that’ll be in the next blog……

Refurbishing Antique Bellows Cameras

The Blog writing has been on the back burner whilst I spent time refurbishing my two 1900s, mahogany and brass bellows camera.

The Boots camera is a single-rack camera and less useful so I decided to refurbish this one keeping it as original as possible. The Hora camera is slightly more modern by 10 -20 years and has a double rack and pinion adjustment making it much more useable since focussing can be accomplished without changing the distance between the lens and the object. This Hora camera then was to be refurbished to make it as useable as possible.

Each camera was stripped down, as far as possible, to its component parts. IMG_3023  The wood was cleaned with “Soft Finish” remover to gently lift off grime leaving the patina intact. The wood was finished with liquid wax. All sliding surfaces had a light dressing of graphite powder to ease movement.

The brass was in a badly corroded state in many places.

The worst was treated to a light sanding with 600 wet&dry then polished with a cream cleaner. After completing the first camera my fingers hurt so I purchased a battery powered Dremel to do the buffing. However this new Dremel was dreadfully underpowered and stalled with the lightest pressure at the slow and medium speeds. After finishing the cleaning using the high speed only I returned the Dremel to Amazon who refunded me fully.

As the pictures show the bellows of the newer, Hora camera have had a lot of bookbinding tape applied to cover light leaks.

I bought, from a supplier in China, replacement bellows and glued them in place with flexible adhesive. Whilst the new bellows are fully light tight they are less stiff that the original and sag quite a bit. To address this I have attached a brass ring to the middle section of the bellows and use a tensioning wire to hold the bellows up. This is a period feature on some other cameras of this type.

The Boots camera had its glass screen cleaned with 1200 grit wet&dry carborundum paper. I still haven’t removed all the marks, but the glass is much clearer in use. It does still need new bellows but I want to locate a leather type to look more original than the Chinese polyester version.

Both cameras have now been completed.

because of the cleaning and lubricating graphite, are much easier to use. and I have taken some very pleasing images with them since the refurbishments, an example of which is below. More images to follow in my next blog.

North Somerset Artsweek 2019

It has been a very busy April/May – preparing 75 pieces for North Somerset Artsweek #nsaw2019 – but so worth it!

We have had a great response from visitors to the Clevedon Theatre Shop venue, in terms of numbers, purchases and (more importantly) conversations. Just today and tomorrow to go then time for a rest.

Antique camera at Hartland Quay

It has been a busy few weeks preparing for North Somerset ArtsWeek in May. I am exhibiting at The Theatre Shop, Clevedon BS21 6HX.

More of this later…..

Meanwhile I wanted to spend some time enjoying the drama that is the North Devon Coastline. No better place than Hartland Quay – and so it proved.

A two night stay at The Hartland Quay Hotel (recommended) gave me the time to view the cliffs and sea in a variety of light and weather conditions.

A mix of paper negatives and x-ray film was used. The X-ray film exposure times have been tricky to work out – I am still experimenting. Anything from 1/125s (using the Thompson Pickard shutter) and 2 seconds have yielded images, but the longer times do seem over-exposed on  processing. I have some more work to do on the images and will post later.
