20 x 24 photographic paper out of date challenge

I have been having a clear out in the darkroom. More like seeing what printing paper I have in stock and how close to date they were getting. While checking I came across a pack of Ilford multigrade 4 peal RC 20 x 24 to large to miss but I have managed not to notice it for a long time.

It has been over looked all this time partly because it is pearl paper and that I am unable to use paper this size. I know why, then why have you not cut it down to size? Without trying to make excuses it is difficult to cut any size papers when you only have enough space on the dry side of the darkroom for your enlarger and I did not want to waste it if I could help it. A sort of unintended waiting game for the right project only I did not think it would take about 15 years.


A few days ago I was setting up the enlarger to make some 9.5 x 12 prints from Kentmere 100 35mm film. That had some images of poppies made in the garden. All though they all turned out well. I had noticed, I was loosing about an inch or so off the side of the negative.

I started to speculate wouldn't it be nice to include that missing edge at the same ratio of enlargement without having to down size it to make it fit. This idea was going to be difficult to fulfill as my main sizes are 8 x 10 and 9.5 x 12. This left the 20 x 24 this maybe it's finest hour. 

After a certain point in time old paper starts to increase their latency. This means you need to start adding more exposure time (light ) to the paper to receive the same results you would get with the fresh stuff.

With paper this old you may as well chuck it in the bin. Yes! it is coming, if it was this article would be at an end. But! while I am processing anyway I may as well see if I can get any sort of image.


Where to start? a Segmented test print. Where you increase the amount of exposure at set times. The problem with this is you have no idea how many increments of light will be needed to arrive at the exposure. I short cut it by using the exposure time from the negative already set up using that exposure time as a starting point.

Fortunately the developer was fresh in that it had only half a dozen prints through it. To allow for the sluggish latency I would develop the print for two minutes. Twice normal for RC papers to give it a chance to produce tones.

Before we go any further we need to look at the negative I was using. It had been exposed to Foma 311 RC paper. It took 27 seconds at grade 3 with the lens set to F5.6. This would be the starting point then with one change the enlarger had to have the filter setting changed for multigrade 4.

After a little bit of contortionist cutting, the paper was in two bits of equal size well almost and the easel adjusted to allow for the new size, the paper was exposed. 

Surprisingly when I remove the paper from the processor after 2 mins there was a soft image, emboldened I increased the exposure to 30 secs. A slight increase but not enough. Time to get radical and doubled the light by opening the enlarging lens to F4.

The print was darker again but not enough to get a good black, so I opened the lens to f 2.8 at 30 secs. Effectively four time the light from when I started. When the print came off of the processor this time it was nearly perfect. I did another print adding 15 sec burn to the highlighted poppy. Done.

I did consider pre-flashing the paper this is where you add light to the point just before recording a tone to overcome the latency. I explain how it is done in a previous article link at the bottom of the page. You will properly have to make time changes from part seconds to seconds in the case of old papers. A case of testing to see what works to get the right result. There is also double grade printing a link at the bottom of the page explains this method as well.

A note of caution what works well for one pack of paper may not for another keeping your grey matter on its toes. It will be the case that no matter what is done you will not get the result you are looking for it is at that point a decision needs to be made to bin it.

I am pleased that I had a go with this paper. It has introduced me to a new format size for 35mm printing. I feel it is more pleasurable to look at with that bit of extra width. A sort of shortened panoramic feel.

When the same image is compared with the Foma 311 version it has a slight warmth to it which could be down to its age, if anything this adds to it. Making the Foma composition a little clinical looking. It is a unintended consequence of mixing different papers and throws up a question about creative choice. Which I'm go to leave you with to ponder.


All the photographs were reproduced using a phone camera and edited in Photoshop.

The first four pictures were made using Ilford multigrade 4 pearl RC.

The fifth is on Foma 311 gloss RC.

The Camera from Dresden part one.

 

This camera was almost an impulse buy, when I saw it in the window of a camera shop at a giveaway price. However, I did not have the cash on me. As I carried on walking down the street I thought it would be snapped up by some lucky individual embarking on a film camera odyssey.


At the time, I did not realize it would be me six weeks later. On inspecting the MTL 3, the body was in mint condition - not a single mark on it that I could see. However it did have some issues, the most obvious one being that it had no lens, the light meter did not work and the foam on the film door had perished. Shouldn’t be too difficult to put right, I thought.


When I got the Praktica home, I tried to remove the battery cover, but it was locked solid. I did not have time to go any further with it at that point and thought that I could always use a hand held meter. With that, I put the camera in the cupboard. 


Some weeks later I found myself going to the camera cupboard and picking up the Praktica. I had it in mind to get to the bottom of the stuck battery cover. I found a set of micro screwdrivers and undid the four screws that held the base plate on. I had no idea what I would find once the cover was removed. Fortunately, there were no springs that pinged out across the room when the base plate was lifted. I picked the battery housing off the base of the camera, only to be presented with a leaking battery - mystery solved.

Removing the aluminium battery cover from the metal insert was going to be a challenge. The battery had leaked into the threads, sticking the two parts together like super glue would. I don’t know what I was thinking when I squirted freeing oil on the thread and left it to sink in. I tried and failed to shift it using a fifty pence piece and a large adjustable spanner. There was no other course of action left to me but the brutality of fire and heat in a blow torch. I wondered if just heat would work?

As I walked across the room to the log stove, it was like walking into the sun. I left the battery housing on top of the log stove for five minutes or so and returned to the tropical room suitably dressed in shorts and, with heat resistant gloves, picked the battery cover off the stove. I placed the housing in the spanner and used the fifty pence piece in the cover and applied increasing amounts of pressure. With the sweat running down my face, it gave all of a sudden flicking the coin out of my fingers across the room. After I found the coin I placed it back in the slot and undid it as normal.

One issue down, three to go. The hunt was on to find a lens, battery and foam. I had forgotten what a waste of time looking for stuff on the net is. Some hours later, I had found a lens and battery (the modern number for it is LR9XP625G - the last three numbers are the most important). From the same place, I bought a Sigma 80-200 zoom lens. Thanks go to Bristol Cameras for their prompt and friendly service. The lens when it arrived was brand new and was the same price as the camera body.

I tracked down the foam to eBay and what a pain the seller was, to put it mildly. In the end I went down to a craft shop and picked up a sheet of foam for a pound - four times cheaper than the eBay seller!

With the light meter now working, the lens attached and the foam in place, it was time to load the camera with some film. I had an out of date roll of Fomapan 200, which is of a similar age to the camera, so that would do nicely.

Let the escapade begin.......It took a bit of time to get the film to wind on properly as I could now work out how the film lead picked up the wind on the cylinder. The sound and vibration from firing the shutter almost shocked it out of my hands. Must remember to grip it more firmly and use ear defenders.

To be fair, I had forgotten how basic the manufacture of this camera is and the sound of the shutter is quite reassuring. I don’t think I will be using it for candid street shots, but then again... It will take me a little time to get used to the way the camera is set up. It is a little chunky when making adjustments, but I will not let that put me off.
