Cold tone paper by Ilford with a touch of blue tone developer


When I order new materials for the darkroom I always add something I have not tried before. It can be anything but this time it just so happens it was a box of Ilfords new cooltone FB paper. I was interested to know what their definition of cool was. In my mind it means rich blacks and blueish tones in a very subtle way.



It has taken I bit of time to choose a set of negatives that would give this paper a good workout. Sometime ago I was fortunate to visit the thirty meter high Clydesdale horses heads known as the Kelpies at Falkirk. They are a wondrous sight to see glistening in the landscape. Even more so on the bright cloudless day I visited. Their stainless steel 'coats' sparkled in the sun as you walk round them, making it difficult to look at them without sun glasses. Trying to make photographs that are different is impossible as hundreds of people walk and stand around them taking pictures from every possible angle. It's a snappers paradise! But then every ones experience of these equine giants is different and so are the pictures made.


 
I used my Bronica 120 6x6 camera to make the pictures I had in mind. Which turned out to be about a dozen frames across two rolls of film. I am not prolific at the best of times but even I was surprised by how few images I had captured.

Armed with two pages of negatives I picked three frames to try this paper out on. I would start by developing the first picture in Ilfords own multigrade print developer this would be the standard to judge the others against. I will also be using my favourite cooltone developer as well.


It is not until you have the photograph in the day light that you can see what the tint of the paper is. It has a very bright white tint to the paper, making the blacks very crisp, but it still has a very subtle warmth to it when compared to Moersch 6 blue tone developer. I know I favour the cold working developer but I also like Ilford rendition of the horses nose, they each have there own character. 

Overall I am very pleased with the way the images have turned out. This paper appears to have a grade more contrast, I think this is due to the very white base colour of the paper compared to the neutral tone paper I am used to. It works well with my favourite blue tone developer. I will have to see if the blue is richer with this paper than others.

Preparing the Zero Pinhole Camera for use.


Using this camera is a real step back in time requiring you to put aside all those luxuries that the modern photographer has taken for granted. After all, it is just a box with a pinhole in it, the ultimate manual experience from loading the film and remembering to wind it on, to calculating the shutter speed.



Loading the film:

To start with you need to load a roll of film. That's obvious, most film cameras need film to work. If you are like me it has been a long time since you looked at the backing paper of a roll 120 film. I had forgotten that it is marked for the four different sizes in the 120 family and with the multi format camera it has three red coloured windows in which to view the film numbers. It also has a set of symbols that tell you when the number is about to appear in the window which also marks the middle of the frame. With this set up you cannot blame anyone else for winding it on to far, so it is a good idea to take it slow and gentle in the beginning. Before loading the film you need to set the format your going to use, once the back and top are in place, it is time to advance the film so the light-sensitive material is in front of the pinhole. When winding on you may notice that it becomes quite tight, this is where the celluloid attached to the backing paper is being drawn in front of the light box. Just continue gently on until the first frame number appears behind the little red window. Now the camera is primed for light capture.



Calculating exposure;

The Zero cameras aperture is set at F 235, it is important to remember this as this number is not written on the calculator attached to the back of the camera. The calculators outer ring shows shutter times from 8000 ths of a second too 15 hours, the inner ring shows F numbers from F 1.4 to F 500.


Please note that all the figures that follow are based on a film speed of 100 ISO.

Today, for example, my light meter is showing a light reading of F 5.6 @ 500 ths of a second. Now using the calculator move the dials so F5.6 is opposite 500 ths of a sec., then find F 235 on the outer ring and read off the time opposite which is about 3 second; you will need to make an adjustment for reciprocity effect by a factor of 2 making an exposure time of 6 seconds. I say 'about' because the next F number is 250 with an indicated shutter time of 4 seconds. To start with it is a bit hit and miss, that is why it is a good idea to make notes on shutter times so you can see where to make adjustments once the film has been developed.

You will need to make adjustments for the reciprocity effect as follows:

  • From 1 second and over compensate by multiplying by 2 giving an exposure of 2 seconds.
  • From 5 seconds and over compensate by multiplying by 5 giving an exposure of 25 seconds
  • From 50 seconds and over compensate by multiplying by 12 giving an exposure of 600 seconds/11 mins.

XP2 super meets Zero pinhole camera and then mugged by Kodak HC110

All of this film is beyond it's best
before date.

They say that fact is stranger than fiction - but this is not fiction! I have processed XP2 super 400 in Kodak's HC 110. It has produced some wonderfully smooth toned negatives with just the right amount of contrast. I really will not know how good these negatives are until they are darkroom printed.


This adventure started with my pinhole camera and the crazy idea that I would like to use the out of date XP2s sitting in my film cupboard. I have used this film in the past and been completely under whelmed by the flat looking photographs I received back from the lab. That is why I think I am being crazy!




So for the first time I am going to see what others have done and said about this film. I started with a bit of research something I do not usually do. When using a film product for the first time I like to approach it fresh without all the hurly burly from other people.


HC 110
Not to be mistake for golden syrup.
 
First I should explain that XP2 super is a chromogenic black and white film designed to be processed using the C41 process for colour film. Super is the updated version of the original XP2 first released in 1981.



With a quick search a number of references came up, the first one I went to was the online photographer blog. Written by Mike Johnston. I took two things away from this blog. First was how to get the best from the film in different light if you are using the C41 process. He suggests altering the ISO depending on the lighting conditions as the film can become very contrasty. Not from my experience.




  • For regular shooting in normal lighting ISO 200
  • For shooting in extremely bright and or contrasty light ISO 100
  • For shooting in low and low contrast lighting indoor or out ISO 400
  • He does not recommend using it at ISO 800

The other bit of information that took my eye but was not part of the post was about cross processing using the monochrome chemicals. This made me sit up and take note. I like the idea of using black and white material to process and print the film because I could do it in my darkroom without a costly upgrade.

I found the write up about using black and white chemistry on the Ilford photo web site. It is very informative and took some time to read. The author Chris Moss has not only developed XP2s in HC 110 but has also used Rodinal and Ilfotec HC. He has posted a lot of images to back all his work up.

HC 110 in syringes
It became apparent that he preferred HC 110 as most of the work described is devoted to this developer. It was at this point I decided to use HC 110 myself so I could in part test his results and cut out a lot of trial and error on my own account - a short cut so to speak. I was however disappointed to find that all his negatives had been scanned and not printed in the darkroom. The short cut in the beginning means I will have more time to experiment in the darkroom.

Lastly before I move onto my results it is worth mentioning Erik Gouldproject web site and in-particular his article on using HC 110 to control contrast by varying the dilution of the developer. This is mainly in response to Mike's assertion that XP2s can get very contrasty in certain situations. Most of this he relates to the C41 processed negatives he has produced. This could be the case for monochrome work.



Lets just check those setting again.
What have I gotten myself into! this was going to be a straight forward article about using XP2s and my pinhole camera. I'm pleased to say we are now getting on with the photography. The good thing about it is that I will be able to take part in world pinhole Day for the first time.

 I was able to go out over a number of days with my Zero that included world pinhole day to make the images. The sun was out which made a change from the dullness we had been experiencing, but it still had a bite.

I used three rolls of XP2s that I rated at 100 ISO I did this because it was a bright day and I wanted exposures that were seconds long rather than part seconds that a faster ISO would have produced. It also occurred to me after exposing a roll of delta 100 that I could do a comparison between the two films. In most cases it took about eight seconds for each exposure or round about as I can be quite cavalier when it comes to closing the shutter. This does lead to over exposing the film, something I should take in hand because I end up with longer printing times in the darkroom due to the density of the negatives.


XP2 S 400 negatives this shows
the colour of the neg base.

 It is the first time I have experienced scepticism and anticipation in relation to the results. A bit of an April fool feeling, no matter what happens I have a plan B or do I?


Right! I loaded the first roll into the tank. Developed it for 5 mins as suggested being a first for me, I develop one film at a time so I can adjust the dev time if needed. I used the HC 110 at a dilution of 1+49. Woe! this stuff is so concentrated it is like syrup. I was warned, which means using a normal graduated measure is out. You will need to use syringe/s to get the right amount of HC 110 out of the bottle if you are not going to end up with sticky fingers etc everywhere. They should be marked out in mls and part mls as the 49 works out at 12.3 mls in 600 mls of water. I wanted it to be the exact amount that was used.

Please note: that this article was written before Kodak changed the formulation of HC110 to make it easier to pour. This makes certain bit of this post superfluous but does not take away from the overall results. 


Contact print. 2 sec using white light.
When it came to processing the film I kept to my standard method 12 inversion for the first 30 seconds and then four inversion every minute there after. the stop was for two minutes with the same inversion count as the developer. I did the same for the fix, fixing for 5 mins and then checking to see if the film base had cleared. I did this partly because there can be an issue with under fixing if the fix is old which mine was having been used for five previous film. When I looked the base appeared a little foggy so I put it back in for a further two minutes.

While I was checking the film base I was relieved and pleased to see the tell tail squares that images were there. I now had the unspooled dripping wet film in my hand. To be presented with some wonderfully toned negatives on a pinkish magenta film base, was something I had not been prepared for. What wonders are to be had in the darkroom! Let the fun begin!? 

I recently exposed and developed some XP2s that is ten years out of best before date. There is an issue with fixing, you may find that after ten minutes of fixing that the base is still quite white looking  and has not cleared.  It is a normal situation that will clear once the film has been washed and dried.

FB papers developed in Tetenal new Eukobrom AC.

Four papers side by side.
There is not a great deal I can add to what I have already written about Eukobrom AC. I was not expecting to show you a set of FB prints so soon after my first use of this new developer. The questions I still have need a good amount of time to pass.


A partial answer to one question is that the developer will keep for at least three days after dilution. As long as it is bottled at the end of each session when being used in a tray. A litre of 1+9 strength so far has produced twenty images of mixed sizes. According to Tetenal you should get about 1,353 prints of 30 x 24 cm out of each 250 ml of concentrated developer. Which works out at about 54 prints per 100 ml diluted at 1+9. Obviously in practice this will vary depending on dilution, paper and conditions of use.

While I was developing the FB images I did notice that different    papers could take up to sixty seconds before they started to show any signs that the paper had been exposed and a further sixty to complete the process. Knowing when the increase in images appearance is down to reduced developer activity will take time to discover.



Ilford cooltone fibre base paper
I chose three makes of FB paper: Ilford cooltone, warmtone and natural - all gloss, Fomatone MG classic chamois 542 mat and Adox MCC gloss. All the papers were exposed at grade three but unlike their RC brothers the exposure time had to be adjusted as some of the papers required a lot less light. Again the tones had good separation, rich blacks and clear whites.




Of the three Ilford papers the natural paper took on a cool tone, where as the cooltone took on a warmish tone. This could be the first indication that the developer is depleting. If this is the case then it is exhibiting the same traits as those traditionally produced. The slight colour change indicating that the silver has not been fully developed. I have written about the changes of colour you can expect from exhausting developer in another article.
 
Fomaspeed 524 matt warmtone.


When it come to pushing or pulling the print (This is where you over expose the paper then pull it from the developer when it has reached full development before the suggested time for full development.) I have so far kept to standard use.

Tetenal Eukobrom AC first look

I like trying new things out in the darkroom, so when an offer to use Tetenal's new monochrome paper developer Eukobrom AC came up I jumped at it. I would like to thank Matt of AG Photographic and Tetenal for the chance to be one of the first to give it a test drive. A few weeks later a package arrived at the door, since then I have been chafing at the bit to try it out.

This is a new developer made for twenty first century. It is also the first commercially to use isoascorbate, vitamin C (you're not seeing things) as the main developing agent, it is a direct replacement for Hydroquinone the most widely used ingredient in photographic developers, noted for it's fast action and high contrast. It is marketed as the alternative to Ilfords multigrade all purpose paper developer producing the same sort of neutral tones. The developer works with both Fiber Baryta and resin coated light sensitive papers, whether multigrade or graded.

Diluted 1+9  Eukobrom

In to the Darkroom.

The first thing you notice with this developer is it's lack of odour. The next is the colour of the liquid, a rich yellow. I decided to dilute at 1+9. Once done I poured the contents of the measuring jug into a tray. I would have used my up right paper processor but that already had fresh Ilford multigrade in it. Using the tray for the new developer would allow me to note how long it took for the image to start appearing.

The comparison.

I have several makes of light sensitive paper in stock. I chose three, the most obvious Ilfords multigrade, Fomaspeed Variant 311 and Kentmere VC select gloss, all resin coated papers. I went to these first as they are reasonable quick to process and give an insight into how the Eukobrom will perform. Before moving on to FB papers. (results to follow in another post)

The set up.


I chose a negative from a recently developed set of Agfa APX100. I set the height of the enlarger so it would produce an enlargement of 9 x 12 then set the easel to 8x10. I did this because the Kentmere paper I wanted to include I only had in 9x12, this would keep everything consistent.

The test strip was processed in the multigrade developer and it was indicating that the image would need to be dodged, if I wanted a picture I was happy with. I set the enlarger as follows lens F8, grade 3, exposure: The whole image was exposed for twelve seconds, the sky from the bridge upwards plus eighteen seconds and finally the sky from half way up to the top of the image plus eighteen seconds. I would produce two pictures on each paper all at the same setting. The developers temperature was set at 20C.

 Paper developed in Multigrade
 
Results:

Both developers are advertised as neutral tone. To me this means they are subtlety on the cool side.

The differentiation started with:

  • The Ilford paper when compared with the other papers in the test, has a slight warmth to it's tone when developed in fresh multigrade. The Eukobrom is slightly cooler in look with a more intense black and crisper whites giving it a bit more contrast.
  • The Fomaspeed paper has a cooler look to it when developed in multigrade compared to the Ilford paper. The Eukobrom proved to be cooler looking again with more intense blacks and clearer whites again adding to the contrast.
  • The Kentmere paper is known to have a higher contrast level to the previous papers mentioned maybe as much as a grade. When developed in multigrade the image had a muddy look to it indicating over exposure with a slightly warm feel to it. The Eukobrom processed image had a cleaner crisper look. Again the midtones had better separation making it look more like a moon light picture instead of over exposed.

Once you understand that Eukobrom adds contrast to the image possibly more so than the Hydroquinone it replaces. It is easy to allow for by reducing the grade you would normally use. The blacks are wonderfully rich giving the pictures some real punch. The mid tones have more separation than Ilford multigrade but the surprise is the brightness of the whites.

Personally the main questions yet to be resolved are its keeping qualities and whether or not the image will be warm when the developer starts to deplete.

This is a nice developer to work with for prolonged periods as you do not get that developer smell lingering up your nose afterwards. Oh! It does look like OJ when diluted so keep it out of the reach of kids. It is a real gem and I will be ordering a bottle, it may even replace my favorite multigrade! Don't take my word for it try it for yourself you will not be disappointed.

A case of the wrong paper?

FG 1.  Ilford Multigrade RC developed in
Ilford multigrade developer


I was in the darkroom the other day doing some printing, when I noticed I had produced a print that did not match the test strip. This lead to a bit of head scratching. Then it occurred to me that the paper that was left from the last session in the test strip box was a different make. I had assumed it was Ilford, a logical thought, as it is the paper I use often.

I usually cut the paper I'm going to use into test strips at the beginning of each session. Only in this case I looked in the box and saw there were strips ready to go and just got on with printing. By strips I mean 8 x 10 paper cut in half.


FG 2.  Foma variant RC developed in
Multigrade 

I know that different makes of paper have different characteristics and levels of contrast. But I was not expecting such a big difference.

Lets set the scene: the negative is a 120 format Fomapan ISO 100. I had set the enlarger to F 11 and grade 2.5 - a good place to start due to the negatives contrast. The test strip indicated a 7 seconds exposure would provide an acceptable first print.

When I pulled the paper from the soup it did not look right even with the red light on. It lacked contrast almost flat in appearance. (fig 1 Ilford paper). I opened a box of Foma and exposed it at the same settings (fig 2 Fomatone), again it looks soft with a cooler tone to it. Finally I put a sheet of Kentmere (fig 3 ) in the easel and exposed it at the same setting. Found it! - this matched the test strip. What a difference! - it suggests a grade or two more contrast! 
FG 3.  Kentmere RC
 developed in Multigrade

I was surprised at the contrast between the Kentmere and the others was so striking. The paper developer I used was Ilfords Multigrade it has been in the processor for about a month. I note the time it takes for the first sign of the print to show - in this case 15 seconds - this gives me an idea of how exhausted the developer is. Also as the developer exhausts so the prints show signs of warmth. Once it reaches 30 seconds I tend to add fresh developer or change it.

 I did not intend to compare these papers - I was side tracked by my test strip. What I would suggest is that if your negatives are a bit on the soft side that maybe if you use Kentmere paper it may boost their contrast giving them more punch or should I say presence. I am not suggesting that you should change to Kentmere paper instead of setting the appropriate grade for the negative you are working with. It is something to keep in mind for those very thin and or flat negatives that do not respond very well when you cannot find a grade that works.

Fomatol PW paper developer.

Fomatol PW paper developer.
This small pack of paper developer has been sitting on the shelf patiently waiting for me to use it. I'm told it will produce some very rich brown looking prints. I think the time has come to try it.


The information on the packet:

    
Same size different amounts.
The developer is a slow working Hydroquinone that will produce warmtone images that verge on brown when used with Fomatone papers. This varies depending on manufacturer. You can get a bit more information about the developer 
from the Foma web site.



Mixing instruction: Dissolve big bag first in approx 750 ml of water at 20 c with continuous agitation. Then add small bag while continuing the agitation.
This makes no sense as both bags are the same size!!?

Figure 1
Ilford multigrade RC paper, developed in Multigrade.
Development: 2-3 minutes at 20 C depending on dilution. The more dilute the developer the stronger the image tone will be. The developing time is dependent on how many more parts of water you add to the stock solution. I.E Stock 2-3 mins, 1+1 4 to 6 mins, 1+3 8 to 12 mins. To keep the results consistent the developer should not be stored for the longer term.



 
 
 
 
Capacity:
 
 One litre of developer should develop 2- 3 sq meters of photographic paper. This translates to approx 210 sheets of 8 x 10. The number of pictures produced is dependent on the types and makes of paper used e.g. resin coated and or fibre base.

This little pack of powders makes up a stock/working solution of a litre. Which will mean for larger sheets of paper you may need to use two packs or dilute 1+1, this will extend the developing time and increase the tone of the final image.

Figure 2 Ilford multigrade RC paper,
 Developed  in Fomatol PW

The only bit of controversy with this developer is to determine which is the smaller of the two same size packs. If you lay the packs side by side it is easy to see which of the packets in fuller than the other or to be absolutely sure use a scales then there are no doubts. They could quite easily mark them A and B.

Making the developer up is straight forward:

Fill a mixing jug up with 750 mls of water at 20 degrees C. while mixing in the larger of the two packets make sure you constantly stir it. As you mix it in it will have quite a gritty feel to it turning the water white, this is normal. It will start to go clear as you stir in the the smaller pack. The gritty feel to developer will start to disappear as well. Once both the powders are mixed together add a further 250 ml of water making it up to a litre. Keep agitating the water until all the powder has dissolved. You should now be left with a clear slightly tan tinted liquid. This is classed as the stock solution and is ready to use as it is. You can if you wish dilute it 1+1 or 1+3 for greater colour.

Large pack of powder
added first.

I'm going to compare Fomatone PW against a semi fresh Ilford multigrade developer already in the slot processor. I am curious to see how much tone, different makes and types of photographic papers would show at stock strength. I poured the developer into a tray ready to use.

 I set the enlarger to grade 3 and the lens to F8 after exposing two sets of test strips the base exposure was set to twenty two seconds with a further forty seconds of burning in. I should have chosen a more straight forward negative for this comparison.


Figure 3 Adox MCC FB paper developed in
Fomatol PW for 5 Minutes
The first paper into the soup was Ilfords multigrade RC gloss into the slot process ( Fig 1) for comparison. Figure 2 went into the tray of Fomatone PW. Would the developer tone this paper? Resin coated papers can be difficult to tone.

Fomatone PW is billed as a slow working toning developer and at stock strength it was suggested that the image would take two to three minutes to reach full exposure. The Ilford paper was near enough spot on to the second of three minutes and has a warmth to it. Don't forget that RC papers tend to reach full development far quicker than it's FB brother.

Figure 4  Adox MCC FB paper developed in
Fomatol PW for 12 Minutes.
So I upped the stakes with Adox MCC FB paper this would really test how long the image would take to appear. Figure 3 shows what happened when I took the paper out after 5 minutes. I should point out that MCC is not a warm tone paper and yet here it exhibits a light chocolate brown colour.

I changed tactics for figure 4 it is the same paper as 3. FB paper can be manipulated far more than RC papers. So for this print I doubled the exposure time by adjusting the aperture to 5.6. I could shorten the developing time by pulling the paper out early. It should mean that the blacks in the image appearing more quickly. As it turned out it took twelve minutes for the image to be fully produced. If I had not increased the exposure I suspect that it may have taken a further twelve minutes to reach the same point of development. Of all the pictures made this is my favorite as it comes closest to what I had in mind. So far PW has demonstrated it is a very slow developer and a test of how long I can stand still rocking the developing tray. It is a shame that my darkroom is not big enough to allow a chair. How slow the developer can be I'm about to find out.

Figure 5
   Fomatone MG classic matt - Chamois 542 11 
Developed in Fomatol PW for 20 minutes 
Being this is warm tone developer I am about to see how it enhances a warm coloured paper. I chose Fomatone MG classic matt - Chamois 542-11. The papers base colour is cream to start with so what would a warm tone developer do.? Twenty minutes later - yes you read that right! - it is still under developed for my taste, all though it is richly toned. (Fig 5) Even with the red light on the colour was striking. 
 





 
Figure 6 is the same paper developed in multigrade to show how much tone the Foma PW has added. I must admit I prefer it in it's natural state.

Figure 6.
 Things to note:

  • When mixing the developer up it will turn the water white.
  • It does not matter that the pack is out of date. In this case by four years! Powder chemicals have good keeping qualities.
  • It will significantly stain the tray you use.
  • It is a very slow working developer and will require patience.
  • I would suggest purchasing two packs at a time.

I like the tone that the Fomatone PW has produced and think it gives the paper a more contemporary warmth.



The developer will clear when
the smaller of the two
packets are added.

Since writing this article Foma has discontinued its classic matt Chamois 542-11 which is a shame. The closes paper to it is Ilfords Art 300 it is slightly more tinted look.
