T max 400 a wonderfully smooth finish.

Whilst putting an order in and perusing a suppliers web site I suddenly had this urge to find out what the cost of using Kodak's T Max 400 would be in 120 format. I have no idea where this thought came from or why! Anyway I had a look and by chance it was out of stock. I still do not understand why I should want to use it. In the main I have not used film faster than 200 ISO for decades. I have been happy to go about my picture making at 100 or 125 ISO.

Some months later out of the blue I find myself buying ten rolls of 120 out of date Tmax 400 which just so happened to be part of a job lot. If I'm honest I would not have purchased them at all if it had not been for the Tmax. All I can gather is my creative subconscious has an idea of some sort that will reveal it's self over time!

I am no expert in the way the mind works but I get a sense of when it is the right time to get things done. I sometimes find myself sitting back waiting for that feeling to get on with projects, when it happens I find I am very creative for a short intense period of time. Once that need to be creative is fulfilled the project has to be more or less complete, which happened in this case with the images that accompany this article.

We had a pile of logs in the garden waiting for me to chop up when I had the time. They were starting to nag at me to get on with the job when I noticed the way a particular branch was lit - it brought out the texture of the wood in an interesting way. For some reason it also made me think of a severed arm the more I explored the pile of wood the more macabre it became to the point where another branch looked like a limbless torso. My god! my mind has gone into overdrive and it was not Halloween! It just goes to show how powerful your imagination can be - I could no longer bring myself to cut the wood up! 


Some weeks later I was looking out the window at the logs again - I know! But what struck me was the quality of the light. It was very bright in a soft way as though some one had put a soft box in front of the sun. I went out to look at the sky it was covered with very thin cloud, like a mist. All at once the idea for making images of the logs fell into place.

To make the images as surreal as possible I had to separate them from the landscape, which meant I had to set up a background in this case - I felt that white would do the best job. I worked as quickly as I could because I was not sure how long this wonderful soft light would last. I had no time to test the white background idea just go with the flow. The lumps of wood were very large and heavy for a set of still life images.

T Max 400 grain, film developed in RO9.
 As to what film I should use there were no second thoughts - the out of date T Max 400. I pulled a number of rolls out of the cupboard before I loaded them into my Bronica SQAi. I used my hand held light meter to check how bright it was. The rest as they say is history.

The light lasted the best part of the morning and a number of rolls of Tmax. Which was fortunate I was in a creative wonderland that stopped abruptly after about a couple of hours. The flow of ideas had gone so it was time to pack up and move on. The intensity of the project had left me worn out! The images do not convey the size and weight of the logs I had been moving around. It was time to sit down, regain my energy over a cup of tea and consider how they would be printed.

I was excited and apprehensive all at the same time. Excited to see how the negatives and prints turned out but also apprehensive at the possibility that the light readings could be wrong as there was not time to double check so the film could be empty of images. My other concern was with the development of the film. I had a time of 10 minutes at 1+50 for the RO9 I would be using. Having not used this film developer combination before I could not tell how well they would come out until the wet negatives were hanging up to dry. In these situations I process the film one at a time so I can adjust development if needs be.

I was shocked in a pleasant way when I first looked at the dripping negs. The detail and tone were superb. The superlatives kept coming as the printing got under way. The negatives have a super fine grain with great tone and detail. I printed them on Kentmere RC gloss paper because of the arctic white tint which tends to increase the contrast of the negatives. I would have used FB paper but I did not have any cool tone paper in stock so used the next best thing. I needed the bright white background to enhance the surreal look, not that they weren't that already.


It became clear that if I wanted to keep the stark white background then there would need to be some burning in of the light wooded areas to bring out the detail and maintain the softness to the shadow. It would have been criminal not to exploit all the fine details the negatives held. This extra work did not take away the Eminence pleasure it was to make these prints - even the ones that went wrong - believe me I make some stupid mistakes sometimes that I can't believe!

I really did not know what to expect from the T max 400 especially as I was using RO9 ( it depends on which manufacturer you use as some are finer working than others) not known for it's fine grain and less so with film as fast as 400 ISO. The grain produced is quite fine considering the developer used I suspect it would be even smoother with a developer noted for it. These T grain films really are a jump on from the more traditional emulsions. Is it better than Delta? it is difficult to say without doing a straight comparison between the two. I'm exceptionally pleased with the results.

Oh by the way the pile of logs are still there! Thanks to a friend the pile has grown in size and weight and will take even longer to chop up!

Ilfords Delta films A big surprise.


I read a lot of stuff in search of inspiration and ideas for this blog. And one of the strangest things I read a lot is the lack of willingness to push creativity. For example: 'I will only ever use FP4+ - I only make landscape images.' Why? I have never understood the idea of painting yourself into a corner, creatively speaking. I have been writing this blog for around a decade now, the one thing I have discovered is that choices, likes, dislikes move on naturally and to say never say never really only means for this period of time.

Delta 100 negs
Like wise I have never given Ilfords Delta range a second thought. Why? It just has not been on my radar. I have been happy making images using FP4+ and Fomapan 100 among others. All of a sudden I find myself saying to a friend that I will purchase his out of date delta. And now I have about 15 rolls delta 100 and 3200 120 format in a box on the floor waiting for me to use it.

 I have already exposed one roll of 3200 at box speed, which just happens not to be the rated speed of the film in this case. It is actually rated at 1000 ISO something I was not aware of at the time I used it. Which means that the film was pushed five stops, something of a first for me! I've also used a couple of rolls of 100 at box speed.

OK so what is so special about Delta film? It is Ilfords offering in the T grain category of film emulsions, Kodak call theirs T Max and Fuji Neopan. Known as tabular grain film, meaning that the shape of the silver halide is relatively broad and thin, with two well developed parallel faces. This leads to the crystal absorbing more light sensitive dye. It also reduces the scatting of light which increases resolution. This leads to a film that works in all sorts of lighting conditions. If you think about it, it is ideally suited for beginners, making it very tolerant to bad exposure.

Tabular crystals dissolve more slowly than traditionally grained films when it comes to fixing them. You are advised to increase the fix time as it takes twice as long for the film to clear when using rapid fix.

In truth I am not someone who can go out and make images of anything just to try out a new film. Even when it is well out of date, some of you may think it's a bit risky. I believe it is a waste of time if the images you make are not well composed and of subjects that you enjoy. After all a good image is easy to print and share. A project that would suite the Delta 3200 droped in my lap. I had the opportunity to photograph a number of five week old pups. When it came to photographing them they had all worn themselves out and were fast asleep. That is until I started making pictures! Its funny how noisy a Bronica SQAi with an motor drive can be in hushed conditions!

I was a little disappointed with the 3200, although it was very bright outside the room was a bit dark and on a couple of occasions I was down to 60th sec at F2.8 which is the minimum aperture for the lens I was using and as slow as I could go hand held. It was not practical to use a tripod as they had tucked them selves into lots of little cubby holes to sleep.





Print from Delta 100 ISO 100
I developed the film RO9 at 1+50 for the suggested time of eleven minutes. The negatives look a bit underdeveloped (thin) I will, for the next film, up the developing time.

When it came to printing the negatives the underdevelopment showed it's self on the segmented test prints. Indicating that 15 secs was the best exposure time. I chose to use Adox MCP paper set at grade 3. The enlarger was set to a height for 11 x 12 paper but the easel was set for 8 x 10 paper with white margins. I did this because there was a lot of dead space on the negatives. The down side is that the prints are a bit grainy. Something I should have expected to a certain extent seeing as I have used RO9 to develop them with. The final prints were a little soft even though they have been printed at grade three.

Having read the above it may lead you in to thinking it was a bad set of negatives. On the contrary I am very pleased with the results although a little disappointed with the contrast, but then you have to take into account that it is the very first time I have worked with this film. Fortunately I have more film to play with.

I have also exposed a couple of rolls of Delta 100 at box speed developed in RO9 and by comparison they are very punchy (high contrast) they remind me of the Fomapan 100 negatives I produce with the above developer. The 100 has produced super smooth looking photographs. Something I have been looking for for sometime. This may replace the need for a ultra fine developer.

Agfa film grain comparision.

This set of images proved more difficult than the last set of grain pictures. I think I need more practice or a better method.


Developer ID11
I checked back through my archive of negatives and found that over the years I have used four makes of developer with this film - ID11, PMK Pyro, RO9, and RO9s. 


The RO9s negatives were processed in developer that was more than the suggested best before time of three months. Although this developer was still viable it starts to produce a courser looking grain pattern than when it is used fresh.

Patterns of negative grain.

RO9 developed FP4+

Ever since I started writing this blog I have been looking for a way to show you what grain is produced by different developers. I have used a number of methods without success over the years. Until late last year when the need to show what the grain looked like raised it's head again. By chance I had my phone in my hand when the idea to use the enlarger and phone camera together came about. It is one thing to have a good idea it is another to put it into Practice.


PMK Pyro developed FP4+


A long time later I managed to get two good images from different rolls   of 120 FP4+ that I was happy with. They show a visible difference between the one developed in PMK Pyro and the other developed in R09.

 When I have more time I will make  images of other film developer    combinations if you are interested.

RO9 and the lens less camera.

All the photo's side by side
Over the last few months it looks like I have gone RO9s mad. I have! it is the new toy in my developing arsenal. I'm enjoying the quality of the negatives and not having to make up developer every time I want to process a film. It is still new enough for me to think I have forgotten to do something as I pour the liquid in the developing tank. With all this effort being spent on this developer it has made me think about its brother RO9 and it's attributes in connection with pinhole photography.

Image from PMK Pyro developed negative printed
on Ilford multi grade RC gloss.
Let me explain: RO9 is described as having a number of qualities, the main one here being, high acutance producing a very sharp looking image - a bit like sharpening a digital file in Photoshop. The idea that this developer may do this to the processed negatives has been a splinter in my mind for sometime, that I have been compelled to dust off my Zero pinhole camera to find out if it does make a difference.

Printed on Kentmere RC gloss
I always feel very relaxed after I have spent time making images with this camera, I should use it more often. Anyway I loaded it with Fomapan 100 set to a 6x6 negative size.

 With the twelve images made it was into the darkroom to process the film. It was developed in the RO9 for thirteen minutes. The density of the negatives was as expected. With the new crisp looking negatives hanging up to dry what should I compare them with? After searching back in my archive of negatives it looks like the only other developer I have used when making images with the Zero is PMK Pyro. This developer is not known for it's sharpness but at least I did not follow the method through by using an afterbath. Which can add a further softening of the image by adding tone.

Zero pinhole set to 6x6 120 negative size

My comparison was never going to be very scientific. It was always going to be a case of would I be able to see a difference with the naked eye. You may feel that the comparison is unfair and to a certain extent you are right. To counter this I will compare the RO9 negatives with those produced with a lensed camera. If the RO9 is a sharpening developer it should be noticeable.

When looking down the focus finder at the different developed negatives the difference in grain structure jumps out at you. The PMK Pyro neg's are so smooth it is difficult to bring the the grain into sharp focus. Where as the RO9 grain looks like boulders. So does this defined structure indicate that the negatives will be sharper?

I enlarged the negatives to fill the 9 x 12 Kentmere RC gloss paper, instead of the smaller 6X6 square format of the negative. I wanted to see if the grain would be more exaggerated by doing this. To my surprise they lack the graininess I was expecting. In fact they are very smooth and defined.

Conclusion:

With all the photographs laid out side by side is there a visual difference in sharpness? The straight answer is Yes but not enough to say if you want sharper lens-less images use Ro9. When you compare the PMK negatives with the RO9 ones there is slightly better definition to the edges of the subject giving you the sense that the pictures are sharper. It does not take away that distinct soft focus you get with pinhole cameras. If you then put a lensed print beside the RO9 developed picture you can see that it is very soft in the pinhole tradition. It shows that when using RO9 there is a sharpened quality to the photographs.

How well will RO9 Special/ Studional perform a month on from dilution.

Nikkormat FT2 camera

 The developer has been diluted for two months, it's time to see if there has been any degradation of the solution over those months. It was not my intention to put the developer on the spot by using an out of date film and then to pick a make of film that I find difficult to get good results with but the die had been cast by the fact that a film had been loaded into my FT3 some time ago and then promptly forgotten about.

 

Developer  has changed colour
So what happened? To start with as I poured the developer into the graduate it was a gorgeous turquoise in colour. This is the second time I have used this batch of Studional so I have not a clue what this colour represents, it was clear when it was fresh. For all I know this could mean that it is dead and buried and the best thing to do is pour it away. RIP. I carried on anyway no point stopping now. I need to know what the colour represents. Good or bad?
 

This batch of developer had been diluted 1+15 but according to the data sheet it should be 1+30 for Fomapan 200 processed for 12 minutes plus 20% increase for the age, as the table indicates. Seeing as I have not taken any notice of the indications this will not work I throw caution completely to the wind and cut the development time in half and add 20% which I ignored developing for eight minutes. What the hell!
 

Contact print Fomapan 200.


So what did you think happened? Well! Yes, you are wrong. I am astounded these are some of the best negatives I have made with Fomapan 200 they are crisp and punchy or should I say they have a very good tonal separation, producing some rich blacks as the photographs that illustrate this post show.

I should throw caution to the wind more often if the results are going to come good like this!

Using RO9 special/ Studional as it was intended.

Negatives are FP4+ and Fomapan 100
I have had the opportunity to use RO9s/Studional as it was intended. Multiple development from the same batch of developer (1 litre will do 12 films). This is a new departure for me, I prefer the single use type. I was a little apprehensive with this decision but gathered four 120 format films together so I could put to the test the assertion that you can develop any number of film on the same day it was diluted without having to add a compensation factor for each film involved, as you do with other developers. This was something I had not heard of before.

Made using a Zero multi format pinhole camera.
 The two makes of film were FP4+ and Fomapan 100 in both cases at box speed. It just so happens that the dilution for these films is 1- 25 with a big time difference - four minutes for the FP4+ and ten for the foma 100.


As mentioned before in another article the developer has a syrup consistency to it as you pour it out. At this point I must add a warning because of the concentrated nature of RO9 special/Studional you need to take precautions when pouring it out to make up the working solution. I have found out to my cost that if you get it on your hands it has a nasty bite. Something I have not experienced when mixing up other developers.

Made using Bronica SQAi.
 With the developer made up the first film to be treated was the FP4+. I was curious to know how well the short process time would work. This will be the quickest I have ever produced the latent image. The actual time suggested was three and half minutes - you need to be careful of short times when it comes to processing film, so I upped it four minutes. Not a lot I know but it could mean the difference between a reasonable set of images and a good set. I can report that it was a good set of negatives with good density across the whole film. The next film out of the processing tank was the Fomapan 100 processed at the suggested time of ten minutes. Again a good set of negatives in fact when held up against the FP4+ film they looked Identical in density. To cut this short the third and fourth films were the same in look as their predecessors. I was not expecting such good results.


Made using a Bronica SQAi.
  The method I used was made up of my trusted inversion procedure and a returning of what was left of the 600 mls of developer back to the storage bottle. Let me explain, when you pour the developer out of the tank there is a a certain amount of fluid lost to this action. It is only a small amount but can be enough to stop the top edge of the film being fully immersed. With this in mind I poured the developer back into the litre bottle and then poured it out again into the measuring cylinder before each film processed. I could have just topped up the difference. This is me erring on the side of caution. This action may have rejuvenated any depletion that had occurred but I suspect that this is not the case with this developer.

Contaminated by wetting agent?

Developed in RO9 but it is not the developer.
When something unexpected happens while you are processing your negatives, it takes a bit of time to get your head round it. This happened while I was processing a number of rolls of film in R09 and using it's special brother.

 The problem has shown it's self by producing very blotchy negatives affecting two rolls of the six film developed. When this happens in a run of developing it is difficult to work out what circumstances are different enough to point a finger at.

Please bear in mind that the elimination process was written after I discovered the culprit.

Fomapan 100 negatives developed in RO9
Process of elimination:

  1. So where to start? It is fortunate that the negatives involved were not the ones processed in the RO9 special. The RO9 developed one's were. This made the investigation more straight forward in that I have a better understanding of how RO9 works.
  2. Was it the developer? It was made up seconds before it was used in the usual way.
  3. What about Stop and Fix? Both were freshly made up minuets before use. So it cannot be one of the three main players? As they are all fresh.
  4. OK what about the method? No difference there either I used my usual inversion sequence.
  5. Processing tanks? Well I did press a tank into use that I have not used in a long time because of the quantity of film that needed to be developed.
  6. Could that be the answer?
  7. Did it affect one make of film in particular? No it did not, again this could have been a fortunate coincidence in that a roll of FP4+ and Fomapan 100 show the same affect. If it had only happened to one make it could have been construed as a manufacturing fault.
  8. Water? It was fresh and clean and there had not been any notices to say there was a problem with the drinking water.
  9. That leaves wetting agent? Hold on now that points to something I noticed when I was using PMK Pyro some years ago, I had a roll of film with the same sort of pattern. I put it down to the developer which I have
    Film FP4+ developed in PMK Pyro
    not used since. Thinking back to that time I had noticed that every time I opened the dev tank to pour out the developer there were a lot of bubbles in the top. That looked soapy and diminished with each step of the process which would suggest developer. I did speak to a number of other photographers at the time who suggested it was a developer fault. Although I stopped using the developer substituting it for ID11 and the problem disappeared was not convinced at the time. I changed how the kit was washed after each processing session. After a while I also stopped adding wetting agent to the tank. Using a different tank with it already added. Dunking the reel in by it's self and then soaking the reel in a bucket of water with a good resin afterwards.
Looking back I think when I pressed the other developing tank into use I mistakenly picked up the one I had been using for wetting agent. The resulting blotchy pattern is the result of its contamination.

This print was made from the same contaminated
Negatives. note no blotchy marks.

Conclusion:

Having eliminated all the other possibilities and no matter how silly it may sound the wetting agent is the culprit in this case. It has this time affected nearly all the frames on each film, when it happened some years ago (after checking the negatives) only certain frames showed signs of being blotchy. Which would indicate a weak contamination of the film process. This is only the second time I have had this problem in all the years I have been developing film. It just goes to show that something as innocuous as soap can cause so much trouble if it is not washed away conclusively after every processing session when added to the developing tank. My suggestion is to put wetting agent in a separate container and add the reel and film to it and not the other way round.

This picture shows that the blotches are prominent
In the sky but not the foreground.

When printing the affected negatives you cannot see the blotches when looking down the focus finder. Even though the contact prints show it quite clearly.

All the photographs that appear with this article were printed from the dodgy neg's. As I mentioned not all suffered the soapy demise.

RO 9 Special developer.

Recently, I had an unexpected back log of film to process It can be difficult to find the time to do them especially when it is more than a couple of rolls. Anyway a gap opened up so I dived into the darkroom to load two of the rolls ready for development. As I reached for the RO9 my attention was attracted to a couple of bottles of developer standing behind it. RO9 Special and Studional which as it turns out are one and the same along with Rodinal Special. While I was boxing up the first couple of film I had a rush of blood to the head and decided to give the RO9 Special a try. There was method in my madness.

At the time of my decision I had no background knowledge of this developer apart from how it was marketed and the information on the side of the bottle which is sparse to say the least. The blurb stated that RO9s was the finer bread brother of RO9 which was what attracted me to it in the first place. Part of my madness had been influenced by a cassette of HP5+ I had been given to process.

120  FP4+ Negs Developed in RO9s
In stead of jumping in at the deep end with both feet, I thought it prudent to check the very short developing times printed on the side of the bottle by processing a roll of 120 FP4+. Because I have a tendency to slightly under expose my negatives the suggested time of three and a half minutes at a dilution of 1 to 15 was increased to four. I used my standard agitation method of twelve inversions for the first thirty seconds and then four every minute. As there was no indication to the contrary. As soon as the fix was poured out of the tank I checked to see if they had developed properly. From what I could see they looked perfect. I had not intended to do a grain comparison for this film, it was purely to see if the times on the bottle worked in my favour.

The info on the side of the bottle for HP5+ suggested four minutes at 1+15 - I processed the film for five; as it turns out it was a good move. I think the negatives would have been a bit thin otherwise.

I have now researched process times and developer information for RO9s Something I should have done first with a visit Digital truths Dev chart for more times. They tell you to look at Studional.

HP5+ Negs developed in RO9s
 
Something else I had not been aware of was once the developer had been made up you could use it again. I had a suspicion it could be used again because the concentrate had a syrupy look when I poured it out. In fact you can process up to twelve rolls of mixed formats per litre. The most interesting thing about this developer is that there is no time compensation if you do more than one roll of film on the same day. You only add a compensation factor the longer the working developer in stored. Up to three months.


Developer Data:

RO9 Special/Rodinal Special and Studional.

Characteristics: Fine grain sharp negatives with good contrast. Once diluted can be stored for multiple use. Short process times.

Mixing instructions: Dilute concentrate with water 1+15

Number of Film per Dilution: 10-12 35mm or 120 format per Litre.

Temperature: Is best kept between 18 C and 24C with + or – adjustments as needed to the length of the development time.

Agitation: Tilt the tank for the first minute continuously and then once every minute. You should avoid developing times under three minutes.

Shelf Life: Concentrate should last 2 years in original bottle with no air gap. Once Diluted it should last 3 months without air gap in it's own container.

Time increases for multiple use: To keep speed yield and contrast consistent the diluted developer should be kept in brim full tightly capped bottles if this is achieved the following will apply:

Almost forgot the reason for the rush of blood to the head if you had not already guessed it was to do with the 35 mm HP5+ I find that this films emulsion tends to produce rather grainy negatives with standard RO9. As I intend to enlarge these negatives to 9 x12 the finer developer should make the prints less grainy. I am pleased to say the strategy worked, the negatives have a much finer grain than the standard RO9. The proof of the pudding will be in the printing of the FP4+ and HP5+ negatives. I will share more prints in another post.
