Light metering?

For years I wanted to obtain a Bronica and when I did it was a very happy day. The SQAi has done a lot of travelling over the years; in all sorts of weather and across many different terrains. It has let me down on a couple of occasions but I do not blame the camera, overall it has been a great bit of kit. It can be a pain literally on long treks as it is no light weight, even in its lightest configuration.

I have not always been happy with the camera. When I first had it I could not get used to the back to front image which was really frustrating at times. I was not happy with having to use a hand held light meter either. I know! why did I
purchase it in the first place? Boyhood dream of some day of owning one? It has taken sometime for its use to become second nature, but now that it has, my picture making has become more fluent.

Along the way, my light meter use has changed; with some experimenting, I have found that two readings is better than one over all, making white bland skies with monochrome film a thing of the past. I, like you, have tried to solve it by using black and white filters from yellow to red and graduated neutral density filters to name a few. All of which are now gathering dust some where. Really and truly all you need to do is take a second light reading. Of what? The brightest part of the scene which in most cases is the sky and the amount of time it takes to do this makes it a no brainer. In fact you could have taken several in the time it takes to read this.


An understanding of Ansel Adams zone system helps to produce better negatives.

The picture right give a rough idea on how it works.

I have metered skies that have been as much as six stops brighter. In these cases, would it mean shutting the lens down by three stops to allow for it? With a little bit of help from the zone system you may only need to allow one stop to improve the detail in the sky, this would lead to better detailed negatives. The extra information would lead to more easily produced photographs.

Yes you can bracket your exposures which is a good way of learning what works best for you but as a long term method it is a waste of film. The idea is to know what works so you can get it right first time.


On average I have found that the skies in my pictures are about two to three F numbers brighter, meaning a slight adjustment to the exposure before pressing the shutter will produce more detail in the sky on the processed negative, without making the main part of the image too dark. When it comes to printing, whether burning in or holding back, depends on which method you prefer to use in the darkroom. My working method leads me to add light (burn in) more often than take it away (hold back). The sky is not always the brightest part of the picture, I'm using it in this case because it is the most common complaint with developed negatives and to keep my explanation simple.

The following pictures show what happen when the sky is taken into account:


120 format Film FP4+, 6x6 negative,
 Developed in ID11 ,
Printed on Ilford multigrade RC gloss,
 Developed in Ilford multigrade.





This picture was metered for the piper. I did not take a second reading for the sky. I have been unable to burn the sky in hence the white out so to speak.















120 format film FP4+, 125 ISO, 6x6 negative
Developed in Ilford multigrade developer
printed on multigrade RC gloss.





With this picture I closed the aperture down by one F number to allow for the sky. For example from F.8 to F.11. As you can see the clouds have been picked out. With a bit of burning in (adding light) The sky would have more contrast therefore stand out.














120 format Fomapan 100 ISO, 6x6 negative,
Developed in RO9, Printed on Ilford multigrade RC
gloss, Developed in Moersch 6 Blue.


This is a badly scanned photograph but it does illustrate how well the clouds stand out.

It was a difficult scene to meter. The lighting was changing quickly. The light reading for the sky was indicating a difference of three F numbers in brightness more than the overall reading.  In the end I only shut the lens down by one F number. It is a straight print without any burning in.

Thinking in Black and white?


I don't know about you, but I find it difficult to get back into the swing of things after a break. I find it hard to get my brain out of park. It would seem that the longer I get in the tooth the more likely I am to make the silliest of mistakes. Take earlier in the year for instance.




One Sunday afternoon we thought we would take a trip out to the Humber bridge. The day had turned very warm with a light breeze and rolling clouds. Ideal for making pictures. Earlier that day I had cleaned my SQAi and loaded up all my film backs with fresh film. Not unusual in it's self, except one of the backs was loaded with an out of date colour film. I placed this back on the camera and thought no more about it.



It was a great day to walk across the bridge and along the way I made pictures of whatever took my eyes fancy, happy in the knowledge that they would make good mono-prints. After making twelve pictures I changed the film backs with one loaded with FP4+ and continued on my merry way.



When unloading the film backs at home I discovered that the unmarked back had colour film in it and not the Foma 100 I thought I was using. Ah! How would these pictures work in colour? The reason I ask this is because I think and see differently when using black and white film. Or do I?




An unexpected chance to test what I have been saying and doing. When the pictures came back from the lab, the first thing I noticed was the way they had been composed. In fact the colour does not add anything to some of the pictures. I would not have made any of these pictures in this way had I known it was colour film. It would have been a different set of pictures altogether.

FADU 2014

The year book is out.

Hopefully this is the start of a new era of year books from the film anddarkroom users forum (FADU). Earlier in the year Ian a member of FADU expressed his desire to have the year book started again and enquired if any of the other members would be interested in taking part. To his surprise there was a ground swell of enthusiasm for it to be reinstated. A boost to its reincarnation was Les Mclean's offer to curate and edit the book on behalf of the members.

This is the first book since Dave Miller the forums owner bowed out of producing the book back in 2012. There have been a number of calls by different members to get it going again but were not able to find anyone who had the time to get it off the ground. One of the main differences is that a number of members have gotten together to form a group to over see the submission process for the year book.

What makes this year book different from others, and the forum for that matter, is it's strict adherence to all pictures being scanned from photographs. Likewise for a picture to be included in the book, each associate was allowed to submit up to four photographs no larger than 8 x 10 in size. To be mailed to the submissions member no later than the end of October. They were then sent on altogether to Les Mclean for editing.

Another good thing about the submission process for the book was any member no matter what his or her level of experience, was invited to take part. I have to add that FADU is a very friendly welcoming forum who's members are always very willing to share their knowledge no matter who or where you are in your analogue journey.
So to the 2014 edition of the year book, i have to say there is a wonderful selection of photographs reproduced in the book. In the end, nineteen FADU supporters provided work for inclusion in the book. Not as diverse as previous years editions but a good number to start things going again. Of the seventy six photograph’s entered forty have been chosen. Representing all genre of photography.


Thanks goes to all the members who helped to make it a reality and a special thanks to Les McLean for taking on the editorial role. I think his involvement gave the project the impetus it needed to make it a reality.

The Monochrome print and the colour enlarger.

Many years ago I was in a position to purchase a medium format film camera. This led to a complication in the darkroom in that my then current enlarger was for only 35mm film. An extra expense I had not budgeted for! At that time multigrade headed enlargers were quite expensive second hand and a bit thin on the ground. By chance 'the other half' noticed an ad in the local paper, it was for a medium format colour enlarger that came with some other bits to do with colour printing. I had not considered that a colour enlarger maybe just as good. The person I spoke to did not know what size negatives it took. So going to have a look was a gamble but then I only had to go round the corner. To my surprise it was all in mint condition and the enlarger would deal with negative sizes up to 6 x 7 - I was hooked! Apparently the seller had only used it a few times and decided to go digital. We struck a deal and the rest as they say is history.

Once the enlarger was home I dismantled it and gave it a good clean and checked it was all in good working order, not that I expected to find a problem. The big surprise was how dusty the inside was. It was gently cleaned with a soft damp cloth and wiped dry so as not to leave any residue marks. 


The next thing I needed to know was how to set the filters values for use with black and white multigrade papers. I chatted to a friend who pointed me in the right direction. After a bit of digging in the library I came up with a number of values for different makes of enlarger my one included. I thought the values should all be the same. But have discovered that the values are a suggested starting point. I have a set of multigrade filters that I used with my other enlarger at least now I will not have to check them for dust.

 There is a lot of speculation on the subject of using colour enlargers with multigrade papers. They split into two camps - the purists that say the multigrade filters only give the papers true contrast and people like me who check things out for themselves. I am at an advantage in that I have used both methods. Personally I have not noticed a difference but then I have not done a like for like comparison. Would I do one? The only way I can answer this is to say If I was to become dissatisfied with my results I may check to see if there was a difference.
 
The following are the values for Variable contrast papers for different makes of enlarger. The values are for the yellow and magenta filters the Cyan should be set to zero at all times.

It has been many many years since I obtained my enlarger and the resulting prints I have produced with it I have been pleased with, so much so that I have not tested the accuracy of the enlargers filters with Ilfords set. If it ain’t broke why try to fix it!
Since writing this ilford have introduced multigrade five making the above tables relevant to multigrade 4 only.  when purchasing paper you should always check the manufactures tables that come with the paper for the latest filter values.

Mottled prints

The one thing I like about traditional photography is it can be unpredictable. Even though the method you use is tried and tested, guaranteeing to a certain extent, good results, when the unexpected happens there are a lot of questions. Checking the method and chemicals used is great when a clear mistake can be tracked down, but what happens when there isn't?

 Sometime ago I pulled a set of FP4+ 120 format negatives from the processing tank that at first glance looked normal. I was studying the negatives in their sleeve when I noticed that the grain was not as usual.

Anyway, I did no more about it until I printed a number of them, then it became apparent the grain structure was different, so much so that it gave the photographs a mottled affect. I was not impressed, however once the prints where dry I filed them away. 

I went back over the way I processed the negatives, checking everything, but could not find an obvious reason for the way they had turned out. To add to the mystery it was not present on all of them. At the time I had just started using a new batch of PMK Pyro developer. I asked myself a lot questions about: 'did I mix it properly?' 'in the right order?' etc. etc. but could not come to a clear answer. So I shelved the developer metaphorically and literally.

The reason I'm telling you all this is that recently I have been looking through some of my boxes of prints when I came across these pictures again. The funny thing is I now quite like those mottled pictures, so much so that I'm going to print some of the other negatives and do some reprints on different paper. I find it baffling that when revisiting prints or negatives that did not appeal at the time, either compositionally or technically, they have now come into vogue. It is almost as though you are not mentally ready for what your eye is telling you works. In other words you need to keep an open mind even if it is not what you set out to do.



Since writing this I have been reprinting some of the negatives making me question again whether it was a developer fault. There is only one way to find out. 

It is now 2021 and the fault is down to the backing paper in some cases if it is 120 format film.

Mature paper developer


Mature multigrade developer with FB paper.
Notice that it has a very subtle warmth to it.
I happened to mention to a group of dark artists that I use mature developer when printing my photographs. I was a little taken aback in that they did not understand what I was saying and possibly a number of you reading this will not either. Basically it means that I cut fresh developer with old and exhausted developer from other printing sessions. Not always from the same manufacturer. It is something I have done for years and have not given a second thought to.

The technical bit:

Starting with the papers light sensitive coating, they can be made from three materials Silver bromide, silver chloride and silver iodide. These are combined to make three types of coating chloride,bromide and chlorobromide. A number of other chemicals are also added to help things along. The way in which these chemicals are mixed together affects how the final print looks. Chloride rich papers are slower and warmer in tone. Where bromide predominates it leads to faster acting and colder toned papers. As a common rule the material named first has the most influence on the way the paper reacts. Bromide papers are the most light sensitive producing neutral or cold blue black tones.
Fresh multigrade developer with FB paper.
Although the picture is of a cold subject the tone
of the scene is cold as well.

The most commonly mixed materials found today are chlorobromide papers. They are a compromise between speed and colour. By adjusting the percentages of these chemicals the manufacturer can alter the tone from warm to cold and vary how sensitive to light they are. I have found that the new Kentmere RC papers to be very sensitive to light producing a cold look to the print. It's quick reaction to the developer means that full development of the picture can be achieved in less than thirty seconds when developed with fresh Ilford multigrade. Chlorobromide papers tend to tone better than Bromide. If you are going to use gold toner then a chloride rich paper is the better than bromide rich paper as it hardly responds.

This is was printed on Kentmere RC paper with
 fresh developer. It was fully developed in less than
thirty seconds.


Although the tone and tint of black and white papers are subtle it has a great affect on the viewers response. Neutral and cold tones tend to create a distance emotionally, a sense of looking in from the outside. While warm looking images draw the viewer in engaging them emotionally. There is a tendency to use these different tones for certain subjects, cold and neutral tones with landscapes, abstracts and modern architecture. With warm tones being used with subjects like portraits, still life and nostalgic pictures like churches and old barns. We maybe used to seeing them used in this way but there are no rules but those you make for yourself and even then they should not be set in stone. By learning to manipulate and control the tone of the paper you are printing with, opens up new ways of engaging the viewer in your vision of the world.


Printed on warmtone  FB paper using
a sepia tone developer. Again the warmth is
very subtle. when compared to the picture
above.
When talking about tone and colour of monochrome papers it is important to understand there is a difference between tone and tint. The tone of a paper is influenced by how much chloride or bromide there is in the coating of the paper. More chloride means slower warmer pictures.

Paper bases come in different colours/ tints such as off white, cream and variations on the theme. At one time warm tone papers could be made on a brilliant white base but these days the base paper has a tint to it, this allows the manufacturer to reduce the amount of chloride in the mix increasing the speed of the paper and still call it warmtone even though it is the tint we see. Tints are most noticeable in the high lights and tones in the shadows. Because the colour shifts are so subtle an untrained eye may not notice the difference until it is pointed out to them.


This is the most important bit when it comes to manipulating the tone of a paper. The main thing film and paper have in common is grain it maybe invisible to the eye but the bigger it is the blacker it appears. When the paper is placed in the developer the grain increases in size as it grows so it changes in colour. From a yellow to begin with it turns reddish, then brown and finally black which is the point of full development.

Printed on  Ilford multigrade FB paper.
 It has been developed in an almost exhausted developer
giving it a pinkish look.
This is valuable knowledge when it comes to changing the tone of a print for example: If you over expose your print more than the exposure your test strip suggests and then under develop the print by say a quarter of your usual development time this will help to increase the warmth of your picture. If you combine a warmtone developer and paper it will greatly increase the effect.

Now to the technical bit behind the mature developer. What happens; as the developer starts to exhaust, so it has trouble fully reducing the silver halides in the emulsion. This means the developer cannot turn the silver completely black therefore it leaves it in the warmer less processed state. You can induce this state by adding fresh developer to an old/ exhausted one which will leave your prints with a wonderful but subtle warmth. The old, new combination should only be used up to a dilution of one to one. Beyond this can lead to sudden exhaustion of the developer.

My new print washer at last.





When I started looking for a new print washer I did not think it would take the best part of two years for it to arrive. Basically I was looking for a new way to wash multiple prints at once without having to stand there and agitate them. Giving me more time to print. It would have been quite easy to go down the road and buy one off the shelf, but I wanted to put some of the knowledge I had gained into building my own.


I was not expecting it to take so long to arrive at a design I was happy with. It was always going to be a slot style washer which meant it would be a little more complicated to build. I was up for the challenge. The easy part was choosing the materiel it would be made from one of two plastics I had in mind. The next was settling on the size, it had to be the same as my slot processor 18” (460 mm) by 14” (360 mm). When starting a project like this you do not realise how many questions need to be answered before the project get off the page. For example: How many prints did I want to wash at once? How far apart should the slots be? What style of slot divider? For each set of questions I solved so another set would take their place. The most difficult ones to answer were what tooling would be needed.


Making sketches of what the washer should look like helps no end in solving some question quite quickly. By doing this it gives an insight as to what will be the difficult parts to put together. One of the difficulties turned out to be the design of the dividers and how they would be put together. This question remained a sticking point right up to the point of having to make the divides. In the end I settled for ones that could be removed, just as well I did because I'm not happy with the design. Having said that they work really well.



Since it's completion it has been in regular use and now I would not be without it. It has done what I wanted it to do - free me up from having to stand and wash each print by hand.

Loading a Bronica film back

college still life
On one particular trip I made into college I was met by my tutor who placed in my hand a Bronica 6x45 camera and a roll of film in the other. Then told me to go into the studio and make pictures of the still life he had set up. Wow! I had wanted to try out one of these cameras for ages, part of this enthusiasm was when I found out that the lenses were made by Nikon. Sadly later models used seiko lenses. This is not to say the quality is any less. At one time I was very keen on all things Nikon.


I placed the camera on the tripod and released the film door to load the film. Which stopped me in my tracks. “How the hell do you make this work” I was expecting it to load the same way as other 120 format cameras that I had used. A short time later the tutor came in to see how thing were going. As he approached he smiled and said “It does not matter how many students I give this camera to you are all stumped by the film loading”. He took the film back and reversed the backing paper over the pressure plate round and onto the other reel. It was that simple.

For those who are not familiar with the way you load film into the Bronica here are a few pictures to point the way.

Film backs can be loaded on or off the camera body.

To open the film back compress the two clips on the top. The door will spring open

Remove the film holder from the case.

Push open the film spool holders.

Place the empty spool in the lower holder this is the one with the winder on the side. With the fresh film in the top as shown pull the paper backing over the top.

Pull the paper backing all the way up and over the top

Thread the paper backing into the empty spool as shown

Using the winder on the side of the film holder wind the paper on

Keep winding the paper backing until the arrow shows and stop 

Place the film holder back in its casing and close.

Do not forget to set the ISO. If you use a number of different film tear off the top of the film box and slide it in to the window.

Trimming prints a method


I don't know about you but over the years I have found no matter how careful I am setting the printing paper in the easel before exposure, it can still come out wrong. I'm talking about making sure the the picture is parallel to the sides of the paper. It is something we all have to deal with at some point. The problem being you can not tell this until the paper has been processed by which time it is to late.



This means that the paper has to be trimmed true again. To allow for this I have increased the margins around the printed area and even the size of the paper. Which I think is a waste as I would prefer to use the whole sheet to print on. But aesthetically speaking I think the margin around the picture adds to the overall effect and stops finger marks getting on the image. Which leads on to another skill that needs to be mastered, the art of trimming your print parallel. At one time it did not matter what I did I could not get it right, that is until a friend introduced me to the cut edge principle. This is where you use the freshly trimmed edge as your straight edge for the next cut and so on round the print. Wow! what a difference it has made over the years.


The knowledge of this method has helped with the trimming of my FB prints that I stick to a pane of glass so they dry flat - described here in another article.
