Picture Post, Planes

For me making images of aircraft is heaven. It is the combination of two loves. As you can see these are not the bog standard images you see, they are about the poetry of flight.

Enlarging lens revisited

Recently black and white photography magazine has been celebrating it's two hundredth edition which gave me impetus to rediscover what was in some of those back issues. While thumbing through one issue, an article about enlarging lenses caught my eye, reminding me that I have been meaning to revisit the subject.

I have written a couple of small articles: Enlarging lens and which aperture  I re-read both before writing this one so as not to repeat myself. But that is not going to be easy as the main issue with enlarging lenses is quality. The rule of thumb is to choose a lens of six or more elements. The Componon-s and Rodagon are two modern designs that work very well - they are two quality makes of the few still available new.

Looking down a focus finder at F5.6- F8
In the 1970s Nikon special optics division set about producing a darkroom lens second to none ( Apo-EL-Nikkors ). It was done in a one off batch, releasing a number to the market over a ten year period until they were all gone. It has been said that at the end of this period they did consider doing another run but stopped doing so because they would have had to sell the lenses for £12,000 each. I do not know if this figure is true or not. If it is, it will have made the original runs price in the thousands and therefore out of the reach for most of us.

The enlarging lens has one job to do and that is to project the the image from the negative to the paper perfectly. The one hindrance to good enlargement method and creativity is poorly maintained or ignorantly used enlarging lens practice. It is not good enough to think if you close the lens right down, like you would a camera lens, that you will increase the sharpness of the image. The rule again is to close the lens down by two F numbers. In a lot of cases this produces the optimum sharpness. One stop more may result in a softening of the grain structure. This does not mean that you will notice a softening of sharpness with the mark one eye ball as the image is projected onto the paper. Like a lot of things in photography the kit is made to a greater quality than can be seen in normal life.

Focus finder
Enlarging lenses should not be treated as second class citizens as they are several time better in quality than the camera mounted counterparts. They do their best work in a very narrow range of magnifications. For 35mm negatives the lens is optimized to 10x its size which equates to an enlargement of 10x8. As you go up the format scale this decreases 6x6cm lenses 6x and 5x4in 4x magnification. As you push past the optimal point it increases the possibility's of grainy photographs. This is not to say you should not push beyond this point as experience has shown. You can negate this by using ultrafine film developers.

Grain at f11

How do you see which is the best apertures to use? You need to complement your lens with a good focus finder. This magnifies the grain of the negative so you can see it. The best way to use the finder is to have the enlarging lens fully open. Place the finder in the middle of the baseboard. While looking down it at the grain, adjusting the bellows until it separates into little defined specks. This will mean that you now have fine focus.

While still looking down the finder shut the lens down a stop at a time. There will be a point where the look of the grain go's slightly soft and becomes softer the more you close it down. You should remember that you are still at optimum focus. To test this you can try to adjust the sharpness in most cases it will get worse and become to difficult to regain any sharpness until you go back to the optimum aperture.

Grain at F16 looking down the focus finder.

What has been described above is my experience with one of my 35mm enlarging lens. I will point out that it is not a well known make. It is one I use often. The softening of the grain in the focus finder is not transferred to a softer looking image on the baseboard that can be detected with the naked eye but you will start to question whether it is affecting the quality of your images. The only way you will know is to borrow or buy a better quality lens and do a comparison.

When considering buying a lens you should spend as much as possible to ensure that you get a good to very good lens. Knowledge that the lens is not what you expected will impact on your photography subconsciously.

Finding the edges of Eukobrom AC

One open ,One untouched.
I have some good and bad news concerning Tetenal's Eukobrom AC. I have been pushing the developer to find it's limits. Without knowing where the edges are you cannot be sure that you are getting the optimum usage.






Used and depleted




The good news is that two litres of diluted developer at 1 to 9 stored in a slot processor will remain usable for up to six weeks. Obviously this will vary depending on your circumstances. Also as the developer gets older the solution becomes more brown. Along with this it imparts some of this colour to the photograph by producing a subtle chocolate brown warmth in this case with Kentmere select RC gloss. A paper I have been using alot.






The bad news is, while I have been involved in seeing how long a working solution will last, I forgot to mark the stock bottle with an 'opened on date'!. As a result 800mls of unused developer has been thrown away. The first time I have had to do this ever! 
Continence from open
bottle

    
I discovered this 'error' at the start of a printing session. The existing developer was tested for usability and found to be no longer viable. So I made up a new batch to find that this was also depleted. I was suspicious that the open bottle was off by the colour but made up a new batch anyway. In the past with other traditional developers the colour does not always indicate that it is exhausted. It took time to find out for sure as the new developer was producing a very soft test image without any contrast. I was using Kentmere paper, not known for being on the soft side and very quick to produce an image when placed in the developer, seconds in fact. In this case it still was not right after two minutes. After several attempts it was dumped. Not impressed to say the least.




Test Prints from open bottle of Eukobrom AC 


Not to worry I had a new unopened bottle. However on pouring the new bottle into the measuring jug this was brown in colour as well. Not the slight orange colour I was expecting. Now I was angry. I made up a batch anyway and to my surprise I was met with a well developed test image. Fully toned, great!



Developer from fresh
bottle

It took over an hour to get to this point what with one thing and another. My temper mellowed as each successive photograph left the developer fully toned.


Will I use the developer again? I still have the best part of a litre left from a dodgy opened bottle that has an 'opened on date'. As long as the contents are viable I will use it again. As to re stocking it? Not sure? It is just as well I keep some of my old friends in stock.

fresh bottle.


Test print in fresh developer..
I did email Tetenal a long time ago to find out if they had any suggestions as to why this should be the case but have had no answer, I can share with you at the point of writing there is still no answer on posting.

Paper Kentmere RC gloss.
The images that appear in this gallery have been processed using Tetenals Eukobrom AC developer on a number of different papers.

I would like to thank Tetenal for there interest in and re-blogging of the first look post. It was a big surprise when they got intouch.

There is a new post on Eukobrom to be published not all good news.

Double grade printing.


From time to time I find it strange the way events come together! for instance, I was in the darkroom working on some prints that I could not get the sky to burn in properly. There was nothing unusual in me burning in the sky, most of the photographs I produce have had the skies enhanced in some way. But this time I could not get it the way I wanted it.


The strangeness in this case was that a few days before, I was reading a thread on my favourite forum about how to deal with whited out skies when printing. I took part giving an account of my method of dealing with it. One of the other contributors suggested split grade printing. But when he described the process it is more akin to double grade printing - this is where you use another grade to bring out part of the image that will not burn in at the grade you are using.


All the circled images needed double grade printing.

The process:


The contact print in this case suggested that the stone work of the building and sky were under exposed when compared to the reflection. The segmented test print (grade 2) proved this by indicating that it may need to be burned in for an extra twenty seconds above base exposure of thirty seven seconds. Even with the extra light it did not make the difference. After a further print and forty seconds burn in, it still was not right. I decided to see if changing to a harder grade when burning in would make the difference.

With the discussion still fresh in my mind I opted to use the double grade method to see if it would solve the problem I was having. I normally would have used pre flashed paper but that would mean starting all over again with a pre-flashed test strip. I chose the simpler route of dialing in a harder grade, in this case 4, before burning in the sky and face of the building.

The red area indicates the over lap area of the mask.
Something to consider:

When using this method certain negatives can produce a grainier look to the picture which may not be to your liking and you need to be careful not to knock the masking frame when changing the settings and using the mask.

The burning in method:

It takes practice to get this method to look natural, which is easy to master when you have a nice defined area without things like buildings poking up above the horizon. A piece of card is needed to use as a mask. You do not need to use black card but if you have some all well and good. Otherwise any card will do, if one side is brighter than the other you should always make that side face the lens to reflect the light back. In my opinion you should make the mask smaller than the site that needs covering. Because the card is kept moving it will make up for the under size when used with an up and down motion. If you don't you can end up with a lighter shaded area a bit like an out line you would get if it was still. When you get it right it is very satisfying.

 Result:

I used forty seconds at grade four to burn in the building and sky. How did I know it would work? I further considered the segmented test print, took a calculated risk and listened to the little voice in the back of my head. In other words I went with the creative flow.

Trouble in the darkroom


My darkroom is a very personal space, the only acknowledgement to it being standard is the separation of wet and dry working areas. It is just big enough for one person to work in comfortable. A bit of a glorified closet really! which has meant I have had to find ways of making the space work hard to meet the needs of both wet-and dry sides working areas.



One of the things I have had to do is to put the 12 x16 paper processor under the work top on a pull out shelf. It was done originally to save space but has proved to be inspired in a way I had not foreseen. Being able to look down on the print process has made it a more relaxed way to work. Keeping the work top clear for other wet side needs has not worked so well, the top is being dominated by the tray I use to put the tube covers that keep the chemicals fresh in the slot processor. It was a large tray so that the tops could be spaced far enough apart to stop cross contamination. 


However, it all came to a head when I wanted to try a new print developer and use it with a tray so I could monitor when the first signs of the image appeared, then transfer it to the processor for stop and fix. I should explain that the darkroom does not have running water. I usually part fill a tray with water to put the fixed photographs in then wash them at the end of the session in the bathroom. Anyway I had the water tray precariously balanced on top of the slot covers in their tray as the rest of the top was taken up with the developing tray. It must have been a good day as I did not manage to tip the whole lot over myself. 

I now seriously considered ways of storing the slot tops that would keep the worktop clear. It came to me that the best way was to stand them on end. My first thought was to use a number of metal clips attached to the wall. I cannot understand why I had not come to this conclusion sooner. Once I had thought about it. It was not such a good idea as fix attacks metal. I decided it would be better to use plastic, so took some measurements, sat down and did a number of drawings of a tray that would hold the tubes upright. Then thought about how to stop cross contamination, so added sections to the base. Once I had refined the basic look and measurements I showed the idea to my mate at Plasweld, he helped to simplify the design and added a splash back to stop chemicals running all over the place when loading the tops into the stand. 



A few weeks later the stand is finished. It works very well and has freed up lots of space on the worktop allowing me to work more safely. Such a simple idea that has made a big difference.

Welcome to the New Year

 On a grey and dull day I am going to say a big, bright THANK YOU to all my follows, subscribers and supports for visiting the blog over this last year. Views are up big time even though it has been a bad year personally.

As is the custom for this time of year I have a new header picture that shows a hand picking up or putting down an Agfa Isolette I will leave it up to you how you interpret my intent. If any of you have any suggestion please share your thoughts.

As I sit here writing this, it is peeing down with rain, which has inspired me to set up my pinhole camera to make an image that will take eighteen minutes to expose. Not the longest exposure I have made but getting there. This is     the start of my rediscovery of the wonders of         pinhole photography and the Zero camera in         particular which I hope to use more this year         instead of leaving it in the camera bag. A new       years resolution of sorts!

   Talking of new year resolutions photograph wise     -  have you set any? I don't as a rule but this        year is  going to be different I have two things I    would like  to achieve one I have already              mentioned the  other is to spend more time in        the darkroom  printing, something that I can          neglect. I find it  difficult to spend anytime at all    during the  summer months in the darkroom I        do not like  wasting time inside if the weather is    bright and  warm, even in the evenings. I              suspect I'm not the  only one. What are your thoughts? 


I'm looking forward to seeing you all again this year. Don't be shy if you drop by - have a chat (leave a comment) - always interested in what you get up to. I shall leave you now as my mistress the darkroom is calling! I will chat with you all again later. Before I leave I would like to wish you all the best for the year ahead.

Living with Tetenal Eukobrom AC

Developer
Tetenal new Eukobrom AC is proving to be a delight to work with. I did not realise how much of a irritant the smell of the developer was until it had been removed from the equation. I no longer have developers nose where the smell lingers long after I have left the darkroom. 

In an early article on this developer I had a couple of questions: 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. One of these has now been answered, that is it's keeping qualities. I have been using it in my slot processor, at the end of each print session I leave the developer in the slot and cover it with the lid. The amount of time between each print session varies a lot from days to weeks sometimes months.

Slot processor
 Two things have come to light. If you leave the developer in the slot you should give it a stir before you start using it again. The active ingredient can separate out dropping to the bottom. I was caught out thinking that the developer had come to the end of it's working life because it had been left for two weeks. Something I did regularly with Ilfords multigrade without loss of usability.


Something else I have not experienced before was a black and white crystalline substance on top of the stop bath. It was a very heavy build up making it difficult to remove the top off the stop. The stop it's self was clear and still at the level it had been left at, turning out to still be working even so I changed it. This maybe an interaction with the vitamin C - something to keep an eye on.

The other question about the warming of the prints as the developer depletes still remains unanswered. This due to the fact I have not processed enough prints with the fresh developer. Once I notice I'll let you know.


 
Finally I have used this developer with a number of makes of paper now - RC and FB, natural, warm, cool tone and tinted papers - With great results, so if you have not tried it yet, do so! you can get it in 250 ml shots which is More than enough to get a feel for the way it works and looks.

Fading face?

One day later


I don't know about you but sometimes my mind wonders when I am processing photographs in the darkroom. I just can not help it, especially when an FB paper is involved, as sometimes it can be minutes till it is fully developed.

It was on one of these occasion that I started thinking about how long it would take for a developed image, but not fixed, to disappear. I have always thought it would be seconds once you turn on the light. Don't ask me where I got this notion from it is almost folk law among film uses. It is known that if you accidentally do it with film it all go's black straight away. Well the truth is, it can be saved if you are quick.




So what about photo paper? Firstly unexposed paper go's pink in day light and not black as I was expecting. The longer it is in the light the pinker it gets till it go's a pinky brown colour.

OK! a developed but not fixed image also degrades the same way but the image does not fade to black ether. In fact there is not much change a day later if left out on the table.


What is the biggest surprise of all nine months later and the image is just visible. You must bear in mind that it has not been in full day light all the time. I did notice that it had a couple of books on top of it for a time. It has well and truly surpassed any of my expectations. Just go's to show what you think you know may not bear any relation to the facts.
