Looks like coffee not multigrade?

Ilford multigrade paper developer
It has been sometime since I have entered the orange light district. Upon entering recently the darkroom looked a mess, something I don't remember leaving.! It could do with a good clear out and clean up but that will have to wait. I'm in desperate need of print therapy. I do a quick clean of the enlarging easel and lens. Then check the chemicals in the paper processor.

 The developer has gone a very deep brown, the stop and the fix look OK they were all fresh the last time. Even so I change the fix. Now what to do about the dev? In the end I emptied out half so I could refill it with fresh. Your thinking 'it's knackered why bother?' but I prefer the tone you get when fresh and old are mixed together. The slight depletion gives a warmth to images I like.

Contact prints.
I opened a partly used bottle of Ilford multigrade and poured out some of the contents to be met by a liquid the colour of black coffee! That's a new one on me never had that before! Which makes me think - ( expletive ) Mmmm! I'll use it anyway see what happens. I do not have a choice as I do not have a fresh bottle on the shelf.


First test print
It was my intention to get on with some enlargements, but I decide to contact print three sets of freshly developed 35mm negatives as this will test the strength of the developer. It turns out that the dev is more depleted than I had expected ( you were right). The contacts are taking nearly two minutes to reach full development and that is a very long time for resin coated paper, which is usually fully done in a minute.

Before I start work on the enlargements I drain another litre of developer and add some more 'black coffee' (developer) to the mix. Then load the first negative into the enlarger. I find I can be a little apprehensive getting ready to do my first print after a long absence. I'm not sure why, as it always works well.  

Second test print

With the first test strip exposed, into the dev it goes. Ah! I was a little quick off the mark the developer has not reached 20C yet as it takes a little over a minute to fully develop. As it turn out the test strip shows that I was being optimistic with the F8 aperture I had set. The test strip is not showing any exposure in the first four, five second segments. Indicating it will take more than fifty seconds to reach a base exposure time. That's far to long so, I adjust it to F5.6 effectively doubling the light. The next test strip I start at fifteen second and go on from there at five second intervals. Sometimes I can over develop the negatives and this is the first indication of it. Which I don't mind. The trick is not to over do it as it leads to loss of detail. That's better! the test strip was fully developed in less than a minute.

How the areas were dodged showing
how much extra light was added to each
section

With the second test strip in the holding try I take my time looking at the segments. My vision for the image has already formed and with a plan. All I need now is get off the fence and decide what time the first print should be exposed at. I plump for twenty two seconds at F5.6 at grade three on Kentmere RC gloss 9x12. I have already noted that the Ro9s negatives are a little softer than the normal Ro9 and not as grainy.

I need to point out here that I always work from wet test strips and automatically add a dry down factor without thinking. Ansel Adams used to tell a story of how he came to recommend that you should always work from dry test strips and prints. He had produced a particular photograph that was a delight to the eye so much so that he went ahead and printed a large number of them. Only to throw the whole lot out the following day as they did not look as good as when they were wet. I don't very often do long print runs and if I do it is not until I have studied the print dry in day light.

Final print.

As I look at the photograph in the holding tray with the rooms light on I can see it is over exposed, dull and muddy looking. It lacks the luminosity I have come to expert from analogy prints.

I already new that the picture would need dodging to recreate my vision. I inspected the test strip again and cut the overall exposure time to fifteen seconds. I then dodged the foreshore and wooden posts while I added a further seven seconds to the water above them and the sky.

 
Again I studied the second print in the holding try. Although it had improved, It still fell short of my vision. It is a good idea to have a notebook to hand in the darkroom so you can keep track of the adjustments. I have now cut the overall exposure to eleven seconds. I will add a further seventeen seconds in three sections. First of all I will add four sec's from the edge of the water to the rest of the picture. Next, seven sec's from where the wooden posts finish and finally seven more seconds to the upper part of the sky.


These last adjustment have improved the image no end. Bringing it very close to what I had in mind and giving it the luminosity it lacked. There maybe some fine tuning needed when I print it on FB paper but I will only do that once the photograph is fully dry.
With the three prints side by side
You can see how the image has changed.

The coffee coloured developer has worked well even with the heavy oxidation of liquid. A change in colour does not always mean it has lost it's potency. Now that the photograph is dry the image has a very gentle warmth to it. I have found that the tone a photograph takes is more pronounced once it is fully dry.

Split grade printing the next step dodging and burning .

Top grade Zero
Bottom grade five
The use of split grade printing has changed the way I work in the darkroom. Yes it takes a little bit longer having to produce two test prints, but in the long run it cuts down the amount of dodging and burning needed to achieve a finely toned photograph. I have also noticed a luminosity that has been missing from my graded prints. It has also shown me that it is an advantage and not a waste of paper to make full or half page test strips. You get a better understanding of how much more light is needed for the high lights, so you can build this into the first full print of the scene. This saves time and paper having to reprint it again and again to get it right.

I find that my more contrasty negatives are more easily printed using the split grade method, giving more control of not just the tones but also the contrast. Burning or dodging my prints has been reduced considerably, allowing me to add more detail at the extremes. 

So at what point should you be burning in or dodging? The grade zero exposure being the most important one is also the stage at which you should be making your adjustments. If possible you should be including them for the grade five test strip. By doing this you will have a better understanding of how the contrast affects the corrections and make allowances for them in the final print.

Some of you reading this will be thinking it's all to complicated and not for you, Dodging and burning is about having confidence in your ability, once you have done it and seen how it changes your pictures for the better, you will be wanting to do it every time. I enjoy this part of the picture making process, it always reminds me of a composer on the rostrum encouraging certain section of the orchestra to bring out his interpretation. Only you are using light to enhance what you had in your minds eye.

Burning in graduation times
OK I'm going to keep this simple just to give you the idea of what to do. I have only used grades 0 and 5 but in certain cases other grades maybe more appropriate but that is for another time.

Producing the prints:

I produced a soft toned (grade 0) test print at five second intervals. When it was dry I compared the segments to determine which would give the best overall toned exposure and how much extra light would be needed for the sky. I chose seven seconds for the whole picture, this allowed the street scene shadow to keep its detail without it blocking out. A further twenty one seconds would be added to the sky. With the main exposure done the sky was burned in. For this I used two black pieces of card held together to form a V shape. The trick with dodging (holding back the light) or burning (adding light) is to keep the mask moving otherwise a hard line will be left. I gently moved the card backwards and forwards lingering in places to give the sky a graduated look. The times on the picture are there as a guide.

Now I placed some black card over the masking frame to protect the picture from any stray light, while I adjust the enlarger to grade 5 for the contrast exposure. The first segment was covered and then exposed at two second intervals there after. Again when dry I chose 3 seconds.

Final print
With the all the times combined a full print was made. There are some short comings; firstly the build on the left could do with a bit more burning in to bring out the texture of the wall and if I wanted to be really picky the sky could do with masking in more precisely which would mean cutting a mask that mirrored the buildings outline.
 
The idea was to keep it simple and to show what could be achieved with the most rudimentary of masking off.

Tilting the easel


Is mainly used for correcting those converging verticals in pictures of buildings. The reason you get sloping upright lines is because the camera has not been held vertical to the view.  View cameras (large format) are the only cameras that can keep the film plane vertical and look slightly upwards at the same time with out this distortion. You can buy a shift lens which has the same ability or do it in Photoshop.

When enlarging you negative you can correct this by using a tiling easel.  Simply lift the easel by the appropriate amount and rest it on a block. Remember that you need to lift the easel on the side that has the converging lines. When doing this you should set the smallest possible aperture providing the greatest depth of field. When making the enlargement, part of the picture may be lost, it is just a case of cropping the picture to make it square. After processing the exposure may be different between the top and bottom this can be corrected by dodging to even up the overall exposure.
