Maco Ecomat FB dryer

Ilford FB papers are notoriously difficult to dry flat and the FB Classic papers that Ilford introduced in 2014 are no better at this! That’s my only complaint about their fine papers.

The dryer has variable heat and I dry my prints against the drying cloth on the cover. The dryer gives a dull gloss similar to what would be obtained from air drying glossy FB paper.

The dryer is still available by special order, but only in this one size, direct from the German manufacturer Hans O. Mahn and Co for €1095 (February 2018), it is currently called ‘MACO ecomat dry press 51x65cm’. Here’s a link: www.macodirect.de/labor/papierentwickung/trocknung/maco-ecomat-trockenpresse-51x65cm

It weighs about 15kg and needs a space a bit bigger than the paper that it dries, around 80 x 70 cm should do. It’s about 16cm high when closed.

Replacement drying cloths are still available for €149 (February 2018) and in regular use should last over 10 years, judging by my experience. Here’s a link: www.macodirect.de/labor/papierentwickung/trocknung/maco-ersatztrockentuch-fuer-ecomat-trockenpresse-51x65cm-tp5060

If you’re looking for a dryer for FB papers I suggest you take a close look at the Maco Ecomat dryer.

They include some examples of what you can do in the darkroom with a bit of time, practice and some patience. The video covers basic techniques of contrast, cropping and paper surfaces as well as pre-flash, split grade, toning, split toning, combining negatives into one print, making reflections when none existed in the original negative.

I hope it keeps you out of mischief for a few hours!

Making your first black and white print Tutorial
This tutorial includes how to make a test strip and how to make a print using a single exposure. 2 of the videos are included here.

Split Grade Printing the Ilford Way
Split grade printing should be the normal way to make prints on variable contrast papers like Ilford Multigrade. One of the new videos describes the technique.

These 3 videos summarise what I cover on my darkroom printing workshops. Here are the videos:

The papers are sensitive to blue and green light (as well as white light of course) but not orange and red. This means that they can be handled for exposure and processing under red or orange coloured lights. These are called safelights.

Types of photographic darkroom papers
There are 2 basic types of darkroom printing papers:
Graded: these are papers with fixed contrast. If you need to change the contrast in a print you will have to buy another box of paper with different contrast. This has led to a considerable reduction in the use of these papers and a reduced range of grades being available to buy. Ilford for example only make grades 2 and 3 for Galerie graded paper. Film needs to be processed so that the contrast of your films is roughly matched to the contrast of the paper.

Variable Contrast, VC: This type of paper gives you all the contrasts from grades 0 to 5 in one box. You change the colour of the light used for the exposure to change the paper contrast. A leading example of this type of paper is Ilford Multigrade and it has effectively replaced graded papers for creative printing.

RC or FB:
RC stands for resin-coated and is much easier and quicker to use. You will be making good prints more quickly with RC paper.

FB is for Fibre-Based. This gives the ultimate quality, maximum black density and archival lifetime. The increase in density as prints dry is very difficult to judge, even for an experienced printer.

It is much more difficult to use properly so I would suggest that you don’t use FB papers until you are making good prints with RC paper.

Surfaces:
Glossy gives deepest blacks and hence greatest contrast. There will be lots of reflections off the surface making fingerprints and other marks highly visible. It is not good for situations with lots of handling of prints.

Matt gives dark grey not black when compared to a glossy print. It is best for high key images or those which don’t have strong blacks. It is also good for displaying prints in areas where there is lots of light from many directions as it will not pick up reflections on the surface.

Pearl is the compromise between glossy and matt. It is good for framing prints without a window matt as the lightly textured surface prevents patterns forming between glass and print surface. It also easier to handle as any marks are less obvious.

If you are new to darkroom printing I suggest you start with RC Pearl paper.

How photographic darkroom papers work
There is no ink in a darkroom print! The density in a black and white darkroom print is silver metal. The silver is coated with gelatin to hold it in place and is often referred to as a silver gelatin print.

Contrast comes from having different levels of silver built up across the print. With VC papers it is controlled using specific colours of light. The useful colours that make variable contrast papers work are from blue to green light. In practice, filters are used to block particular colours.

Ilford Multigrade papers contain 3 emulsions with different sensitivities to blue and green light. All 3 emulsions have the same high sensitivity to blue light which gives lots of density and this increases the contrast. Using blue-green or green light the sensitivity of each emulsion varies so this produces less density and in turn lower contrast.

In practice, exposure times are shorter using the complementary colours of yellow and magenta. A yellow filter blocks out most of the blue light for low contrast, magenta filters allow blue light to pass through resulting in high contrast.

Filters
Filters for VC papers come in various shapes and sizes. Some enlargers have VC heads with the filters built-in. These are the easiest to use. Under lens filters and above lens filter drawers are quite easy to use too. The filter kits cover all of the grades from 0 to 5 in ½ grade steps. Under the lens filter kits are usually provided with a universal filter drawer that will fit any enlarger. 

Colour Heads are not so easy to use but tables of filter settings for different enlarger heads are provided in every box of paper. The yellow and magenta filters built in to every colour head enlarger can be used but lack the high contrast and will not give grade 5 and some struggle to reach grade 4. Also, exposure times vary as filters are changed unlike filter kits where exposure times are constant as grades are changed.

An advantage of VC and colour head enlargers is that they produce diffused light which reduces hair and dust that would be visible on prints from other types of enlarger.

The Process
To make a black and white print there are 2 essential chemical steps, Develop and Fix, with an optional Stop between them. You will need 3 dishes and they must be labelled to avoid contamination of the developer. A trace of fixer in developer can lead to inconsistent results.

Use the times and dilutions stated on the products that you buy. The chemicals are usually liquid concentrates. You just pour out the required amount of each, add water and stir.

The first solution is called a developer since it develops the latent image formed in paper by the enlarger exposure.

The second optional step uses a so-called stop bath. The only purpose of this is to stop development by converting the print from being slightly alkaline to slightly acid. This has the effect of extending the life of the fixer so that more prints can be processed (fixer is much more expensive than stop bath!). Note, water cannot be used as a stop bath, it must be weakly acid and commercial products are either acetic (smells of vinegar) or citric acid (odourless).

The final chemical step is fixing with a fixer solution. This is essential as it makes the print stable to light by removing surplus silver that hasn’t been used in forming the image on the paper. If you skip this step your print will go black when you turn on the room lights!

You can now turn on the room lights.

The final step is to wash your print in running water. RC papers only need about 5 minutes and the temperature has to be above 6ºC for it to be effective. FB papers need at least 30 minutes.

The print can now be hung up to dry for an hour or two on a washing line over a sink or bath, or dried with a hair dryer which usually takes a few minutes. FB papers will need many hours to dry.

During each step agitation is crucial. Don’t just put the print in the dish and wander off, rock the dish to move the chemicals around the print. This avoids local exhaustion of the chemicals in contact with the print.

Note, the basic photographic chemicals for black and white printing are not hazardous when used correctly. Follow the health and safety recommendations on the chemical packaging. 

Basic Test Strips
In order to make a print you need to choose an exposure time by making a test print. In fact you usually cut strips of paper about 2 inches or so wide so that one sheet of paper does several test strips. Take the negative carrier out of the enlarger.

Place the strip of negatives into the carrier shiny side up and select the negative that you are going to print.

Put the carrier back into the enlarger and turn it on. You should be able to read the writing at the edge of the film when you turn the enlarger on and view the image on the baseboard. If it reads backwards the negative is in upside down.

Put your paper easel on the baseboard directly under the lens and adjust the blades to the paper size you are using. This holds the paper flat and stops it moving during exposure. The blades give white borders to the print that can make your prints look quite smart.

Move the enlarger head up and down until you have the desired size image for the paper being used.

Fine-tune the focus with a grain magnifier then turn the enlarger lamp off by switching it to timer mode, assuming it has one!

Set the lens aperture to f8 or f11 for best sharpness.

Select filter 2 or 2.5 and place into the filter drawer. This is a good starting point for normal contrast negatives.

You are now ready to do a test strip.

Exposure testing
Having cut your piece of paper into 2 inch strips take one and place on the easel in part of the image so that each of several steps will have light and dark areas, if possible. You will do about 4 to 6 steps on the strip of paper so roughly work out how big each step will be. In the example here we will use 4 equal steps.

Expose the whole strip for 10 seconds.

Take a piece of card (thick enough that light can’t penetrate!) and cover up about a quarter of the length of the strip. It’s best if the paper and card surfaces touch to avoid light piping around the edges and on to adjacent steps. Stop the paper moving as you slide the card over the top of it by sticking the strip down with BluTac or similar.

Expose for a further 10 seconds.

Cover up another quarter of the strip and so on for 4 exposures.

Process the test strip as described above.

There is an alternative test strip method which doubles the time for each step. This can be useful if you don’t have a clue what the required exposure time will be. The steps would then be 10, 20, 40 and 80 seconds in this example. Hopefully, you will quickly get the feel for the likely range of exposures and the simpler method described can be used most of the time. 

Note, you should avoid exposure times over 50 seconds or so as the papers rapidly lose sensitivity here. Open the aperture ring by one stop to halve the exposure times instead, for example, use f8 instead of f11.

Print Evaluation 
First you need to look for the first step that shows small areas with some black, not dark grey.

If you have steps where one is too light and the next too dark choose an intermediate value.

If in doubt do another exposure with smaller steps.

If needed as a final check, expose an entire strip at these settings before committing to a full sheet of paper.

Check the strip again for blacks across the area.

If the strip exposure still looks reasonable make a print on a full sheet of paper at this exposure with the same filter.

Now judge the overall image for exposure and contrast.

If there are large areas of white the contrast is too high and you need to reduce the grade.

If the print has lots of detail everywhere with little or no bright areas try increasing the contrast using a higher grade.

If you have too much black with no detail try reducing the exposure time.

Print judgement is something that comes with practice, but the more you print the easier it becomes. The only shortcut that I know of is to come on a darkroom printing course with me!

If all else fails with exposure and contrast changes affecting the whole print then local adjustment of the density and contrast are needed. This uses simple techniques called dodging and burning or a different basic technique like split-grade printing. But that’s for another article!

Ilford FB papers are notoriously difficult to dry flat and the new 2014 papers are no better at this! That’s my only complaint about their fine papers.

I don’t like high gloss prints so my prints are dried against the drying cloth on the cover which also ensures that the print dries flat. Without this prints can crease as you stick them down. The dryer gives a muted gloss similar to what would be obtained from air drying glossy FB paper.

The drying cloth on my dryer had come to the end of its life, as judged by the hole towards the edge of the fabric. In truth it should have been replaced earlier but it still worked without blemishes to the print surface.

A quick look on Google found the web shop, www.macodirect.de, for the German manufacturer. Even better they had the required drying cloth in stock, complete with felt underlay. My wife Jan had already worked out how to make one using the old one as a template so this saved her quite a tricky job.

It arrived today, 4 days after ordering. It fits perfectly, as you would expect. I will just put a print or two through it to check all is fine then it’s full speed ahead again!

If you’re looking for a dryer for FB papers I suggest you take a close look at the Maco Ecomat dryers.

The bonus this year is the weather, lots of sunshine and little rain. It doesn’t seem like Derbyshire at all! There’s still room on the calendar for more, if you’re interested just get in touch for a chat.

Today I walked to Buxton to run the Gallery in the Gardens in Pavilion Gardens. Clear sunny skies and temperature of 24°C, a bit of a breeze on the tops made it a good temp for walking, as I walked the 6 miles here this morning. It will be warmer as I walk home tonight.

Here are some photos from the photo course on Saturday, all taken by Jan using a Nikon D90.

The DeVere came with an old 500C keypad that doesn’t have any memories so I switched it for the spare 500CPM keypad that I happened to have. This is what I’m used to using and having 9 memories makes all the difference when using split grade printing, as I do for every print that I make.

The 504 also has the advantage of baseboard focussing. My old Durst 138S doesn’t have this and making big prints can be a bit of hassle getting the focus correct, I can’t reach the focus knob next to the lens while looking down the grain magnifier on the baseboard.

The Durst is still a great enlarger though, I bought it from the ex-Ilford Head Printer Mike Walden 4 years after he retired from Ilford. He decided that 40 years working in the dark was long enough for anyone and sold all of his personal darkroom gear, mostly to me!

I’m still getting used to the DeVere. It is easier to use than the old one but I prefer the bigger baseboard and negative carrier on the Durst. The Durst chassis is much older than the DeVere but the head on the Durst is newer. They both work the same though.

That makes 2 enlargers with Ilford MG500 systems in my darkroom, as well as 3 Durst M670’s. I either do 1-to-1 private courses or group courses for 2 people, so you have even more choice when it comes to enlargers. The MG500 heads print all negatives up to 5 x 4 inches in size. The M670’s print negatives up to 7 x 6 cms.

Thank you Mike for your hospitality on collection and generosity. Hopefully it will now give many more years of use as I have no plans to switch to digital cameras from my Mamiya 7’s anytime soon!

I finished printing and cleared up by 4pm. I now have another 70 contact prints to work from. We are on our way south for a family bash tomorrow and I have them with me so that I can mark them up with my trusty red Chinagraph pencil. Once I have done this It’s easy to pull together the scanning list.

They give me new shots of the Lake District, Yorkshire Dales, Norwich, Norfolk Broads and Newbury. Just need to find some time to do the scanning and Photoshop editing to get them on the web site. Will try and have some as prints for next show; Stonor Park near Henley on Thames.
