Making your first black and white print

Darkroom Papers and Printing
The key to good black and white printing is control of the contrast. To make it easy to follow, numbers have been assigned to contrast levels and these are referred to as grades. The scale can vary between manufacturers but typically the contrast range is numbered between grades 0 and 5. Normal contrast is around grade 2 or 3, low contrast is 0 and high contrast is 5. As the grade number increases so does the contrast.

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.

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 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 6ÂșC 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!

New Print Lecture City Light Finished

I have just finished pulling together my latest lecture. It's called City Light after my book of the same name. Lots of hints and tips throughout and explaining how I pull my pictures together.

Its a print lecture, as usual. Ilford Photo generously donated the Ilford Multigrade FB Glossy 20 x 16 inch paper for me to make the darkroom prints on. It's very expensive to do print lectures now and this sort of help makes the difference between preparing a new lecture or not. I also included a few 24 x 20 inch prints for good measure.

The first half is all cities from my City Light book. It's based on my lecture on how to photograph cities that I presented at PhotoLive in London last year with quite a lot of new prints added in.

The second half is in 2 parts, the 205 mile Alpine Pass Route in Switzerland that we hiked last year followed by New Zealand and a few Far East city views including Sydney and Hong Kong.

I made the last 5 prints yesterday and mounted, spotted and trimmed everything. This morning I finished the running order. There are 45 prints in each half, 90 in total. This is the most I have ever included in a 1.5 hour lecture. In all I used just under 300 sheets of paper, including spares, and around 18 days printing in the darkroom.

The pile of 90 prints in my City Light lecture

It's a nice feeling when a new lecture is finished and is ready to go!

All set now for the world premiere at the North Cheshire Photographic Society in Poynton on 30th September 2014!

For information, I give lectures across the UK to all sorts of clubs, so if your club would like me to visit and give one of my lectures please contact me through my website. I'm also listed in the PAGB (Photographic Alliance of Great Britain) Handbook under lecturers for LCPU and NEMPF but I will travel anywhere as long as you pay me!

Vienna in the Sunshine

Jolly nice day in Vienna today. We took lots of photos. New places as well as some previously visited in poor weather in last 2 days.

I have some decent shots and hopefully they will appeal to people who know Vienna. Coincidentally someone asked for pictures of Vienna at our last show, at Crowthorne in August.

One of the places revisited was Karlskirche, with a reflection today.

So many iconic buildings in Vienna have scaffolding and shrouds around all or part of them. Tricky finding angles to avoid the distractions.

Jan was pleased too as we found time to visit the Hotel Sacher for the very special Sachertorte. It was excellent, allegedly!

Home tomorrow.

Vienna Wet and Dry

Today was a big day for us in more ways than one. Lots to photograph after the day time washout yesterday and lots of walking. In fact Jan's Fitbit said we walked just over 20 miles!

The distance came from walking to the Vienna Giant Ferris Wheel in Prater Park. This is the one in The Third Man film and is one of the main tourist attractions so was on the shooting list for 2 reasons.

I wanted day and night photos so we went over this morning as it was dry with rain forecast later. Then we walked there again late afternoon, in the rain, arriving in time for dusk which then led into the night photos, between showers.

In all I spent well over an hour this morning and an hour this evening photographing the wheel.

It was a half decent day between showers so I photographed lots of the iconic buildings too.

Forgot to take stuff on my phone so just a couple of shots from Belvedere.

Tomorrow is also forecast to be changeable so fingers crossed for more good skies.

In total I took 11 rolls of Ilford FP4 120 film, making a total of 13 with last night's 2 rolls.

Analogue Photography Alive and Kicking in Vienna

On our way back to our hotel for a break in the photography proceedings I noticed this shop window. Analogue photography is obviously still thriving here.

A large part of the shop window was given over to Ilford pinhole cameras, all three of them!

I'm not the only dinosaur in Vienna!

Vienna in the Rain

Jan and I are in Vienna for a few days. We seem to be just in time to catch the monsoon season! Lots of rain.

We arrived here late morning. There was a 2 hour spell in early evening just as it was going dark when it stopped raining and we even saw clear sky for a few minutes.

I ran off 2 rolls of Ilford FP4 120 film with my Mamiya 7 camera around the Hofburg area, New Town Hall and the cathedral.

I took a few on my phone too, converted to black and white in Snapseed,  to give you an idea of what it's like.

Thunderstorms, heavy rain and sunny spells are forecast for the next 2 days. I get the impression the forecasters are hedging their bets!

New Drying Cloth for Maco Ecomat TP5060 Dryer

I have been using my Maco Ecomat TP5060 for drying fibre based darkroom prints since buying it new in 2002. It is fantastic at drying Ilford FB papers flat and takes up to 24 x 20 inch sheets.

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,, 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.

Photographs for Photokina on Latest Fibre Based Ilford Papers

Ilford Photo asked me if I could provide prints with my images on their 3 new fibre based Multigrade papers for Photokina. This is the worlds largest photo and imaging fair, held every 2 years in Cologne in Germany (Tuesday 16th to Sunday 21st September 2014). My prints will be the only prints on display to promote these new papers. It feels quite a privilege to be asked to both make the prints and use my images.

In June Ilford supplied a box of 50 sheets of each paper, the window mounts and the frames. I printed my photographs and mounted onto conservation card as usual and then finished the framing, all signed on the print and on the window mount as usual.

These were all printed on 24 x 20 inch paper with images of 56 x 46cm (sorry about the mixed units but the paper is supplied in inch sizes and the images were in metric narrow black aluminium frames of 80 x 60cm). From each box 1 sheet was cut into test strips and I used 4 or 5 sheets to make the print for Ilford and a couple of spares in case of any problems when it came to the print finishing (not needed as it happens, all was fine).

Photokina is now almost here so it's time to show the 3 pictures.

Here are the 3 photographs on the new Ilford Multigrade FB papers framed and hung on our gallery wall. All of the original photographs were taken on Mamiya 7 cameras with Ilford FP4 120 film developed in Ilford Ilfotec DDX film developer diluted 1+6 for 9.5 minutes.

Print details:
The prints were all developed in Ilford Multigrade developer at 1+4 dilution for 2.5 minutes, then the usual Ilford Ilfostop stop bath at 1+19, Ilford Hypam 1+4 fixer, water rinse, Ilford Washaid for 30 minutes then final wash.

All are split grade prints, the only technique to use for creative printing with Variable Contrast papers such as the Ilford Multigrade range. In my view single exposure prints and pre-flash are old-style techniques for graded papers.

My prints are realistic to what I saw at the time I pressed the shutter button. The small amount of manipulation that I use is purely to compensate for small areas of brightness and shadows that need help to be rendered realistically.

The Photokina set of prints

Spanish Steps at Night, Rome
Taken in December 2013 at night after a rain shower cleared the steps of people. Taken with the 43mm lens and a 6 minute exposure at f16 which removed most of the people walking across the view, just the odd bit of ghosting!
Night shots work well on FB glossy and the new Classic seemed sharper and even easier to work with than MGIV FB, my usual paper.
Printing: main exposures 14.5s grade 1/2, 3s grade 5
minor tweaks: +15s grade 0 bright wall on right, +5s grade 0 top of fountain.

Leadenhall Market in London at night. 
This is used as a covered footpath and is a busy arcade during the daytime and early evening, especially weekdays. Taken late evening on a Saturday in March 2011.
Warmtone paper is great for old architecture such as this. This was probably my favourite of the set, it looks great on the Warmtone paper.
Printing: main exposure 12.5s grade 1 with -3s to cobbles, 10s grade 5
minor tweaks: +10s grade 0 left hand roof bright area.

Wolf Creek View, Colorado
Snow covered trees and the view to surrounding hills from the ski area in southern Colorado with the greatest snowfall in most winters (about 12m), January 2011. An orange filter was used to darken the deep blue sky.
Cooltone with its blue-blacks was chosen to match the cold snow and ice of the main subject.
Printing: main exposures 5.4s grade 1 with -1s bottom left and -1s peak, 7.8s grade 5
minor tweaks: +1.5s grade 0 bottom right

...and here it is in the dish being processed.

Vertical Panoramics

I have added several new vertical panoramics of Italian towns and cities as well as a couple in London.

They are on the Recently Added pages for the next month or two and can also be found on the relevant Cities pages.

The Gallery pages are all driven by Keywords so just click the Refine Search tab on each Gallery page and you can select country, city, state/county or keyword. This then creates the pages with all images matching the search.
