Night photography

First posted 16 November 2009

Although the weather is turning much colder now here in the UK, I really want to get out and do some more night photography. I’ve not done any serious night stuff for a while now and keep seeing shots while I’m driving or at other inconvenient times. I try to make a mental note of the location with the intent of going back with camera and tripod, but you know how it is, it doesn’t always happen. So I’ve decided I’m definitely going out this week.

I prefer cool, slightly misty Autumn nights for shooting. This is because it gets darker earlier, giving me longer to work and the misty air separates the tones as they recede into the distance (known as aerial perspective). This gives a better sense of depth and drama to a scene and suppresses the bright highlights of distant lights.

Autumn also brings a colour change and the orange brown leaves reflect the street lighting better. This year I have missed the best of the Autumn colours as we have had some really windy weather, which has stripped many of the trees bare.

Coming back to night photography after shooting other subjects and styles for a while, I was thinking about approaching it in a different way this time. Previously I had shot mainly on 35mm and medium format. Now I think I would like to shoot on 10×8 using a 300mm 5.6 lens. This would be used at it’s widest aperture to give a very shallow area of focus which I think will accentuate the theatricality of the lighting, making each shot look like a stage set. I’ll post some images when I’ve done them.

If you are thinking of doing any night photography and the lights where you intend to shoot are the common sodium type, then you might find chart 1 useful. These are the starting point exposures for Ilford HP5 under ordinary sodium lighting (orange lights).

The much brighter high pressure sodium lamps which are seen along motorways and in many city centres are paler in colour and twice as bright.

Use chart number 2 for exposures with such lighting.

As can be seen from the charts, the exposures increase dramatically as you use smaller and smaller apertures, this is down to reciprocity failure. This is a problem with exposures longer than one second, where extra exposure has to be added.

For anyone interested in taking night photography further, I wrote a book on the subject which has now sold out, but you should be able to find used copies on Amazon.

    Firstly I can recommend Andrew’s book on Night Photography – mine came via ebay and I am sure a little patience would pay off there.

    Andrew have you ever used any of the Fuji films where reciprocity failure is said to be negligible and it may be possible to use 100ASA film and still get shorter exposures than HP5+?

    Amazing as always :)

 

Lith printing

first posted 8 November 2009

I had a visit from a friend the other day while I was doing some contact printing. He was asking me how a real Lith print looked, as he had only ever seen them in books. I told him that there wasn’t much to it, the technique is pretty straightforward if you are just playing around with it, the difficulty comes in trying to get repeatable results. His question made me remember how much I used to enjoy that particular type of printing, so I decided a demonstration would be the easiest way to let him see just what it was capable of.

I wasn’t that bothered about doing contact sheets that night, so I mixed up some old Kodalith dev which I’ve had for over twenty years (it seems to last forever) and chose a suitable neg. I couldn’t find any proper Lith paper, but remembered that old Kentmere Kentona worked well and Ilford Warmtone FB could be used too. The Kentona gives a very pink result which is very typical of Lith prints, but I’m not crazy about it. The Ilford warmtone produces a Lith type image, but isn’t ideal, it’s not really supposed to be a ‘lithable’ paper, the split isn’t as pronounced as with some other papers and you don’t get any pink tones. The image goes speckled in a nice way though and takes on a khaki sort of colour which I find attractive for certain images. The effect is often so ‘grainy’ though, that it can’t be used for large format negs unless you particularly want them to look like they were shot on Delta 3200 on a half frame camera.

One important point though, the RC version definitely doesn’t work, -you have to use the FB.

Here are a couple of examples, the first is on Ilford Warmtone and the second is Kentmere Kentona, both from a 5×4 negative;

Once we had a few prints I began to experiment with a few other papers. I tried Ilford Gallerie and Kentmere Fineprint VC FG Warmtone, which has a lovely quality when processed normally, -I think it has the look of a pencil drawing with the right image, it doesn’t have a deep black, but a deep pencil grey on a cream base. I was surprised to find that it worked really well as a Lith paper, out of the four non Lith papers I tried it was easily the best.

Here is an example;

The Technique;

As the Kodalith developer is no longer available, I ran some tests with the Fotospeed variety to check my dilutions and times. There was no appreciable difference at the strength I was using it, though this differed from the recommendations that came with the kit.

My own preference is to mix 50ml of A and 50ml of B into 900ml of water at 20?C.

To establish an exposure time;

Method A

Expose four pieces of paper (I cut a sheet of 10×8 into four equal 5×4 test pieces) to a range of times, one after another – 1 minute, 2 minutes, 3 minutes and four minutes under the same part of the negative and write the times on the back.

Start the clock. Drop them all in the developer together and keep them moving, but don’t be too vigourous with the agitation.

Look for the faint image, -usually around two minutes.

Somewhere between three and a half and six minutes, depending on paper type, the black will begin to appear in the deepest shadow areas. You need to keep a close eye on it at this stage, as the black areas will get darker and creep up the tonal range. When you have the shadow tone you desire, remove the test and drop it in the stop bath. Do the same for each of the other test pieces. make a note of the times you removed the tests -this is known as the snatch point.

Examine the tests after they have been in the fix (Ilford Warmtone has a milky coating which is removed in the fix, making it difficult to accurately judge a proper black).

You will notice that the most contrasty one is the one with the shortest exposure and the longest development time (think of uprating film, -underexposure and overdevelopment mean more contrast). The one with the greatest exposure and shortest time will have the lowest contrast and may look rather ‘muddy’. One of the tests should have the tonality and contrast which is to your liking and this is your indicated time for the main print.

Method B

Mix up a tray of Ilford Multigrade developer in a second tray next to the Lith developer. Do a normal test strip in the usual way, eg; 5 second increments.

Develop this in the Multigrade developer and choose the exposure which gives you the first appearance of black in those areas which were clear on the negative.

Multiply this exposure by 10.

Give the print this extended time and develop in the Lith developer. The mids and highs should appear around two minutes and the snatch point will be between three and a half minutes and six minutes. If the developer is fresh and at 20?C, it won’t take too long, but as the solution ages, dev times can become really long. I did one the other night after printing for a few hours and it took half an hour!

Warmtone FB papers vary in their response to Lith developer and the 10x rule is only a guide, I know it works for the Kentmere papers mentioned above, and for Ilford Gallerie, but the Warmtone FB needs only about 5x extra exposure.

Whichever paper you decide to use, remember that the exposure can vary tremendously and still ‘work’ depending on the effect you are after. Overexposure lessens contrast and underexposure increases it, -but you may have very long dev times. Because of the excessive exposure needed compared to conventional printing, dense, overexposed or overprocessed negatives are to be avoided. Choose negs which are normal to thin.

Here are three prints, the first is Ilford Warmtone FB in Multigrade developer, the second is the same paper in Lith developer and the third is Ilford Gallerie in tired old Lith developer.

Consistency.

There are so many variables in Lith printing that it is very difficult to get two that look exactly alike. If you expose two or three pieces of paper and put them through one after the other you will have pretty similar prints, but if you were to do three prints over an hour they would each be different.

The developer oxidises quite quickly compared to other developers and the temperature can drop (a problem in the winter months in the UK). Lith developer is sensitive to temperature changes, so a heating device under the tray is a better method of control.

When the developer has oxidised it creates ‘pepper fogging’ which looks like exaggerated film grain.

Here you can see the difference between the left side which is the Kentmerel FB warmtone paper in old dev, displaying pepper fogging and the right side which is a dedicated lith paper in fresh chemicals;

I really enjoyed getting back into Lith printing and intend to do more. I’m going to shoot some winter landscapes with this printing method in mind.

    Interesting that you found Galerie worked, must give it a try.
    Ilford Warmtone FB is certainly subtle in lith, but really sings in 2nd-pass development. What’s more you only need a straight (slightly overexposed) print to start with and can work in room lighting! Just posted one I did yesterday.

    Do you know, I’m rather partial to a bit of lith too – only the long wait for the image to appear bugs me a bit.
