Contact prints why?

Contact sheets
The humble contact print is a very powerful tool when creating an enlarged photograph. It passes on a wealth of information in its imperfect way. It is not just a positive record (proof) of all the images on the film but a starting point for the perfect print.

Not everyone agrees that a contact print of your processed film is needed. Instead, they like to work straight from the negative. I do not have a problem with this approach except on a practical level you need a light source to view them. I use the contact print not only as a reference for all my negatives but as an indicator as to which images are going to be more of a challenge to print. It is not always possible to see this when looking at the negative.

Making a contact print using a sheet of
glass to keep the negatives flat and in
contact with the paper. 
It is not a case of one, (the negative) or the other, (the contact print) but both together. By using them in conjunction you have all the information you need about the image you are going to print leading to a more judicious use of your time in the darkroom and a greater likely hood of the first proof print being closer to what you had in mind as the final print. A couple of tweaks to the next print may fulfil your vision.

Contact printing does not require an enlarger or any special equipment. A darkened room, a frosted light bulb suspended from the ceiling and a sheet of glass to keep the negative[s] in contact with the paper and flat. Edward Weston used this simple method for his prints. During the timed exposure he would dodge the image where necessary. Once this time had elapsed, he would burn in where he thought it was needed. This method can be a bit uncertain, as you cannot always see where you need to make the adjustments unlike that of the image projected by the enlarger. A number of large format photographers still use contact printing as a way of making their final print from their negatives.

When contact printing I use my enlarger set to white light, with the lens fully open. The projected light is greater in size than the 8 x 10 paper I'm contact printing with. For 35mm film I use a contact frame and for 120 format and above a pane of glass with a ground edge, so I do not cut my fingers.

There are varying opinions on whether you should set white light, use grade one or your preferred printing grade. I have always used white light with multigrade and varitone papers and yes it works very well. You get a full range of tones.
The enlarged image shows that this negative
would enlarge without adjustment.


Remember a contact print in its simplest form is a work in progress not the finish article. I have found that some of my negatives print better with white light than they do graded. At one time I used to produce all my enlargements with white light and was very happy with the out come. With experience came sophistication and now I use graded and split graded printing methods to get the best out of the negative.


You should do what you feel is best creatively for your negatives and not let others dissuade you from that path.

Silverproof paper


This is the second run of budget priced paper marketed by Silverprint and has a matt finish. The first run was gloss. I have used the later and was impressed with the photographs it produced. With its grades being limited to two I was not put off.

I originally purchased the gloss paper for contact prints and didn't really take much notice of how well they were being produced until I obtained a 12 x 16 slottie (Nova paper processor. which was the dirtiest bit of kit I have ever purchased second hand, a story for another post). The silver proof paper was the largest sized paper I had on the shelf and I was  impatient to see how well this new piece of kit worked. I was surprised by the tonality of the paper which lead me to make a series of photographs. It is a shame it was a limited retail run. It will missed.

Then a second batch was announced on Matt paper, which is a finish I'm not a fan of, but I'm always happy to try something new. This will also be a limited retail run, so if matt is your preference get some boxes in while you can.

The paper is completely different from what I'm used to. It is difficult to tell which is the emulsion side in the darkroom but with a little practice, the back has a slight  fibre feel to it which takes a time to get the hang of. First impressions are good, the photographs remind me of the cover page to Black and White Photography magazine in the way it looks and feels but has a depth to it that ink cannot replicate. It also does not have that richness of tone you get with gloss papers. Having said that, I like the difference and  expressiveness  it gives to the pictures it produces.

The pictures that complement this post were developed in a warm tone developer from Ilford with the enlarger set at grade two, initially it was set  at  grade three but I found that the pictures had to much contrast. On hindsight it may have been better to use an un-toned developer, but then I was not planing to use the proof paper for a full print session. I got carried away after the first test prints and I'm pleased I did.
