A masking frame for photograms

The challenge of accurate alignment of objects on a sheet of colour photographic paper and masking areas for multiple different exposures in total darkness, demands the assistance of a suitable tool for the job. Commercially available darkroom masking frames are designed perfectly to hold a single sheet of paper flat but have no mechanism for ensuring the precise location of three dimensional objects or re-positioning them for further exposures. I felt this called for a tray design, with shallow sides and removable blocks of different sizes to create the spacing for the commonly available colour print papers I use, 16 x 12 in., 12 x 9.5in and 10 x 8 in. The design I came up with used a sheet of MDF and strips of  10mm thick and 25mm (approximating to 1 inch) wide timber cut to several lengths and painted matt black to minimise reflections. The outer fixed strips have been fixed with adhesive to create a base with internal dimension of 16 x 12 inches. The inner removable strips vary in size from 6 to 12 inches in length, with one 12 inch strip halved lengthwise for the 9.5 inch paper.masking-frame-(2-of-2)One inch is more precisely 25.3mm and allowing for the thickness of two coats of paint (and my very limited woodworking skill-set), the jigsaw of pieces fits together reasonably efficiently. A few small gaps are inevitable however and stray narrow shafts of light should get through unpredictably frequently enough to leave room for serendipity to have an effect. The paintwork needs a few more days to harden and then it will be time to get back in the darkroom to find out how well it works.

Colour theory - Itten and Albers

Two of the most influential texts on colour theory were written in the 1960's by two men with similar backgrounds but very different approaches to the subject. Both by that stage had recently retired from distinguished teaching careers to concentrate on being working artists, Johannes Itten (1888-1967) having been Director of the Museum of Arts and Crafts in Zurich and Josef Albers (1888 -1976), Chair of The Department of  Design at the Yale University School of Art in Connecticut. Both men had strong connections with the Bauhaus School in Weimar Germany. Itten developed and ran the Preliminary Course which was compulsory for all first year students from its inception in 1919 until he fell out with Walter Gropius in 1923 and moved to Berlin to start his own school of design. He moved briefly to the Netherlands in 1938 before returning home to Switzerland later that year (Art Directory Gmbh, 2019). Having enrolled initially in 1920 Albers was the first Bauhaus student to join the teaching faculty as a Master in the glassmaking studio, at the time the school moved to Dessau in 1925. When the National Socialists came to power in Germany in 1933 and the Bauhaus finally closed, he and his wife were invited to establish the inaugural visual arts course at the Black Mountain College in North Carolina (albersfoundation.org, 2019). itten-(1-of-1)On first impression Art of Color : The subjective experience and objective rationale of color by Johannes Itten has the look and feel of a beautifully illustrated traditional large format textbook. The early chapters explain colour physics, with brief descriptions of the colour spectrum, the light forming wavelengths of  electromagnetic radiation  which are focused via the optical mechanism of the eye (cornea and lens) to be captured by the photosensitive cells in the retina (the sensor), then transmitted to the optical cortex of the brain to be perceived as a continually refreshed image. Subsequent chapters move on from these objective principles to his own theories (expanding on earlier work by Adolf Holzel with whom he had trained in Stuttgart), which explore how our subjective perception can be influenced by emotional and symbolic factors in combination with the visual interactions of complementary and contrasting colours (bauhaus100.com, 2019). "Color perception is the psycho-physiological reality as distinguished from the physio-chemical reality of color" (Itten, 1963). His explanations of the significance of these phenomena are illustrated by reference to a series of paintings ranging chronologically from eighth century religious paintings, through the work of the European old masters, to the abstract modern art of Klee (a fellow Master in the Bauhaus teaching faculty), Mondrian and Picasso. The book is worth reading for these comprehensive insightful explanations alone.The approach taken by Albers in the more modest looking Interaction of Color is that of a practical course manual for students in a colour theory classroom, presented as a series of exercises using swatches of coloured papers, designed to demonstrate rather than simply describe how interacting colours are perceived. The illustrations linked to each chapter are presented separately from the exercises, the aim being that students should first try to reproduce them for themselves, presumably as a more effective way of learning. Many of the exercises recreate apparent optical illusions (colour deceptions) but in doing so, provide rational explanations for complex phenomena and like Itten, demonstrating that "in visual perception there is a discrepancy between physical fact and psychic effect" (Albers, 1963). His demonstrations of the use of the effect of colour intensity (brightness) to show how an identical swatch of colour is perceived differently depending on the background it is placed against (page 8) and the phenomenon of the after image (page 22) are simple but remarkably effective.0405-2019-1238476173423294124199I am working my way through both of these books at present and am only just beginning to get to get to grips with the subject. The featured image below is my digital photograph of a step in a bathroom ceiling which is painted entirely white.color-interactions-(1-of-1)The colours have been produced through manipulation of the RAW file  in Adobe Photoshop Lightroom, simply by accentuating (albeit grossly) the existing colour casts in the image. The sunlit area is warm in tone, producing the primary colour yellow when enhanced, while the tone of the area in shadow is cool forming the complementary blue when accentuated. These casts are barely perceptible in the original  photograph and not normally 'seen' by the naked eye as, knowing that the paint is white, our brain 'corrects' this for us. Photographers working in colour, in trying to obtain colours which are true to life, usually correct these casts when they become apparent. This experiment for me suggests that in reality the colours are already there, which would mean that in striving to obtain tones which will be perceived as 'true', we may in fact be perpetrating a deception. Albers J (1963).

Colour darkroom printing

In looking for more imaginative ways of making photograms in the darkroom, I have been exploring the possibility of creating them in colour using 'C' Type papers and RA4 chemistry. As a result of the panchromatic nature of colour materials, the practicalities of colour printing are more complex than monochrome printing with silver gelatin processes. The papers need to be handled in total darkness (no safelight). They degrade quickly if not stored correctly and the chemistry also needs to be fresh. The processes  require higher temperatures for the chemicals which need to be tightly controlled, especially the colour developer (to plus or minus 0.5 degrees). Although black and white darkroom papers can produce interesting results even when many years out of date, after several completely unsuccessful  attempts to produce an image, I have learned the hard way that this does not work with expired colour chemicals or with colour papers which had been stored for several years. Having obtained a new box of Fujicolor Crystal Archive paper and Tetenal RA4 chemistry, I have finally managed to make some test prints which have strong bold colours and am hopefully about ready to start making some new images.colour-wheel-(1-of-1)Getting to this stage proved more challenging than initially expected and I found it difficult to think in terms of inverted colours as well as inverted tones. For example, correction for a yellow cast in a print, requires the addition of its' complementary colour i.e. blue (Fig 1. above). The colour produced on the print is however the inverse of colour of the light projected on it so confusingly, to correct a yellow cast it is necessary increase by filtration, the amount of yellow emitted by the light source (see Fig. 2 below). When researching this I realised with regret that I had thrown out all my basic "how to" photography books which at the time seemed redundant but would have contained all this information. I also discovered that in most of the current versions of these books available in the college library, the sections on colour printing in the darkroom have been largely replaced with information on digital imaging but I found a limited amount of what I needed in "Langford's Advanced Photography" (8th Edition).Colour-wheel-Langford-201902111--EditOut of the box, colour papers have a cyan coloured coating on the surface which acts as an anti-halation layer and presumably at least partially corrects for the orange mask present on the surface of most colour negative films. My plan is to attempt to make colour photograms and am not using negatives so the cyan coating produced a very strong reddish brown cast on my initial tests (Test print 1) and after experimentation  I found that much stronger yellow and magenta filtration than anticipated was needed to achieve anything close to neutral greys (bottom (R) image on Test print 7).Test print colour001Test print colour003Test print colour002In the process of reaching a reasonable approximation for the basic colour filtration required for neutral tones, I have discovered that it will be possible to produce a wide range of both bold and subtle colours which potentially offer exciting possibilities for the work I am hoping to create. This is will undoubtedly involve more experimentation and although the element of serendipity is often useful in producing photograms, in addition to fine tuning the colours utilised, I will need to develop a technique for getting the objects used into the optimum position on the paper in complete darkness before making the exposure. The image below, my first crude attempt to produce a colour photogram, shows some of the visual potential of the technique, while demonstrating the need to tackle the issue of alignment of the objects on the paper.Photogram colour plastic001 Reference: Langford M and Bilissi E,  'Negative/Positive Colour Printing' In: Langford's Advanced Photography (8th Edition) pp 296-301.
