Agfacontour Professional was a special emulsion sheet film which after exposure and development in the Agfacontour developer produced direct equidensities. Agfacontour was introduced in 1970 by Agfa-Gevaert to enable producing equidensities by a direct, one developing step process; until equidensities had to be obtained using one of the following techniques. The most popular method to acquire equidensities was the One-Film technique, better known as Sabattier effect. Another techniques making tonal extractions on high-contrast film was called Two-Film technique. From the negative 3-5 different exposures were made on 3-5 ultra high-contrast films; these 3-5 positives were copied on again ultra high-contrast films to obtain negatives. One positive and a different negative were sandwiched together in register to obtain one equidensity. Using the same shuffling, the other positives were combined with the negatives to make in total 2-4 sandwiches of 2-4 equidensities series. Although there are other techniques such as Scattered-light technique or Electronic technique, these are less important for obtaining equidensities series.
Each of these techniques had its drawbacks of which reproducibility and extensive work involvement were undoubtedly the most important ones. Therefore the researchers at Agfa-Gevaert set up a workgroup to develop a film that enables the use of equidensitometry with the following, principal evaluation methods of an information-carrier A Black and white extract of a controllable range of densities Breakdown in separate density ranges which could be created in a manageable manner by colorizing or using Halftone screens Distance measurement of similar densities Information clarification in the presence of chaotic density distribution and density gradientsThe Agfacontour film contained two special emulsions with each different spectral sensitivity. By using color filters during the exposure one could narrow or widen the width of the equidensity. By varying the exposure one could change the density in the image that showed on Agfacontour as equidensity. Although the material exhibited low sensitivity the results were reproducible and second order equidensities were sharp and clear, something that with pseudo-solarization was impossible to achieve without special procedures.
The Gamma of the material was high, power of resolution was 40 lines/mmSince the introduction of Photo editing software, altering curves into U-curves produces equidensities. For the image at the right a darkroom process was used that encompassed the production a serie of equidensities of the negative, enlarged on Agfacontour Professional sheetfilm; each sheet was copied onto lith film and developed in lith developer. Each copy was developed in a chromogenic developer. All colored lith films were put together in register and a positive print on color paper was made.
