David Brown’s digital print-making methods - written in the JAVA programming language - are complex, and each new print entails much experimentation and development. One technique involves using the tonal density in an initial image, using one of his photographs or paintings, to determine characteristics of drawn marks in the final print. The density, size, or colour of the marks may be made proportional to tonality in the initial image.
This image shows an extract from an original photograph of Norman Foster’s ‘Gherkin’ building in the City of London taken by David and an extract from the same area of the final print, in which the density of drawn marks (all coloured white) plotted on a black background is proportional to the tonality in the original photograph. http://bit.ly/GG_Gherkin
