This gallery contains examples of my experimentation with cyanotype process. Images made mainly from large format film negatives, also incorporating various objects as photogram elements. Beyond the basic cyan colour, images may be toned with coffee, tea, wine tannin, and other substances. ****All are digital scans from original prints.

If you do not ‘bleach’ out the blue cyan, before toning, the blue is tinted by the tea/tannin. Also the base colour of the paper is tinted* Tea tends to make cyan blue more muted like faded blue jeans, with white paper becoming a beige tone. Wine tannin will tint cyan blue to a deep purple and stain paper base a pale pink.
is another contact printing process, using regular silver gelatin photographic papers. In this case regular photographic enlarging paper is sandwiched in contact with objects or film and exposed in full sun for a length of time. Then the finished image is ‘fixed’ in photographic fixer chemistry and may be toned. Botanical specimens work best, because the induce formation of penumbra and regional tonal differences not produced by other media. Surprising colours are obtained from black and white photographic enlarging papers!
