First place, Abstract Views. “This image of three allium heads was created using a technique known as wet cyanotype. Two chemicals, ferric ammonium citrate and potassium ferricyanide, are mixed together to create a photosensitive solution which is painted on to the surface of watercolour paper and left to dry. This process needs to be conducted away from UV light, and once dry the paper must be kept in a light-proof bag until it is used”. (Photo by Jill Welham/The Guardian)
