Thoughts of a Night Sea presents Garry Fabian Miller's most recent series of photographic works, although the term photography describes them in only the broadest sense. Since 1985 Garry Fabian Miller has worked without camera or film, using the first principles of photography to explore the alchemical action of light and chemicals on paper. His artistic language - like that of other cameraless photographers such as Adam Fuss and Susan Derges - is essentially abstract and his raw material is light itself. Thoughts of a Night Sea marks a return to the emotional and physical territory of Fabian Miller's celebrated early series 'The Sea Horizon', although unlike those camera-based images the horizon here is not a real one. It is a marriage of sea and sky born in his imagination and conjured in the darkroom: a subtly changing sequence that looks back to the seascapes of J.M.W. Turner and forward to the lightscapes of James Turrell. This powerful and poetic group of pictures has prompted Greenlaw's meditations on Fabian Miller's imaginary world, and their collaboration has given rise to a book that is equally a celebration of Fabian Miller's work and an artwork in itself.
