In any photographic manual you'll come across the strickingly clear images of a landscape, apparently taken by night, in the light of a full moon. The secret behind this magical vision of "darkness at noon" is usually revealed in the accompanying text. Readers of this book will not be well versed about the sensitivity of my retina - I can hardly sense it myself. So they will not be able to check what is said against a photographic plate to discover at precisely what time each of my "pictures" was taken. What this means is that if I present you with an image and say, for instance, that it was taken at night, you can either believe me, or not; it matters little to me, since if you don't happen to know the scene I've "photographed" in my notes, it will be hard for you to find an alternative to the truth I'm about to tell. But I'll leave you now, with myself, the man I used to be... __ 1951, Ernesto Guevara - Notas de Viaje (Travel Notes or Motorcycle Diaries)
