Reciprocity failure – not!

Been shooting in some old dark quarries today, no sunshine. Had to use slow shutter speeds, sometimes less than 1 second but the really great thing about digital cameras is there is no reciprocity failure. No need to make the calculations and then bracket exposure to be sure. Made life a lot easier but would still like to use 5×4 colour neg if I could afford the near £10 a shot for film and processing.
