One day my great grandchildren will go up into the loft and find a batch of prints that've been sitting there for 50 years. Upon closer inspection they may recognise what they see. They could also find hard drives except of course in 50 years they won't have the hundred divergent cables and plugs Apple introduces every 3 months. All you need is light to unlock the potential of film. Lastly, a photograph, a print is a gift, the space in which that gift is created is the darkroom, a powerful space where the gifts are not mass produced but crafted into being.
