Looking out of the window to see yet another morning of grey skies and dripping rain I decided to step back a few years and see what I was doing then. One of the most useful features of a digital photo collection is that it acts as a kind of visual diary. If you file your photographs by date taken, which I do, you can turn back to any particular day and instantly see where you were, and this often reminds you of what you were doing. So, five years ago this month I was - according to the image diary - staying in the Hotel Oriente in Barcelona. And the sun was shining. And it was warm. If I look back five years from now what will I see? Nothing, unless I venture out quickly and take my camera with me.
