My negatives are cut into strips of six, and, over the years, the individual strips have been moved so many times, they no longer have a logical sequence. Whilst each shot within the six is, obviously, related in time and place to those adjacent, the same cannot be said for the 700 or so individual strips. A few months ago, I scanned a strip of negatives that started with a photograph of Halifax Town Hall been stone-cleaned. The time on the Town Hall clock on that photograph was five minutes top eight. Today, I came across another strip of negatives, the last of which, is another photograph of the town hall being stone cleaned. This time, the time of the town hall clock is six minutes to eight. We have a sequence!
