Fred Kerr is a photographer whose lifelong interest in Edinburgh’s transport began during the 1950s as he sampled the dramatic changeover from tram to bus operation and noted the variety of vehicles bought to accomplish this. He moved from Edinburgh shortly before the last trams were withdrawn but retained his transport interest during frequent visits to relatives. Following his move to digital photography he began photographing the local transport in 2011 when he decided to record the fleet changes as the company committed to achieve zero carbon emissions by 2030 and he continues to take an interest in the changes as they take place.
