Twenty years of work by Shipley -based photographer Tim Smith will go on show in an Aire Valley Waterways exhibition.

Photographs charting the development of the River Aire and the Leeds and Liverpool Canal, as well as images capturing the transition from traditional factories, manufacturing textile looms and spinning silk to high-tech businesses, will be on display at Central Hall, Keighley , from Friday until August 31.

The exhibition is open from 8.30am to 4pm Monday to Friday and 9am-2pm on Saturdays.
