I love this Margaret Watkins image of men loading or unloading a vessel in the old Queen's Dock, in Glasgow.

Good too to see the Finnieston Crane - properly called the "Stobcross Crane" or "Clyde Navigation Trustees crane #7".

I love how Watkins has used the huge door to the quayside shed as a framing device, helping to emphasize the light and shade.

Canadian-born Watkins was one of the first female advertising photographers on New York's Madison Avenue, but fled to Scotland in 1928 after becoming involved in a scandalous love affair with one of her married colleagues.

From her new, Scottish base, Watkins, camera in hand, travelled the world, taking remarkable photographs of pre-Second World War war France, Germany and Soviet Russia.

Then, one day, for whatever reason, she put her camera down, packed away all her prints and negatives, and never spoke of her work again.

Before she died, Watkins handed over a sealed chest to her Glasgow neighbour and executor of her will, Joe Mulholland, giving him strict instructions to not open it until after she died.

After her death, in 1969, Joe opened the chest, and found her treasure - her complete photographic archive.

Since then, Joe has organised a number of exhibitions of Watkins' work, both at his Hidden Lane Gallery, in Argyle Street, and in North America.

In 2013, Canada honoured its 'lost' daughter, with the Canadian Post Office issuing a stamp featuring Watkins' still life photograph, The Kitchen Sink.

You can view a selection of her remarkable work at the Hidden Lane Gallery, 1081 Argyle Street, Finnieston.
