He originally trained and worked as a sculptor, constructing pieces from steel, wood and cement fondu.
In 1998, he moved to Irvine, Ayrshire, in Scotland and, though registered blind, had enough confidence in the new paintings and drawings he created to once again start exhibiting them.
During this time his work has developed in two different styles: organised scribbles that form his drawings, and the bolder, broad marks in oil or acrylic paintings.
Over the last few years he has combined the scribbled pastel line with the painted acrylic marks, stating that he is "trying to capture a little of how I experience these wonderful wild places".
In 2009, Salmon won the Jolomo Award[4] for Scottish landscape painting[5] and was interviewed by The Scotsman,[6] one of Scotland's top broadsheet newspapers.
