After experimenting with ferric chloride as an etching mordant on aluminium and not getting very good results, l returned to etching in a copper sulphate saline solution.
The resultant image is a viewpoint in the centre of Birmingham taking in modern apartment building along Charlotte St and the iconic BT Tower. The canal lock gate and the elegant parabola forms of the footbridge made this an attractive subject for me.

This image was successful in being accepted for inclusion in the RBSA Prize exhibition currently running.
