©Paul Edwards 2011
Taken in the afternoon on 13th January 2011 at NGR SN7798844716, alongside the Nant (stream) y Bai, which flows past the waste dumps from the abandoned Nant y Mwyn lead mine. Unsurprisingly, this stream is contaminated with lead and other metals that are present in the mine waste. Canon EOS 40D, Canon EF-S 17-85mm lens at 26mm, hand-held. Exposure F8 at 1/50 secs. Original image in Raw format.
