Here are 4 shots out of 140, if you would cast your eyes over them for me. The day was very bleak and nowhere as bright as the images show. Heavy post processing I am afraid and when enlarged the noise is atrocious. However, the name of the game was sharpness.
I have taken your suggestions on board and tried them out but only on an empty and drab landscape.
I shall try the 5k run again and I am looking to do a shoot at our local main line railway station. Nothing to compare with your Big-Boy but plenty of DMU's and Euro stock. Enjoy your travels.
PS I have upgraded to Silver membership following your helpful suggestions...tell your boss he is not paying you enough!
