Solway Firth

 Canon 5DMkll, EF 24-70 f/2.8, 13sec, f/16, 10 stop ND filter.

Not sure about the processing on this one. Is the vignette adding or subtracting?
The main feature is of course that sky! It was amazing

Panorama of two files blended in CS5 then converted to black and white. Separate processing in CS5 for sky and land. Final processing in Silver Efex Pro including adding vignette.
