This is an image I shot on Sable Island. It was taken at dusk, I had the camera on a tripod with my 100-300mm zoom lens and the camera set at: 10 seconds at f4.0, 250mm, ISO100, RAW.
In CameraRAW I optimised the image by adjusting the levels and curves and so on. This is a technique that I haven't used much before.
Not sure about the quality of the JPEG however.
