Trawler

 - called Sea Gull and there is another partially hidden beyond. The river is the Great Ouse at King's Lynn.

Technically I find the white balance setting difficult around sundown, it seems that the white balance varies in different parts of the scene. The foreground mud came out distinctly blue so I desaturated the blues and cyans to restore a more realistic colour. The setting was auto, when I do these scenes manually a setting around 7000 - 8000 deg K seems to be about right. I shoot in RAW so the adjustment is easy unless there is variation across the image.

Advice welcome.
