Processing

This mainly needed "cropping", "levels" and "curves" to to improve the tonal range, and "colour balance" and "hue and saturation" to improve the colour balance. The antenae were emphasised after selection with "colour range", using "brightness / contrast". Then the web version was sharpened using "unsharp mask". The parameters were: amount: 300%; radius: 0.4 for the 700-pixel version, 0.3 for the 500-pixel version; threshold 5.
