0679 Flotsam on a twilit tide, Golden Bay. 8.30pm, 5 March 2015

In photography the golden hour before sunset is followed by the blue hour of developing darkness. The blue cast can be mitigated with a light balance setting above “Direct sunlight”, which in degrees Kelvin measures about 5500. On the Nikon D700 you can choose to a maximum of 10,000 deg. Conversely, the blue cast can be exaggerated with a tungsten or sodium colour balance – each below 4,000 deg K – especially useful if your subject is lit by old style torch, headlight or house lights. However the reflected moonlight shown here has an unmodified light balance, for a simple composition. Selected by my daughters, each independently.

239. From our balcony, after midnight

From our balcony, after midnight. 12.04 am, 6 May 2012

[Only the camera can express] the full majesty of the moment. –  Paul Leopold Rosenfeld

Looking down on the tops of the persimmon. You can only do this on a very still night, as the slightest breeze blurs the detail. However, to get a really creative blur, you need a gusty evening – nothing in-between is very satisfying. An aperture of f16 is the smallest on my telephoto lens; at close range the depth of field is minimal even at this setting. The light is a mixture of moonlight and ambient city light. The cool tones of the background roof show mainly moonlight (it is leeward of city light), while the warmer leafage shows it was more exposed to the street lighting.

173. Night riot in green

Night riot in green. 12.39 am, 11 November 2011

I confess that the head gardener has long asked for a moonlight photo of these louts, here at home. On the wrong side of a trellis, the artichokes are shaded from the full moon until after midnight; they’re also exposed to the sickly orange of streetlights.

To fix the first problem I togged up after midnight, for the second I lowered the light balance further; on the D700 sodium is covered under a fluorescent option. Better still would have been my wife screening the plant with her person – but no, she was warmly tucked up in bed.
