Exercise 4.3 preliminary – transition time

My main response to exercise 4.3 is a set of night-time images, taken in central London on 20 September. The images in this posting are a subset taken over a 10 minute period around sunset, between 7:01pm and 7:10. Sunset was 7:03, not that one would notice, given the heavy overcast. What is noticeable is the rapid change of light levels and the changing relationship between the intensity of the artificial light and the lightness of the sky.

Images were made with a Pentax K-1 and 24-70mm f/2.8 lens, used in manual exposure mode. There was minor tweaking in Lightroom, to adjust overall contrast rather than exposure.

All images were shot in RAW mode, deferring decisions on colour temperature until post-production. All images were set to ‘daylight’ (5500K) colour balance to enable a proper assessment of colour changes.

The interesting point is that, with the exception of the very bright ‘stage lighting’ floodlights on the SNOG bus, the artificial lights are insignificant in relation to the overall daylight levels. The first of the images used in Exercise 4.3 was taken at 7:20pm, 17 minutes after sunset, by which time the scene had darkened noticeably and it is the artificial lighting that dominates.
