By the light of the moon (27)



Requirement
Several images

Purpose
To work out the exposure as well as to to discover how the quality of moonlight differs from sunlight

Technical learning
  • Very different to photographing the sun or in sunlight as well as the moon itself
  • Anything less than a full moon almost certainly will produce an unsatisfactory result
  • Light intensity is c 20 stops less than in sunlight (e.g. an exposure of ISO 100, f16, 1/250 in sunlight would translate in to   - ISO 800 (3 stops) + f2.8 (4 stops) + x minutes at 32 seconds
  • Nevertheless, bracket to allow for fluctuation in light levels and inaccuracy in reciprocity (of duration and light intensity)
  • Although the human eye under moonlight sees strongly desaturated colours, the sensor will pick up the natural colours of the scene, creating an 'unreal' scene

Exercise instructions
  • Shoot a scene under moonlight, using a tripod and cable release
  • Bracket shutter speed to finesse  exposure
  • Examine the results
