Digital photography opens new realms for image cre-
ation at night, along with new problems and pitfalls.
Digital sensors don’t see the night the way our human
eyes do (or the way film did, for that matter).
Your digital sensor doesn’t really care that there isn’t
very much light out there in the night. You may be
stumbling around in the dark trying not to fall off of
a cliff (the chief occupational risk to night photogra
-
p
hers), but provided you expose your camera so that
the sensor gets plenty of light, your photos won’t por-
t
ray the scene as dark at all.
The fly in this ointment is that exposing a night scene
properly means using a high ISO, or a very long shut-
t
er speed (sometimes in minutes), or both, resulting
in substantial levels of noise (see Chapter 4 for more
about noise, and pages 162–163 for information about
noise reduction in the digital darkroom).
Your digital sensor will be able to pick up and record
light you can barely see, particularly after sunset. For
example, even after the glow of sunset has faded from a
cliff to human eyes, it is often still colorful and vibrant
to a digital camera, provided the photo is properly ex

posed and post-processed.
Sometimes the beautiful after effects of sunset are in-

and don’t emerge until the photo is p
