moon light can easily produce photographs. Although the light
levels might be too dim for us to see colour, with an extended
exposure the camera with either film or a CCD will record a surprising
amount of colour in the scene.
fact the results can be so good, that unless we consider the light
levels, how we frame the scene and the effect of the long exposure
the resulting image might seem deceptively as though it was taken
during the day.
|This image was taken in the moon light, and you can
see the light in the building in the background.
we look in the sky we can see the stars in the sky.
this image of the moon rise the image looks like an image that
might have been taken during daylight after sunrise.
in this image the exposure is very long (several minutes) - we clearly
see the stars and the clouds have moved during the exposure creating
a fascinating blurred motion.
small light with the green light in the lower right is not a UFO
- but is caused by light refraction from the direct rays of the
moon. This acts in exactly the same manner to photographing directly
into the sun.
||This exposure has been made in the moonlight - the tree in the foreground has been painted with light.
||In this detail from the image above the stars have recorded but also an air plane, seen on the left.
Extraneous lights will show up dramatically in image shot at this time of day.

following exposures are a guide which might be useful. Set your aperture

||1 Min 20 Sec
|7 days after/ before
||5 Min 30 Sec
||2 H.30 Mins
the dynamic form below for different aperture and film settings. The
exposure times are rough starting points, the subject surface (reflection),
ambient light and other factors will effect your exposure. When in doubt,
Failure is a problem that occurs with film's ability to evenly measure
light during long exposures. The characteristics of film is that during
an exposure it is initially very sensitive to light but as exposure
time increases the film's ability to record light is diminished. So
what a light meter may tell you should be a 1-minute exposure, for a
particular film that exposure may actually need to be 8-minutes.
Black and White
films are effective more by the reciprocity failure than color or slide
film. Check your film data sheet for it's characteristics and tables.
