One of the most
important aspects of creating a photograph, is light. Light has been
at the center of my work for a long time as a photographer and gardener
it is impossible to escape. It fascinates me and I have used it and
made reference to it and many different projects from traditional
photography to - photographic
journeys that follow the sun - to installation
work with projectors and also for projects where I grew
images on the leaves of plants. Besides the fact that, without
any light it would be impossible to take images at all, light is the
ingredient that is used to define the subject- aspects can be revealed
or concealed. There are two distinct way is that we can apply light
when taking photographs. One is to use light in a natural environment
– this means visualizing how it falls on the subject –
the subtleties of light, shadow colour etc, and understanding how
it will reproduce in the image. To gain the best effect it might mean
waiting until the light changes. The other is to use light in a tightly controlled situation like a
studio, where the environment is totally dark and we had in the lights
we decide to use.
Of course there
are combinations where we might use some controlled lighting outdoors.
So what is Light?
is actually electromagnetic radiation that the human
eye can see.
radiation can be considered in terms of a continuous
spectrum which includes light, radio waves, radar
x-rays, gamma rays and other forms of radiant energy.
What distinguishes each one from the other is the
wave length. As the distance from one crest to the
next, which can be anywhere from many meters to less
than a billionth of a meter, varies the quality of
radiation alters. Only visible wavelengths are
defined as light, and all others are simply termed radiation. In terms
of light we see these variations as different colours.
