2. There is not distinctive relocation of where double exposures initially came from, it is believed that it had been
discovered as part of early photographic experimentation In the early days these types of images would have been
created in a darkroom, with taking two images and superimposing them onto paper which would be light sensitive,
therefore transferring one image to another.
With this type of manual control several types of effects using this method could be achieved, simply but the way the
paper is layer and the areas of which the light hits. In today’s modern era, multiple exposure photography is used in
many forms of media – as a way of doubling a subject and combining them into one image. Most popularly seen in
sports shots, landscape and portrait photography.
3. Multiple exposure is a combination of two or more
separate images merged together to create one picture.
There are two methods to creating this type of
photograph, both internally and externally of the camera.
To manually achieve this type of shot “in-camera”, the
images are made by exposing a single frame twice. The
first shot needs to be the background and blown out of
every silhouette or shadow – so preferably the sky or a
bright background. Achieving the technique also comes
down to shutter speed, whatever the meter reading of the
subject is should equal to the shutter speed and the
exposure combined to create the shot. Most SLR cameras
now come with a multiple exposure setting, composition is
key to creating and equally lined up shot and also
incredibly bright natural or artificial lighting to work with
the exposure.
Out of camera – in Photoshop, this effect can be easily
created by layering separate images on top of each other
and lowing the opacity so that it covers the subject’s face
but their features still remain distinctive. Working in black
and white is the easiest method for multiple exposure but
often with quick shutter speeds can be achieved in
coloure.g sports shots, moving images.
4. The Harris Shutter method is effectively a strip device
made up of three colour filters. It was originally invented
by Robert. S Harris at Kodak, his method was creating
colour images with the inclusion of primary coloured
layers exposures within this shot. To achieve these types of
images the camera needs to be kept steady whilst
movement is occurring e.g. people, cars – whilst taking
three exposures with red, green and blur filters.
It is a more unique twist on the multiple-exposure method
but with the introduction of change filters through the
lens whilst the shot is been taken. When this effect was
first discovered it was traditionally achieved by using three
filters in front of a still camera that consisted of coloured
gels and two opaque segments. In today’s modern era,
iPhone and photographic apps have been created that
allows the effect to be copied more quickly and more
effectively in one shot rather than several.
It is also possible to manipulated and change current
photographs using Photoshop by experimenting with the
RGB channel of each layer of an image or three images
stacked.
