2. • A multiple exposure is when two or more images are
combined together to create one single image.
Although it looks complicated, as long as it is
planned well, it is quite easy to produce. There are
many different reasons why people choose this
technique such as trying to create a ghostly effect, a
mirrored effect, or simply to merge a moon into a
sky. More complicated exposures, like the ones to
the left, are done for a fine art purpose to create
world that cannot be possible.
• Multiple exposures first started out as an accident
when using a film camera but now-a-days artists use
Photoshop to create these images a lot easier and
for a purpose.
To create a double exposure with a film camera you
have to take a picture, then hold the rewind button,
advance the shutter, release the rewind button and
take the next picture. Then they will be developed
together.
Most people create double exposures digitally now.
This consists of you taking your images, uploading
them onto Photoshop and layering them over the
top of each other and adjusting the opacity.
• You will need access to Photoshop and a digital
camera and a tripod to create multiple exposures.

3. • High speed photography records fast moving objects
that are normally invisible to the human eye.
• Scientists use high speed photography to study
physical movement and gravitational effects. The
military uses this technique to look at missile and
rocket accuracy and to record what is happening at
the core of a nuclear explosion. It is also used in
sports photography such as tennis, biking, racing and
horse racing. It is popular for artists too and this
work would be shown in galleries.
• Firstly the aperture and shutter speed needs to be
altered. The shutter speed needs to be as short as
possible (1/800 second), and the aperture needs to
be large (F14), this will help capture the image
quickly and still have enough light to be captured. It
is crucial that you have a totally dark room. If there is
any light in the room, there will be some exposure
on the frame which can appear as blur in the final
image. But a high flash will need to be used to light
up the object when the shutter shuts.
• You will need camera with manual controls and a
flash available. You will also need a tripod and if you
need to edit your image after you will need access
to Photoshop. Post production isn’t usually common
with high speed photography but colours could be
brightened and sharpened.

4. • The Harris Shutter effect is a strip device with
three colour filters layered over the top of each
other which was invented by Robert S. Harris.
• The effect was originally created by re-exposing
the same piece of film 3 times through 3
different colored filters while keeping the camera
steady, but when Photoshop came along the
whole process became a lot easier. All you have
to do is take 3 photos of a scene that has a small
amount of movement in it and an object that
remains constant. The all you have to do is layer
each image and select ‘Color Balance’ and boost
the colours to one colour for each single image.
Once they are layered over the top of each other
you will need to blend them together, you can
either do it by opacity or addition.
• This is a great technique for moving images. It
gives it a trippy/ 3D feel to the final image.
