Multiple exposure photography involves combining two or more separate exposures into one image. It has been used since the early days of photography as an experimental technique. The traditional method involves not rewinding film between exposures to capture ghost-like overlapping images on a single negative or print. Modern software like Photoshop allows creating complex multiple exposure composites digitally by layering and adjusting individual photos. 3D photography creates an illusion of depth by processing two offset images, one in red and one in cyan, that can be viewed through 3D glasses. The basic process involves duplicating a background layer in Photoshop, shifting one layer slightly left and the other slightly right, then adjusting color levels to separate the images for the 3D

3. Multiple Exposures
Multiple Exposure- The filming of more than one scene in a single frame (Collins English
Dictionary)
The repeated exposure of a photographic plate or film to light, often producing ghost images
(Oxford Dictionary)
Multiple exposure is a photography technique of combining two or more separate exposures
into one.
This technique is involved with fine art photography as well as being involved with highly
advanced commercial photography. It is used in commercial architectural photography and high
end interior design.
History of Multiple Exposure. Since photography came about 200 years ago, artists and
photographers have tried to advance the images further to what is not seen my the ordinary
person.
Multiple exposure was created through experimenting with exposures.
Before the use of advanced technology , this technique was first created using a dark room.
The idea of a dark room being that no light at all can come in the way of a piece of art. Work
not being exposed will look very unusual to the normal piece of Art

4. Many photographers still spend the time to make the original multiple exposure copies as they believe it creates a
better outcome rather than editing images on Photoshop.
The normal process involves having two negatives and photographic paper. When looking at multiple exposures, the
technique involves not rewinding the last exposure taken.
This technique takes time and patience, whereas since the development of cameras and software such as Photoshop
the process is so much easier. However, It has taken some of the originality from the designs.
Multiple exposure is now a very popular method of Experimental photography and has started to feature in many
forms of media. Magazines and Newspapers do occasionally offer a strange look on an image as well being seen in
galleries across the world.
The new way to develop the two images is in Photoshop, this modern way is a lot quicker due to being able to see the
images as soon as they are imported.
This involves having the two images on separate layers and turning the opacity down on the image in front so the
other photograph is visible.
Using the Polygon tool to rotoscope the part of the image you do not want can be very useful. Also, duplicating a layer
or image can be a very good way to manipulate the exposure.
Being able to change the light on an image in Photoshop has become a very important part to Multiple exposure
Photography. This helps bring out two images but the light being artificial and placed in an area where it can be looked
at differently.

5. Redscale
technique is
used to make
the cemetery
look similar to
that of the
‘Gates of hell’.
The vanishing point and having leading
lines makes the numbers stand out more.
Not only can you see Aisles in the sky but
a face is featured at the top left of the
image.
Making the clouds such a light shade of
green makes the image look very
particular. Also the merging of both
shapes, numbers, lines and a face makes
the person looking at it think.
The colours
on the zebra
match the
lines on the
piano which
makes this
piece very
interesting to
look at.
The colour adjustment tool and
the levels in particular is a great
way to make this image look
strange to look at.

6. 3D Photography
The viewing of objects as three-dimensional, the
technique of making or using stereoscopes and
stereoscopic slides.
Stereoscopy is the technique for creating or enhancing
the illusion of depth in an image by means of stereopsis
for binocular vision.
3D photography is made using Adobe Photoshop. This is
to process an image which can then later be viewed with
3D glasses.
It is created by using two layers in Photoshop. Two layers
include one cyan coloured image and one red image.
One of these has to be moved away from the other at
both the left and right hand side. For example, the Cyan
being underneath will be moved a couple of touches to
the right and then the red layer would have to be moved
a couple of touches to the left.

7. Normally, a 3D photograph is made from
two photographs taken from slightly
different positions.
What you will need and how to do it.
You will need to purchase 3D Glasses. (Approx Price £5.99)
This is because without the glasses you cannot view both the cyan and red colours
when in Photoshop.
The process- Firstly you need to open up Adobe Photoshop (If you do not have it you
can get a free trial for 3 months)
You then need to open up a document (International Paper), after this you need to
select a background.
This background layer should be coloured in red. After this, click on the layer, duplicate
it and then change to cyan (This procedure can be either colour first)
Open up an image in Photoshop (Can be done through the place button on the tool
bar) the image has to have something in front of it or the process wont work.
Now go into Levels (This can be found by pressing CTRL + L)
On the cyan one, select a white slider, and on the red one select a green one. Now in
the channels box change the white into a blue colour.
You then need to move the layers, move the cyan left of the red and the red right of
the cyan.
Once you are doing this procedure you need to place your glasses on. After you have
moved the object to how you want it, you should then crop it as you have moved the
layers.
It is a very complex technique but when it comes right it can create a very good effect.
This technique is often used in many films now.
Many people like the effect and is very popular because it looks as if you are there
with that person or subject you are looking at.
