2. File storage
The two main file storage types for a digital camera are JPEG and Raw.
JPEG is a compressed file format, which means that it takes up less space than others
therefore whilst using this file type a larger number of images can be stored on a
memory card or hardrive.
A RAW file is a newer image format, which remains uncompressed and contains
unprocessed or undeveloped data from the image sensor of either a digital camera or
scanner. Having this larger file type allows you to edit the photo with more detail.

3. ISO
• ISO is the camera sensitivity to incoming light.
Each ISO setting is doubled from the previous
one for example if you change the ISO rom
100 to 200 you will be doubling the camera’s
sensitivity and if you take it from 200 to 400 it
will double again. This carries on through the
ISO scale.
This photo shows the effect of changing the ISO
setting. You can see the change in the ISO by the
change in the all round brightness of the object
as the ISO is raised.

4. Shutter Speed
• Shutter speed is the amount of time the shutter is
open. Most people will use 1/60th of a second
because anything slower will mean the camera will
have to be on a tripod to insure it is kept still. Most
modern cameras now come with an image stabilizer
to assist with taking images at slower speeds without
a tripod.
• Shutter speed doubles with each setting E.g. 1/1500,
1/250, 1/125, 1/60, 1/30, 1/15, 1/8.
In this photo you can see the effect of a slow
shutter speed, using this slow shutter speed on a
moving object gives a ghost like effect to all the
moving objects shown in the photo.

5. Depth of field
• The depth of field determines which point the
camera will focus on. The camera is able to
focus on one point at a time so parts in front
or behind the focused point will become
blurred giving a sharp effect to the focused
area.
In this photo you can see the effect of the depth
of field with the middle of the being clear and
sharp whilst the rest is blurred and out of focus.

6. Aperture
• Put simply Aperture is the opening in the lens.
When the shutter release button is used a hole opens up which allows your cameras
image sensor capture the scene you are aiming the camera at. The Aperture setting
lets you set the size of the opening. The larger the opening the more light that gets in
– the smaller the opening the less light.
Aperture is measured in F-Stops or F/Numbers.
An example of F/Numbers are f/1.4, F/2, F/2.8, F/4, F/5.6, F/8 etc.
Moving from one F/Number to the next doubles (or halves when going down in
F/Numbers) the size of the opening in your lens (and the amount of light getting
through).
Aperture has a big impact on the Depth of field. Large aperture (the smaller
F/Numbers) will decrease the depth of field whilst a small aperture (larger F/Numbers)
will give you a larger depth of field.
You can see in this photo that a high F/Number
was used due to the leaf being given a sharp
effect whilst the background is being blurred.

7. Focusing
• The four primary focus modes are Automatic, Manual, continuous and One shot. These modes give you a
tremendous amount of flexibility to capture exactly what you want.
• Automatic mode does most of the work for you by automatically focusing on an object and using the cameras
capability's to try make great results and super sharp images but using the automatic mode won’t always get the
results you want so the other modes will help you capture the image you want as you want it.
• Continuous focusing mode is the most useful for keeping moving objects sharp within the viewfinder as you track
the object. As soon as you press the shutter release, the camera springs into action and begins to focus on the
object in the viewfinder. In continuous focus mode, the camera detects the subjects movements and refocuses
accordingly to keep the object sharp.
• One shot mode, in this mode when pressing down the shutter release halfway, the camera focuses on the object
just once so there is no need for continuous adjustment. This mode is ideal for still objects and saves battery
power. However this mode isn’t as useful when trying to capture an object that is changing positions. This mode is
good for still shots such as family photos or wedding photos.
• Manual mode, manually focusing the camera can become the barrier between good and great photography.
Achieving perfect focus requires using the distance measurements on the lens barrel and can also require you to
physically measure the distance between you and the object to get an accurate setting. Professional
photographers usually use manual mode to shoot products this way and so do fine art photographers who are
using medium format cameras. Using manual mode will give you the most accurate focus point. Using this mode
requires you to use you internal sense of sharpness and know the critical focus zone that you have at the specified
aperture. Manual focus is important when you focus on a non-traditional subject, for example a subject that is in
the background when the foreground is busy and dominating.

10. Photos used in media
A photograph was used in this newspaper because it can show
the sadistic nature and lack of remorse of the killer after
committed his crime and it also shows the sadness of the
victims and their family's which gets the reader to sympathize
with the victims and their family's. Images are commonly used
in news articles to give more detail to the story and lets the
reader see what happened during or in the aftermath of the
subject of the article.
This promotional poster for the movie Grave Encounters was
shows with the actors posing in a dark tunnel to give mystery as
of why they are down there and what could be with them. Above
the actors shows a picture of an asylum with a filter used to
make the image look old and gives a tea stained effect to the
image. Using images in movie posters gives the viewer a chance
to get a glimpse of what the film will be about.
