Aperture
The aperture is the opening that lets light in and
closes light out.
DOP- Depth of Field is the distance between the
nearest and farthest objects in a scene that appear
acceptably sharp in an image.
Shutter Speed
The shutter speed is what controls what’s involved in
the picture and can allow movement, here is a
picture show the shutter speed at a slow setting.
Shutter Speed is the measurement of time the
shutter is open for. It varies from f2 – f5.6 - f16 and
higher.
Focussing
Focussing
A real image is formed by light moving through a
convex lens. The nature of the real image varies
depending on how the light travels through the lens.
There is two major factors of this: The angle of the
light beam’s entry into the lens and the structure of
the lens. The entry of light changes depending of
how close or faraway from the object you are.
ISO
ISO is a setting on the camera that is about the
sensitivity to light and how its measured, and helps
understand when you should increase the ISO
setting.
File Formats
JPEG – Joint Photographic Experts Group. This is the right format for those photo images which must be very small files, for example, websites or email. JPEG is usually used for digital camera memory cards.
RAW – A camera raw image file contains minimally processed data from the image senor of either a digital camera, image scanner, or motion picture film scanner.

Camera ComponentsThe components of a camera are the lens, shutter, aperture, sensor and the
flash.
The sensor transforms light from the lens to digital information which is then stored on a memory
card. The most popular measure for the Sensor Chip is Pixels Per Inch and range from 1.3-22
Mega pixels. The more pixels the larger the digital image can be enlarged and stay clear and
sharp.
Most digital cameras come with a built in flash. These are useful for close-ups in terms of providing
lighting up to around 4 metres. These can also be used to fill shadows in sunlight. One of the main
problems with using a flash is red eye. This is when pupils appear red in an image. This is caused
by light reflecting off the retinas in our eyes. Most digital cameras allow you to change the settings
of the flash e.g. red-eye reduction
Whether you use a mobile phone, compact digital camera or a digital SLR you will probably be
familiar with digital cameras and how to take pictures. Below is a brief overview of the
component parts of a digital camera.
All digital cameras have a lens. The lens is usually made of several pieces of glass and other
elements. The lens focuses the image onto the digital sensor, where it is captured for storage.
The shutter on a digital camera is a component that opens and closes to control the length of
exposure. The exposure is the length of time light falls on to the sensor. The shutter opening time
affects the image exposure and how motion is shown.
Every camera has an aperture. Sometimes fixed but usually adjustable, the aperture is a hole
that varies in size to control the amount of light falling on the sensor. Aperture is measured in f-
stops: a higher number represents a smaller amount of light.
With a high aperture the shutter can stay open longer (as less light gets to the sensor).
To advertise Demi’s new cd DEMI it was
advertised on music channels, and normal TV
channels so anyone who likes her and her music
could see she has a new album out and when to
buy it and where from.
This product is aimed at fans of Demi Lovato.
The photos and video footage they used to
advertise this product are useful because they
draw you in, they are informative and make you
want the CD.
Fifty Shades Of Grey is already a world-
wide phenomenon and the film isn’t even
out yet. It has had a lot of advertising
through, print publishing, adverts on
Youtube, and the main advertisement is
the book itself.
The photo used on the cover on the book
is both sensible to be on the shelf
because its not explicit but it also
describes the character Christian Grey
very well because the colour of the photo
is dark and different shades of grey. It is
also an image of a tie showing he is well
presented in himself and serious at the
same time. By seeing just this image its
leaning to want to know more about him
and the story.
