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

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.
