Picture 5

This is the original image of the crawley library. The image below is the edited version.


With this image i used another filter to create a blured effect. The actual effect i used was motion blur. This makes the image look as if it has some sort of movement in it, or as if it had been taking by a moving car. Compared to the original copy the colours are a lot duller than in the original. You could use this picture in a piece about road traffic or even speeding in the local area.

Picture 4

This is the original image of a sea gull in a park. The image below is the edited image.


With this image i used a filter to change the picture. I went into the texture tab and used the texturizer to give the effect that the photo is now on a canvas. Compared to the original copy the picture also looks a lot greener and more fuller. Its also made the picture look newer compared with the original because the original copy has hints of brown in it. With this photo you could use it too write a story on a famous painter who lives in the area.

Picture 3

This is the original version of the picture. The one below is the edited version.


With this picture i played with the hue/saturation and made everything seem pinker. This would be classed as an un-ethical picture as your changing how things actually are. When started to edit the picture i found that i could change the whole picture so everything was a different colour however i found that the pink stood out the best because it was the most unusual. You could'nt use this picture in a journalistic piece of work because its portraying something its not. (It's unethical.)

Picture 2


This is the original picture of one of the college courtyards. The picture below is the edited version.


With this picture i edited the colour balance making the red higher and the magenta and yellow lower. Compared to the orginal the photo now looks as if it has been taken at either dusk or dawn rather than just in the middle of the day. When i edited the picture i wanted to make the image look as if it was in an abandoned by playing the colour balances. From the final piece it has a redish tint which could be used in a story about a crime or murder.

Picture 1

This is the orignal image of a women walking through the memorial gardens. The one below is the edited copy.


I decided to adjust the contrast and exposure to make the picture look a lot brighter then it actually is. This changes the meaning of the picture because it looks like it has been taken at a different time of day. When i decided to change the picture i wanted to make the picture look brighter compared to the original. This picture could be used in a story about the fact were starting to come out of winter and things are starting to brighten up.

Photography and Technology

Capture - Reflected light from an object passes into a camera and then onto a sensitive surface.

Process - The captured image is turned into something we can see.

Store - The image is put onto something we can keep, such as a printed photograph.


Analogue Photography
  1. Light enters camer through lense.

  2. Lights hit sensitive film and reacts with it.

  3. Film removed from camera and put into chemicals for developing in a negative.

  4. Negative projected onto photographic paper and printed using more chemical

Digital Photgraphy

  1. Light enters camera though lense and hits light sensitive sensor.

  2. Signal from sensor converted into digital data by a processor.

  3. Digital data stored as an image on a storage medium in the camera.

USB- A physical connection used by cameras and scanners, possibly the fastest option.


Removeable Card- Images can be captured by a digital device onto a removeable card. Can be connected to a computer by a card reader.


WiFi- Some cameras use WiFi technology to send digital images to a computer.


Bluetooth- Mobile phones, PDA's and some digital devices can send information to other bluetooth devices providing they are close to eachother.


RAW Files- These files have not been processed by the camera. They can be printed or edited with computer editing software. RAW files are very large and not all software can edit them. Computers can correct RAW files more sucessfully than those that have been processed by a camera.


JPEG- This stands for Joint Photographic Experts Group. These set the standard of photo compression. When a captured image is turned into a JPEG, quality is sacrficed for a reduction in the size of the file, consequently this is known as a "lossy" process.

The table below shows the different file types images can come in and their uses.

Aperture and Shutter Speed

Shutter speed - How quick the shutter opens to let light into the lense for a picture to be processed.

Aperture - How big the opening of the lense is.

Shutter speed is measured in seconds.
1/250th of a second is considered fast, while 1/30th of a second is considered slow. A picture cannot be taken under 1/20th of a second without the use of a tripod.

Exposure is the amount of light that reaches the cameras digital sensor. This can be controlled on a camera by different functions.

On a camera usually the shutter speed is label "T" and the aperture labeled "A"

Aperture is usually expressed in F-Numbers.
F/2.1 is large while F/22 is small.

If the aperture is large (for example F/2.1) the shutter speed must be fast (for example, 1/250th of a second). If the aperture is small (for example F/22) then the shutter speed must be slower (for example 1/30th of a second.)

The higher the aperture is the smaller the hole in the camera will be to let light through to the light sensitive surfaces which process the picture.
