LISTENING
1. Study this description and answer these questions.
-
How do digital cameras differ from conventional cameras?
-
How do they work?
-
What are their advantages and disadvantages compared to conventional cameras?
How a digital camera works
Digital cameras store images on memory cards so pictures can be transferred easily to a computer.
A lens focuses the image on to a CCD unit or Charge-Coupled Device where the film would normally be.
So you can aim the camera accurately, there is an optical viewfinder.
So you can play back the images and decide which to keep and which to re-shoot, the image is passed to a small LCD screen on the back of the camera.
2. Listen to Part 1 of this discussion between A and B and complete this table of similarities and differences between conventional and digital cameras. Tick (v) or cross (x) the boxes.

|
|
3. Listen to Part 2 of the dialogue to list the disadvantages of digital cameras.
4. Now listen to both parts again to find the answers to these questions:
-
What does a CCD contain?
-
What is a pixel?
-
How can you view pictures before they are downloaded to a PC?
-
When you have downloaded the images, what can you do with them?
-
Is special software required?
-
Why is the resolution important?
-
What does the capacity of a digital camera depend on?
-
Why is it worth getting a rechargeable battery?
5. Compare digital and conventional cameras. Use the table from exercise 2.
6. Study this data about storage devices. Then complete the blanks in the following sentences comparing and contrasting the different types. Use the words: both, like, unlike, whereas, but, however.
