How does it work?
           You  don’t  need  to  be  a  Computer  wizard  to  use  digital  cameras.  Put
        simply,  what  happens  is  that  the  camera  produces  your  picture  in  digital
        format  -   i.e.,  made  up  of  pixels  -   so  that  it  can  then  be  “read”  hy  your
        Computer.  3.....................  They  can  be  saved  until  you  want  to  use  them,
        included  in  letters  you’ve  written  on  your  Computer  or  sent  to  friends  and
        family in an e-mail.
        Which type of digital camera should I buy?
           First  of all,  when you’re looking at digital  cameras and thinking,  “Which
        one shall I buy?”, bear in mind that nobody yet knows what a digital camera
        ought to look like, so there are lots of strange shapes and sizes. 4...................
           Secondly,  there  is  the  cost.  At  the  cheaper  end  of the  market,  there  are
        the  “point  and  shoot”  cameras.  These  cameras  are  fully  automatic  and
        anybody just  starting  digital  photography  should  begin  with  one  of  these.
        They’re  so  simple  that  after  only  a couple  of weeks,  you  should  have  learnt
        all you need to know about how to use the camera.  5................... Some of these
        are  a bit  too  complicated  for  everyday use.  At  the  top  end  of the  price  scale
        are proíessional cameras and digital video cameras -  very expensive and only
        necessary for the serious photographer.
