Digital Camera use and applications

• "A new technology is rarely superior to an old one in every feature"
  Technology is in some respects superior in which it has allowed for improvement in living, efficient access to information and has increased our ability to keep in contact with loved ones around the world. However in view of the superiority of new technology there has been devastating affects on generation y and beyond as children in developed countries, especially western ones, are not learning basic motor coordination skills and balance.
  
  A minus is some technologies are useless in relation to their intended function, design and the expectation of the user. Some technology only appear better than the one they have attempted to replace, but there has only been a change in appearance. For example the device is slimmer with a colour selection.
  
  A plus in using new technology that has successfully been improved makes people's occupations easier and more inefficient. For example with the introduction of roaming internet has allowed people to work while traveling.

• Ethical Issues that arise from the use of image capturing devices:
  Digital cameras can go most places; in a variety of environments and can preform a range of tasks. For example zooming, taking out red eye and can change the colour tone of our photo. In photo shop people are able to change their appearances. This ability brings up issues of identity; ie the loss of identity.
  
  The inability to control when and where an image is taken of you is becoming more and more prevalent is society. We especially see this with famous people and the media. The media produce thousands of copies of magazines which contain photographs of celebrities. These photos are not with consent. Celebrities are finding it harder than ever to keep their privacy and what they do when the movie camera is not on them.
  
  Inclusion ethical issues are; lack of privacy, no informed consent of the photo taken and its intended purpose, and people's inability to control what happens to their photo- where it is stored and who views it.

• The difference between digital and optical zoom:
  Optical zoom occurs before the photo is take and digital zoom happens after the photo is taken. Geneally on the camera's screen or on a computer screen.
  
  In optical zoom the lense changes focal length and magnification while the quality of the image stays the same. Whereas digital zoom crops the image to a smaller size, then enlargers the cropped protion to fill the frame again. This decreases the quality of the image.
