Tutorial 2: Digital Imaging

The purpose of this blog is to explain some of the things that are used along side digital imagery, exlore the positive and negatives between digital cameras and traditional film based cameras. I will also address the ethical issues that may arise with the use of digital capturing and the distribution using IT, and discuss some of the ways digital images could be used in Occupational Therapy practice.

List some if the ways that digital images are stored transferred and manipulated using IT 

  • USB flash drives
  • Compact disk (CD)
  • Digital vesitile disk (DVD)
  • Hard drive
  • Microphone
  • Printer
  • Mouse
  • Keyboard
  • Graphics card
  • Video games
  • Word processors (exel, microsoft word etc)
  • Photoshops
  • Internet explorer
  • Virus protections e.g Firewalls
Examples of the use of digital imaging that provide information and recording include use of webcams, video cameras, digital cameras. Webcams can be used to produce live recordings via the internet which can be viewed by others on the internet on programmes such as skype, and can be used to capture pictures whilst sitting at a computer, and for quick uploads. Digital cameras produce digital images of scenes that are located anywhere and uploaded to a computer at a later date, most digital cameras also produce videos if put on to the movie setting but are there for mainly short snipits of video. Video cameras capture any length of film and are a better quality than a digital camera. The footage is then later uploaded to a computer to be edited and uploaded elsewhere.

Pluses and minuses of digital camera technology in relation to traditional film based cameras:
Pluses: - Photos can be previewed and deleated it the camera
- Only required photos can be uploaded to another device such as computers
- With photoshops, photos can be edited with texts and looks (e.g black and white, sepia)

Ethical issues that may arise with the use of image capturing and distribution using IT can include privacy, for example posting a specific photo of a person / people on the internet with no informed consent. Photos on certain sites could be taken by an unknown person and could possibly later be passed off as their own.

Some of the ways occupational therapists could use digital images in OT practice include;
  • The use of documentation to monitor a clients progress ( used in physical tasks)
  • Evidence
