Tutorial Two is going to focus on Digital Imaging

Digital imaging is defined as "the art of making digital images – photographs, printed texts, or artwork - through the use of a digital camera or image machine, or by scanning them as a document. Each image is compiled of a certain amount of pixels, which are then mapped onto a grid and stored in a sequence by a computer." (Wise Geek, n.d.)


Some hardware and software that I am familiar with are:


  • Video cameras
  • Webcams
  • Digital cameras
  • Laptops
  • Camera phones

These digital imaging devices can be uploaded, stored, edited, and shared on a computer.  Information technology available on computer and internet can be used such as: facebook - a social networking site, flickr - a photo storage website, and photoshop - a software that enables you to edit photos (here is a link for an example of removing red eye in photoshop http://www.youtube.com/watch?v=VtQ9mx4v-7w&playnext=1&list=PL13527AE22CA0A8D5.


For an added extra: 
Here is a link on how to use flickr  http://www.youtube.com/watch?v=3R_MWGFvDEE.

 
The statement 'A new technology is rarely superior to an old one in every feature', do I agree with this statement.  No, I think new technology is more superior.  Why? well for example cameras:  cameras have now developed from cameras requiring film to digital cameras requiring either a camera with good memory space or a memory card which is inserted into the camera to store photos.  I like the new technology as you can store a lot more photos onto a memory card as you would on a film.  Additionally, a digital camera also allows you to be able to view, edit, delete, and not have to develop photos that have been taken.


It is important to highlight the ethical issues which may arise with the use of image capturing and distribution of digital imaging.  Privacy needs to be considered when taking a photo, you need to have consent before taking, and keeping a photo.  Copyright is another factor to consider; consent is required when the photo has been taken by someone else, as they own this photo.


In Occupational therapy practice photos are being used, for example in client notes, this is great for putting a face to the name.  Also another use of digital imaging in Occupational therapy is in housing modifications, this is great to capture a clients space that is going to be worked with.  In all cases an Occupational therapist would require consent to take photos.
