“A new technology is rarely superior to an old one in every feature”. I think this statement is probably true to a large extent. Some of the positives, in relation to digital camera technology over conventional cameras, include: reduced cost of processing; instant viewing; the ability to delete ‘dud’ photos; the ability to share easily with others and future improvement of features possible. Negatives include; the quality of the photos is reduced, the cost of keeping up with new technology can he high; storage issues (size, organisation, security and durability of storage systems); breaches of personal privacy and confidentiality and people are less likely to print photos and place in albums leading to limited access to those without computer technology (digital divide).
There are many forms of communications technology which can either capture, store, transfer or manipulate digital images these include; digital cameras, cell phones, web cams, digital video cameras, CCTV, iPods and computers.
Computer technology and lack of internet security means that others have easy access to images making privacy and confidentiality major considerations. This in turn raises issues around ownership, responsibility and consent to use, safety of individuals may also be compromised, for example the photographing of SAS troops in Afghanistan.
Occupational Therapy use of digital images could include: videoing of assessments plus before and after comparisons of interventions. Digital imagery can also provide teaching and learning applications for occupational therapy students, (http://www.uea.ac.uk/foh/news/creativity-chanllenge) and also for teaching and learning opportunities with clients - with digital images therapists are able to show clients what they are actually doing and also what they could be doing. Digital imagery can also provide occupation for clients – both work and leisure. It can be used as a means of recording images as a memory aid eg photo albums, as visual aids to intellectually impaired (especially those who are unable to read), for long distance consultations and as a connection to peers via blogs ( http://otegypt.blogspot.com/); or for advertising of OT services.
Flickr.com is a web site that provides a means of uploading, organising and sharing digital images (including videos) on the internet. It also provides a platform for an on-line community. There is limited access is free to users – unlimited access is available at a cost. Websites similar to Flickr.com include: Photobucket; Image Shack, Kodak Easy Share Gallery and Fotolog.

Digital Image terminology explained:
Optical zoom uses the lens of the camera to enlarge the image – the same as a conventional camera. Digital zoom simply enlarges the pixels electronically in the middle of the picture and deletes the outer pixels – therefore you immediately get reduced quality as the pixel count for the picture is reduced.

A pixel is shorthand for ‘picture element’ or little picture dot. Mega is shorthand for ‘million’ – therefore one megapixel (mp) means one million picture elements. Generally speaking the more pixels the better the quality. A camera with 8mp is sufficient to provide resolution to produce good quality 8” x 10” photos. http://www.photography101.org/basics/megapixels_explained.html

Tutorial One - Information Technology and Ethical Issues
This content of this post is taken from Tutorial One Worksheet -
Information Technology (IT) / Information Communications Technology (ICT) refers to anything related to computing technology, such as networking, hardware, software, the Internet, or the people that work with these technologies.
http://www.techterms.com/definition/it
We now live in what has been termed the ‘information age’ and regard IT as part of our everyday lives. Even in very poor countries IT is emerging as a recognised communication system – when I was in Madagascar 5 years ago I travelled 3 hours from the nearest town along dirt roads to find a single building at the road end which had a computer installed and internet access!
I’m comfortable using my cellphone, computer, the internet, e-mail, Otago Polytechnic on-line learning (although get frustrated with all systems at times). I’ve just set up skype to talk ‘free’ to my son while he is studying but I am not so keen on chat rooms, message boards, social networking etc. and prefer to get out and about for my social interaction rather than be tied to my computer.
Very little IT was used in my fieldwork experience. My supervisor was a very reluctant IT user although other OT’s in the setting were proficient with the vehicle bookings, enable requests, internal e-mail etc. Patient notes were still hand written but could be computerised. Community OT’s used cellphones to check with clients. There is potential for much greater use – prior to study I worked with a child who was non-verbal – she had a computer that enabled her to formulate sentences and speak words.
Ethically there are potential problems with consent, privacy, safe storage of information, keeping information free from corruption & copy write.
Computer Ethics
This is a set of moral principles that regulate the use of computers. Some common issues of computer ethics include intellectual property rights (such as copyrighted electronic content), privacy concerns, and how computers affect society.

Intellectual property
This refers to the ownership of intangible and non-physical goods. This includes ideas, names, designs, symbols, artwork, writings, and other creations. It also refers to digital media, such as audio and video clips that can be downloaded online. Since intellectual property is intangible, it is more difficult to protect than other types of property.

Social Justice
This is the overall fairness of a society in its divisions and distributions of rewards and burdens
http://www.sociologyguide.com/weaker-section-and-minorities/Social-Justice.php
In IT terms this could relate to the disadvantage of students who are unable to afford computers and should society – to be fair – provide these students with computers.
Informed Consent
This is consent given with full knowledge of the risks involved, probable consequences and the risks involved.

First Posting
This is my first time using a Blog so it is all a bit confusing - hopefully all will become clear.
