Tutorial 2: Digital Camera Technology

“A new technology is rarely superior to an old one in every feature.”

This statement is suggesting that although technology is constantly changing, the new technology will never really reach a standard of perfection as there are old features that are more reliable at present. This view will most likely reflect a large majority of people who are unwilling to change their old ways and adapt to the new technology, or may not even be competent enough in their abilities to do so.

Digital camera technology is very convenient as the photographs you take are instant and are able to be viewed straight after. This means you can crop, resize, shift, alter or delete the image altogether. This proves to be very cost effective in the long run as there is no wasted images being printed.

The quality of digital camera technology is also constantly improving to create stunning images compared to the older standard versions.
Digital camera technology is also convenient to use as the images can be stored in a number of different ways such as flash drives, computers, digital photo frames and disks. This also means they can be shared by uploading to a website or sent via e-mail. Another convenience is that the images can be printed off at home from the users computer to save waiting time and money from another developer.

Unfortunately having these images stored in these different ways can also mean they are more likely to get lost, accidently deleted or the new technology can prove to be un-reliable and malfunction. While the technology may sound very convenient and better to run it is also more expensive in terms of set up cost as the requirement of having a digital camera will mean the user will also need a memory card, cords, batteries and a computer to view and arrange the photos.

Ethical issues surrounding the use of digital camera technology are things such as photographs being taken of an individual without their permission and then being displayed in public. Misuse or stolen identity can also be an issue with photographs being taken unknowingly and being re created to act as a photograph for someone else. Lastly, digital camera photography can be an invasion of privacy with technology advances meaning a person can be photographed from any location at any time if required.

Digital images can be and are being used in Occupational Therapy practice in a number of ways. This is including assessment such as cognitive assessments to see if the client has figure ground perception etc or memory activities with the client. Pictures can also be taken to recognise the progress the client is making and for the therapist to prove intervention is successful. Pictures can also be used for instructional diagrams and reminders for how to complete tasks, operate equipment, lifting techniques and so on.

Flickr.com is a service that allows the users to share and swap their pictures with others by uploading them to the site, or viewing the pictures others have uploaded. Google images(http://images.google.co.nz/) is another example of a photo sharing or photo storage website.
A digital zoom is when the image is actually being cropped, resulting in a loss of quality as the surrounding pixels and resolution are lost. However an optical zoom magnifies the size of an image by adjusting the lens. Unlike digital zoom, optical zoom enlarges the subject without sacrificing resolution.

A megapixel is equal to one million pixels. Digital images are made up of thousands of these tiny, tile-like picture elements called pixels.
