Tutorial 2...

Digital Camera use and applications…

“A new technology is rarely superior to an old one in every feature”. Briefly discuss this statement in relation to digital camera technology. What would you consider to be some of the pluses and minuses digital camera technology holds in relation to more traditional film based cameras?

The 'good things'.... photos are instant and able to be viewed and deleted,

- choice of what to develop

- choice of camera size and complexity for user

- ease to copy to computer for manipulation i.e photo shop

The 'not so good things'....

- loss of the anticipated ''getting the film back from the camera shop' excitement

- complexity of camera functions requires technical knowledge

- increased battery usage

- expense

- no hard copy of photos as most are stored electronically

List some of the ways that digital images can be stored transferred and manipulated using other communications technology.

Stored and transferred: flash drives, hard drives, websites - social networks, Cd, Dvd, memory cards, email, cell phones

Manipulated: computer programs, instant photo developing in shops.

Given the prevalence of image capturing devices, and thinking about the issues discussed in tutorial one, consider what sort of ethical issues may arise with their use.

- Privacy

- misuse of e g copyright

- trustworthiness.... downloading

- The right people receiving the information.

Briefly discuss some of the ways that digital images could, or are, being used in occupational therapy practice.

-photo documentation and recording of clients in everyday occupations, i.e walking cooking exercising for assessment purposes and formulation.

- documentation for housing modifications

- development of in service manuals and promotional material


Provide a brief summary of the services offered by Flickr.com

Flickr is a photo management and sharing application on the web used to upload, organise, and share photos. To use, firstly a basic account is set up, where photos are then stored. It also offers services for 'making stuff' eg cards and framed prints and recieving updates from friends and family.

Name one other photo storage website which offers a service similar to Flickr.com-

- Ringo
- Snapfish

Explain what the difference is between a digital and an optical zoom

A digital zoom crops an image to a smaller size, then enlarges the cropped portion to fill the frame, thus resulting in a loss of quality the larger it gets.

An optical zoom uses the lens to focus, through changing focal length and magnification as it is zoomed The subject is enlarged with the image quality staying high.

Explain what is meant by the term mega pixel

A pixel is a contraction of the term PIcture ELement. Digital images are made up of small squares (pixels) like a tile mosaic. A mega pixel is one thousand pixels.
