Tutorial Two: 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? Digital camera's are more instant and if the image is not what you want it can be edited or deleted straight away and then the shot can possibly be retaken. You do not have to wait for the film to be developed before you can see your image. The camera can also store lots of images and you can then print them through your home PC or taking them into the shop for processing.

List some of the ways that digital images can be stored transferred and manipulated using other communications technology. Images can be printed into a hard copy. They can be loaded into a PC and then emailed to others and they can be used in Web pages. The images can be stored straight into a PC or they can be stored onto a CD Rom

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. The person who has had their image captured has no control over what happens to this after the image has been taken. It can be used in many ways without their knowledge or consent. The image can be altered and used in an inappropriate way and this can be distressing for the owner of the image.

Briefly discuss some of the ways that digital images could, or are, being used in occupational therapy practice. Digital images can be used by occupational therapy to assist clients that need a photo profile of task. This can be used into a book that can be used as a hard copy of the client to follow. They can be used in a return to work situation where the client needs memory joggers to follow a task if they are using compensatory techniques.

Explain what the difference is between a digital and an optical zoom Digital zoom relates to how clear the image appears. The larger the number of digital zoom the more pixels you have and this gives greater clarity to your digital images. Optical zoom enlarges the picture but keeps the clarity of the image without distorting the colour or image.

Explain what is meant by the term mega pixel Pixels are the littler byts of colour that go to make up the total image. It is a little Byte of colour that captures that specific piece of the image and each of these pixels combine to make the total image.
