Tutorial 2 - Digital Camera

"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?

I just loved going to the photo shop to pick up my pictures. Sometimes, were are some on the film that I had forgotten and it was always a nice surprise to see pictures and remember what happened at that time. Now, the thrill is gone. Instantaneously you can see what the picture looks like and you can take nearly unlimited amounts of pictures. Which can be a good thing, but do you ever look at all of them? I surely don't And if I do, and want to show them to my friends, they must be quite tolerant to see all of them, because often there are at least 10 of the same thing from different angles...


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

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 and anonymity can be hurt. To publish a picture of someone or someone's belongings, it is important to get informed consent first. By editing pictures, wrong impressions of people can be given, which may result in legal issues.


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

Digital pictures can be taken of people's houses or rooms that are needed to be modified. Digital pictures are useful here as they can be emailed to the funder. The OT can also draw into the photos to pinpoint the problem.
Digital pictures can also be used to analyse a person's posture.

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

Digital zoom just cuts out a piece of the picture and blows it up. This results in poorer quiality as the pixel count gets significantly reduced.
Optical zoom is the zoom of a film camera (an old fashioned one). The lens itself changes its length which is why objects appear magnified.


Explain what is meant by the term mega pixel.

One MP or megapixel is the pixel count of one million pixel.
