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? Newer cameras have the ability to be multifunctional, for example they are able to take still pictures as well as movie frames. However in some digital cameras the technology used to zoom, and transfer onto computer or file cause a loss of definition, although on the other side of that they are able to zoom further. |
| List some of the ways that digital images can be stored transferred and manipulated using other communications technology. Images can be stored either on the memory card of the camera or transferred to a file in a computer. From the computer you are able to zoom, distort, change colours and increase or decrease the overall size and look of the image. |
| 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. Due to their prevalence and the ease of use these devices may overtake conventional methods of data gathering and storage of information. For example, when an interview is taped rather than the interviewer having to pay attention and write information down and also using computer files to store information rather than having hard copies. The danger there of course is if the system crashes and data is not backed up somewhere or no hard copy was made. |
| Briefly discuss some of the ways that digital images could, or are, being used in occupational therapy practice. To document a home visit in order to show proof in a report of what changes need to be made. To document trips or special moments in a client’s therapy, in order to create a diary of their progress. To capture images of ROM or something similar to compare with later in treatment. |
| Provide a brief summary of the services offered by Flickr.com Flickr is an image and video hosting website, web services suite, and online community platform. In addition to being a popular Web site for users to share personal photographs, the service is widely used by bloggers as a photo repository. Its popularity has been fueled by its organization tools, which allow photos to be tagged and browsed by folksonomic means. As of November 2007, it hosts more than two billion images. http://en.wikipedia.org/wiki/Flickr: Retrieved 26 May 2008 |
| Name one other photo storage website which offers a service similar to Flickr.com Photobucket is also a site which allows photos to be stored and shared via the internet. |
| Explain what the difference is between a digital and an optical zoom Optical zoom works just like a zoom lens on a film camera. The lens changes focal length and magnification as it is zoomed. Image quality stays high throughout the zoom range. Digital zoom simply crops the image to a smaller size, then enlarges the cropped portion to fill the frame again. Digital zoom results in a significant loss of quality as is clear from the examples below. |
| Explain what is meant by the term mega pixel A mega pixel is one million pixels. Pixels are what make up the picture. The bigger picture that is being printed then the bigger pixel count you are going to want in order for a clear picture to be produced |
