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? +ves: the process of taking photos and then being able to work with them and see them is almost instant in comparison to film. Digital is a lot more cost effective and less wasteful as you are not paying for the film and other materials and you can simply delete any unwanted/ dud photos. Digital allows you more uninterrupted photo taking time as you do not have to fiddle around changing films and the memory capabilities allow many more photos to be taken. -ves: often the quality of digital is not as good as film. The processing of film means you have a more permanent copy of the photo rather than files on the computer which can be lost quite easily. The ease at which digital photos can be distributed may mean it is harder to keep track of who has access to the photos and therefore is confidentiality still intact or the photos are open to misuse. |
| List some of the ways that digital images can be stored transferred and manipulated using other communications technology. Email Put on disc or stored on a memory stick Used in presentations Printed Posted on a blog or website Used in client notes or in a funding application |
| 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. If posted on a blog you need to be aware of how much control you have over who views the images and will this breach confidentiality of a client and do you have the permission of the involved parties. You also need to decide whether the material you post is appropriate and/or respectful of the purpose of the blog or website, and being aware of who will see it and is this ok. In regards to use of image capturing devices the user must be aware of the purpose of using it, will using it be of benefit to others and just making sure everyone knows how you intend to use the images. |
| Briefly discuss some of the ways that digital images could, or are, being used in occupational therapy practice. To take photos of certain aspects of a client’s house or wheelchair so the therapist can then make a plan for modifications and/or apply for funding. Recording group activities. Taking photos of equipment they see at expos or just out and about. Photos of equipment, clients, activities in action. These photos can then be shared with the team, other therapists, show to clients. |
| Provide a brief summary of the services offered by Flickr.com It is an interactive photo storage website where people can put their photos and share them with others. It is a way of managing them and making them available to others. |
| Name one other photo storage website which offers a service similar to Flickr.com Photo bucket |
| Explain what the difference is between a digital and an optical zoom “Optical zoom uses the optics (lens) of the camera to bring the subject closer” where as digital zoom just takes a section of the photo and enlarges it, meaning the photo quality decreases as you digitally zoom in. (Optical is the real zoom). Retrieved from: http://www.photoxels.com/article-optical-digital-zoom.html on 4 june 2008. |
| Explain what is meant by the term mega pixel A megapixel is one million pixels. And a pixel is the smallest piece of information in a picture. Pixels are normally arranged in a regular 2-dimensional grid, and are often represented using dots or squares. Retrieved from: http://en.wikipedia.org/wiki/Pixel on 4 June 2008. |
