This weeks tutorial was about digital cameras, ethics and methods of image storage. The points covered in the tutorial are recorded below.
In considering the statement "A new technology is rarely superior to an old one in every feature" it is easy to see this is the case with digital cameras. Although digital cameras are far superior in terms of being able to see immediately whether the desired result has been achieved or not, there are still issues with regard to photo quality. Also while taking the shot it can sometimes be difficult to see the detail on the screen. Having said that, being able to take as many photos as desired with the ability to delete unwanted ones, and to upload photos directly from a digital camera to a computer is a huge advantage.

Images can be stored on the hard drive of a personal computer, on a disc or on a photo storage website such as Flickr (more on this later in the blog). Images can be digitally enhanced or manipulated using software such as Photoshop, they can be transferred via email, memory sicks, camera leads.
In considering the prevalence of image caturing devices there are ethical issues surrounding the use of this technology. Invasion of privacy, eg taking photos of others without consent, using devices for inappropriate means and manipulation of images would be three that come to mind.
Some of the ways in which digital images are being used in occupational therapy practice include home visit assessments, for example taking photos of entrance ways, or areas that require modifications. Images could be used to back up funding applications.
Flickr.com is a free website that allows members to store, sort, search and share photos online. As you will see throughout this blog I'll upload a few of my own photos. There are other photostorage websites offering similar services, one of these is Fotki, check it out at :http://contests.fotki.com/contests/weekly_may26/266674707.html
In considering the difference between a digital zoom and an optical zoom the optical zoom actually focuses in more, whilst the digital zoom reduces the number of pixels and drops the outside ones off, decreasing the quality of the image.
A pixel is one of the millions of squares that makes up a digital image, today's images usually vary between 1 and 14 million pixels. One mega pixel equals one million pixels, two megapixels equals two million pixels etc. (wikipedia, 2010).
