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 cameras still takes photos and only if you know how to use the special features within the camera, your photos will be basic and much similar to the photos taken with a manual camera.

However knowing how to use a digital properly you are able to have differnt settings and edit photos before the print process. The new digital cameras are much smaller so are easier to carry with you as opposed to carrying a manual with a large zoom capsule and extra films. Yet the older cameras are much more durable and easier to repair when broken.
List some of the ways that digital images can be stored, transferred and manipulated using other communications technology.
List some of the ways that digital images can be stored, transferred and manipulated using other communications technology.
-USB
-Printers
-Photoshop and other similar programs
-Internal and External memory
-Loaded onto storage websites-Blogs
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.
Taking photos without first gaining permission from the people in the photo, loading photos onto inappropriate sites, stealing others photos from their pages.
Briefly discuss some of the ways that digital images could, or are, being used in occupational therapy practice.
- Take photos of equipment to refer to at a later date
- A way to record a clients progress so they can see visually for themselves
- Fast way to send evidence to other staff in other locations
Provide a brief summary of the services offered by Flickr.com
A website where people can store and share their photos with others, they can be uploaded from a desktop, USB or even forom a camera phone. From there, they can be edited and organised even labelled who is in the photo, when and where it was taken.
Name one other photo storage website which offers a service similar to Flickr.com

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.What digital zoom does is enlarge a portion of the image, thus 'simulating' optical zoom. In other words, the camera crops a portion of the image and then enlarges it back to size. In so doing, you lose image quality.
Explain what is meant by the term mega pixel
A mega pixel refers to one million pixels, and is commonly used in reference to digital cameras as an indication of resolution capability. A pixel is a tiny square on a computerised display that is so small it appears as a dot. The display screen is a solid grid of these squares or dots, which can be easily seen with a magnifying glass. The more pixels or dots that make up the display screen, the clearer the resolution or image will be. Greater numbers of dots or pixels allow for more refinement of the image, which results in higher, truer image replication.
