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.
The digital camera has taken away from the excitement of getting a film developed. Often the essence of a photo is the shear "capture" of the moment. Where as digital cameras are able to be edited prior to printing or deleted at the time and re taken if the photo may be undesirable.
List some of the ways that digital images can be stored transferred and manipulated using other communications technology.
Images can be stored on computers and disc either CD or DVD. They can also be kept on an external hard drive or in a USB stick. There are programs on the computer such as photo shop that can "polish" the image, deleting unwanted things and making the image look different.
Consider what sort of ethical issues may arise with their use.
Because capturing an image is so quick and easy to do, permission may not be sought and this may offend someone. Privacy issues may arise when an object or person is included in an image without being told or asked before hand.
Briefly discuss some of the ways that digital images could, or are, being used in occupational therapy practice.
Digital images may be used for home modifications; if a therapist cannot get to a client’s house then another person may take photos and send them. Also could be used to jog a therapist’s memory about a particular concern such as a piece of equipment.

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
Digital zoom lessens the quality of the image taken as it merely crops the photo down in size and makes it larger. Optical zoom on the other hand actually changes the length of the zoom lens and magnification stays at the same quality depending on how many pixels your camera has.
Explain what is meant by the term mega pixel
A pixel is a tiny square in which a digital image is made up of. The more mega pixels your camera has the better the resolution and quality will be on your image especially if you enlarge it.
