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? The old 33mm film you took your photos then took the roll to the camera shop to be developed, you had to finish the roll before doing this and did not know if the photos would be any good, however you did get a physical copy of the photos. With digital photography you can see the result immediately and delete and reshoot if required. You can load these photos anytime you want onto your computer, save, edit and send these photos to family and friends around the world. Often this is as far as we go with the process, many of us don’t bother to print the photos to get a physical copy, therefore denying future generations of this record of history. The photos we do go to the effort to print are of a lesser quality than the traditional photos and the quality of these tend to fade as years go by.

List some of the ways that digital images can be stored transferred and manipulated using other communications technology. Cd, computer, memory cards, Using programmes like photoshop, picassa, and photo express to edit and alter or enhance photos. Some programmes add gimmics or distortions for added effects.

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. Cell phones have been banned from some public places like swimming pools and gymnastic competitions to protect the public from exploitation as photos can be taken so discreetly with devices so small people are unaware their image has been taken, potentially breaching their right to privacy.

Briefly discuss some of the ways that digital images could, or are, being used in occupational therapy practice. When dealing with adaptations it is common practice to take digital images, this gives an accurate record, saves time with free hand drawings and allows us to manipulate the image to aid planning adaptations. Before and after shots are always handy to keep on file for future reference.
