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?
This statement is correct in relation to cameras. The digital camera has some get benefits but some down sides as does the digital camera. The great thing about the digital camera is that many photos can be taken. They then can be either stored or deleted. The photo can also be checked almost immediately to see if it is ok or if another photo needs to be taken. The down side of having a digital camera is that the quality of the photo is not as good as one taken by a film camera. Also the digital camera requires batteries which rum out often and need frequent recharging.
The one of the advantages of having a film camera is that the quality of the photo is better. Also the camera doesn’t require constant recharging. The down side is that the cost of having the film produced is high and that there is a limit to how many photos can be taken on one roll of film.

List some of the ways that digital images can be stored transferred and manipulated using other communications technology.
Digital images can be stored in cameras, cell phones, computer hard drives, CD-ROMs and USBs as well as other varied storage devices. Digital images can also be changed by programs such as Microsoft Movie Maker. Images can be cropped, change colour, merge and have other images superimposed into them. Nearly anything can be done to digital images.

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 and publishing them with out the permission of the person in the photo is illegal. It affects clients’ right to privacy and confidentiality.

Briefly discuss some of the ways that digital images could, or are, being used in occupational therapy practice.
The use of digital images is of a lot use in Occupational Therapy practice. As it is said “a picture is worth a thousand words”. This is certainly true and is very useful in OT practice. Digital photos can be used as a record of many things. They can be used to record injury progress, before and after shots for housing modifications and they can be proof that an event occurred. Of course permission of the subjects is needed before the taking of the photo.

Explain what the difference is between a digital and an optical zoom.
Optical zoom is when the image is focused in on one point so that the small detail can be seen. The quality of the picture remains the same. Digital zoom is when the image is cropped and enlarged. The quality is poor with digital zoom. It is always better to have optical zoom.

Explain what is meant by the term mega pixel.
The term “mega pixel” is used to describe one million pixels. It is the amount of pixels in a digital image. The more pixels, the better the image.
