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?
Positives:
You can take a picture and delete it straight away if you don’t like it
Some tend to be a lot more clearer images depending on the mega pixels and the type of camera and how much the image is zoomed in
You can download them onto the computer if you have a full memory and then delete all the photos so you have room again on your camera
They are cheaper to get developed depending on what size you are getting
You can more control over what you want the colour of your photo to turn out like


Negatives:
Overall traditional film based cameras have a clearer image for example: If you were to blow up an image to a big size the quality of the image would still be there are just as clear.
When buying yourself a digital camera you may need to pay a lot to get a good camera. But is you went out and got yourself a film based camera it wouldn’t matter how much you had to pay for it whether it was cheap or dear you would still get good quality images.
Film cameras also allow for a Varity of filters and lenses, giving the photographer a much fuller spectrum in which to work with.

List some of the ways that digital images can be stored transferred and manipulated using other communications technology.
Digital images are good in how you can do so many things with them. For example You can put all of your photos onto the computer and make a slide show. From there you can put them onto a memory stick. Digital images can also be taken on cell phones and sent to other cell phones. You can also download photos onto a disk and then play it into a DVD player so that you can watch them on T.V.

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.
Ethical issues are one of the things that come about quite a lot on the internet as it is something that anyone in the world can access. Things such as taking pictures of people who haven’t given their informed consent. These would then get put onto the internet. It is so hard to stop this from happening as the internet is such a huge network and there are just too many ways that images can be changed or displayed on the internet.

Briefly discuss some of the ways that digital images could, or are, being used in occupational therapy practice.
Digital images would be used in occupational therapy practice quite a bit if you were working with housing modifications or wheelchairs. These would be taken a picture of so that the occupational therapist could work out a plan or send away for a quote that would best suit that particular individual. Digital images may come in handy for taking pictures of equipment that already exists. Digital zoom has end result of being poor the clearness and quality of the image.

Provide a brief summary of the services offered by Flickr.com
Flicker is a good site to all sorts of things with your photos. For example on Flicker you can shear photos with friend’s family or anyone who may live around the world. Another good thing that you can do with your photos once you have got them on there is you can edit them and change if wished. You can change the colour and size of them.

Name one other photo storage website which offers a service similar to Flickr.com
There is another photo storage like Flicker that does the same type of thing this is Shutterfly. It is a website that has unlimited picture storage and it has instant online photo shearing.

Explain what the difference is between a digital and an optical zoom
Most cameras that we have these days have got both digital zoom and optical zoom.
Firstly the optical zoom is like a lens on a film camera. When it zooms in the focal length and magnification takes place. When this happens the quality of what is zoomed in keeps it’s high quality throughout the zoom range. Then there is digital zoom. This crops the image to a smaller size it then enlarges the cropped portion till fill the frame again.


Explain what is meant by the term mega pixel
Mega pixels are the amount of individual pixels that go into making a image.
These days the number of pixels can range from 1 million which is referred as 1 mega pixel to 14 million which is referred as 14 mega pixels. Depending on how many pixels a digital camera has on it would all depend on how excellent prints come out depending on what size you have chosen to get them developed on. For example: a 3 mega pixel camera can make excellent 4”x6” prints.
