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?
Like all new pieces of technology there are pros and cons to go along with it. Traditional film based cameras have the advantage of clear quality photographs which are a surprise as to how they are going to turn out and actually require skill to take a truly good photo where as digital cameras do not. However digital cameras also have advantages. Cheap photo printing (you are even able print photos in your own home), larger memory capacity, transferrable to other technology, can edit photos prior to printing them, optical and digital zoom, user friendly with a larger screen to see the image on.

List some of the ways that digital images can be stored transferred and manipulated using other communications technology.
Digital cameras can store images on the camera itself, on a memory (SD) card, computers (online and on the hard drive), cell phones, USBs and iPods etc. The advantage of this over traditional film based cameras is that you can then delete the photos when you are ready and reuse the storage space. To transfer the photos you can often use the same technology which can often be shared between devices or have a send option. The editing function is usually attached to such devices as the camera itself, cell phones, computer programmes and in store photo printing machines.

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.
Increased ethical issues surround digital photography due to the easy transference of images. Someone may take a picture of someone else and place it on the internet without their consent where people all around the world are able to access the image.

Briefly discuss some of the ways that digital images could, or are, being used in occupational therapy practice (include reference and links to any web sites, or blogs you might come across)
Digital cameras are coming more common place in Occupational Therapy settings. On my last placement (FW 3) digital cameras were used to take photos of students and make memory cards of things familiar to them.

Provide a brief summary of the services offered by Flickr.com
The website http://www.flickr.com/ is an online community where account holders are able to upload, store and share images. This site is renowned for bloggers storing their images here.

Name one other photo storage website which offers a service similar to Flickr.com
Another photo storage website which offers a service similar to flickr is http://www.photobucket.com/

Explain what the difference is between a digital and an optical zoom
Most new digital cameras have both optical and digital zoom but what is the difference.

Optical zoom is a better quality zoom as the camera lens moves in closer to the object when taking the photo to magnify the image.
Digital zoom crops the image and enlarges that cropped area until it fills the screen area causing a loss of picture quality.

Explain what is meant by the term megapixel
Each digital image is made up of millions of tiny squares (pixels).
1 Megapixel (MP)= 1 million pixels.
A camera with 3 MPs would be sufficient if producing 6x4 photos however a larger pixel count would be better for producing larger photos.
