Digital cameras are often used in Occupational therapy with clients, there are numerous differences between different cameras and this blog identifies these differences and spots the pluses and minuses of traditional cameras and digital cameras.
Some pluses and minuses of digital camera technology and the more traditional film based cameras.
Digital camera technology is smaller and photos from these cameras can be stored and manipulated using other communications technology. With these cameras there is less equipment to carry around and they are much easier to store. However computers can loose files that hold the information from these cameras and as Sunderland (2010) states "new technologies are never totally superior to the older technologies they attempt to replace". These technologies also require more cords etc,so often end up costing more than older cameras.
More traditional film based cameras are larger and store photos on films which provide alot of character for the camera as these cameras are now rare. They are however larger and take up more space and if you want to look back at a picture you've just taken you can't until you've printed the photos, whereas with digital cameras you can look at the photo straight away and delete it or keep it.
Some ways digital images can be stored, transferred and manipulated using other communications technology.
Digital images can be stord on USB's, laptops and computers, on cellphones and Ipods. They can also be stored on websites like facebook and Bebo and can be manipulated on the television and the computer.
Ethical isues that may arise with using digital cameras.
Ensuring that if you're taking a photo of someone that you have their consent and also acquire their consent if you're intending to use that photo for other uses e. g creating a photoboard. Google map is a good example as many people are on this site and are unaware that people all over the world could view them on this website.
Digital camera use in Occupational therapy
Digital cameras are used to take photos of equipment which are uploaded to websites so clients can view the equipment. Cameras are used often to create photoboards for clients to make them feel more at home and facebook pages are often created for youth and photos of them uploaded onto these pages.
An online site where you can do different things with your own digital photos is Flickr.com
Services offeres by Flickr.com:
- Allows you to upload and organise photos
- Lets you make cards, posters, calendars etc. with your own photos
- You are able to view an array of photos uploaded by people from all over the world
- You can join groups to share interests. These groups have a pool for sharing photos and videos and also has a discussion board where people can interact.
Another photo storage website similar to Flickr.com is shutterfly.com
The difference between a digital zoom and an optical zoom
Digital zoom simply crops the image to a smaller size, then enlarges the cropped portion to fill the frame again. It results in a significant loss of quality however optical zoom works just like a zoom lens on a film camera. The lens changes focal length and magnification as it is zoomed. Image quality stays the same throughout the zoom range(Sunderland, 2010).
