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? ********
Digital images can be transferred and stored in a number of ways such as emails can be sent through the internet, cell phones, and if scanning this can be done through some photocopiers. Images taken on cell phones can be sent to other cell phones. Scanners, photocopies, cameras, webcams are all ways of storing or sending information.
When taking pictures ethical considerations must be taken into account. If the pictures are going to be used for things like advertising where the public will have access to them, consent must be gained from the people in the photo.
Digital imaging is being used all the time by occupational therapist to record client progress and clients using equipment. They can be used as evidence to show what the OT has done.
Flickr.com is a photo management tool and is a way to get your photos and videos to the people you want to share them with. Basic accounts are also free so there is no reason not to join.
Other sites where you can share photos are social networking sites like bebo.com and facebook.com that are very commonly used.
The difference between digital and optical zoom: Digital zoom simply crops the image to a smaller size then enlarges the cropped version to fit the frame. Digital zoom results in significant loss of quality where as optical zoom stays high throughout the zoom range.
Digital cameras capture images as pixel elements, known as pixels and a megapixel is equal to one million pixels. Digital images are made up of thousands of these tiny, tile-like picture elements. The more pixels, the higher the image resolution. From:
