“A new technology is rarely superior to an old one in every feature”
In relation to Digital cameras, this statement is suggesting that just because a camera is digital, it does not mean that it can outdo an original film camera in every way. Digital cameras have excelled in many areas such as convenience, efficiency and practicality. This is shown as they are being made smaller, to fit in a handbag or to be hand-held, enabling them to be handy whenever a candid moment arises, as well as enabling the captor to view the photos and delete the unwanted ones, rather than paying money to process the photos, without knowing what they look like.
However many believe that digital cameras do not fully capture the standard of quality in a photo that an old film camera can, believing that overall a film camera is superior to a digital camera in quality of photos.
Because digital images can be put directly onto computers, this means they can be uploaded and stored onto other technologies such as USB sticks, hard drives, the internet and Email. It also means that if the images are stored on certain technologies, that people all over the world may be able to access them. These images can also be manipulated and changed through the use of different computing technologies; this means that photos can be improved in quality by adjusting factors such as red eye, gleam and blurriness.
The main ethical issue arising with the increase of digital imagery, and of other technologies which enhance this (computers, internet), is confidentiality. This is due to digital cameras being so discrete that an image can be taken of virtually anyone without gaining consent, and then be posted onto the internet for anyone to see. Unauthorised and unconsented images are being posted on the internet everyday and because it is so easy to do, this ethical issue is hard to keep under control.
Digital cameras are being used in many professions in today’s society and Occupational Therapy is one of them. In my first placement which was community OT, i observed digital cameras being used in various ways such as to show examples of equipment, damage to equipment, different techniques for transfers and seating of a client and an injury attained by a client (e.g. pressure sores, bruising from equipment). These images were consented by the client and their family to be taken and to be put in the clients file for use of evidence, as well as the clients’ face not being in any of the images.
Flickr.com have two main goals that they are trying to achieve through their sight, these are to enable people to create a blog of photos special to themselves and to have the choice over who can view their images. This means people may have preference over who can view their images weather its everyone in the world or just close family and friends. The other goal is to advance the technology of organising and viewing digital images, to make it more simpler and easier to manage personal digital images (flickr. Com)
Photobucket.com is another photo storage website that enables people to upload, store and organise their photos and to enable the people of their choice to view these.
Optical zoom uses the cameras lens to bring the target image closer. Digital zoom is not technically a zoom however, but it crops part of the target image and the enlarges it to fit the screen. The more digital zoom used, the worse the quality of the image will get (Photoxels, 2010).
