Tutorial 2: Digital Camera use and applications

“A new technology is rarely superior to an old one in every feature”. This statement in terms of digital camera technology relates to the fact that the camera is the same in terms of the purpose that it serves, it has merely been developed on to improve its quality of pictures, reliability of producing images and improving its appearance to be more compact and sturdy. Some pluses to digital camera technology are that you can delete the images before you print out the images and you are able to see what the photos look like before you have them printed, the images are more sharp and clearer to the viewers eye and the colors are much more vivid than they used to be. Minuses to the digital camera technology that you are less likely to have the film printed out - instead you just upload them onto a computer and images are easily deleted or forgotten about.

Digital images can be stored on the camera itself, transferred onto other devices such as a USB, computer, hard drive, DVD, website such as flickr or photobucket, facebook, bebo, emails. computer programs such as photoshop and iphoto can edit and manipulate the images to ensure that the photo is ideal and meets the users wants and needs.

The public websites of transferring and sharing files produce ethical issues because anyone is able to see the images, copy them from the websites and use them for their own purposes. This is an issue in terms of privacy and confidentiality because it is open for public use so anyone can look at them or take the images.
