Digital Photography

“A new technology is rarely superior to an old one in every feature”
Digital photography has changed the world of photography. You no longer need to develop photos in a dark room, it is more cost effective but the photo quality is not the same and you also lose the possibility of developing techniques that can be done with film cameras. Digital zoom is also a poorer quality of zoom. Saying this you can perform many other features with a digital camera.

Some of the ways that digital images can be stored transferred and manipulated using other communications technology include:

Stored on memory stick
Uploaded to computer/ Laptop
Then transferred onto -CD
-DVD
-MP3 etc
Uploaded further onto web pages, blogs etc

Ethical issues can arise with the use of digital photography. One example of this is with social networking sites such as Bebo and Facebook. Anyone can upload photos of you onto the net. Informed consent is not required and this can create ethical issues.

On my occupational therapy placement which was in a paediatric setting digital photography was used as an educational tool. They would take photos of certain events that took place and then would have to re create the sequence with the photographs.

Digital vs optical zoom
Optical zoom uses the optics (lens) of the camera to bring the subject closer. Digital zoom is an invention of digital video cameras. Digital zoom is not really zoom, in the strictest definition of the term. What digital zoom does is enlarge a portion of the image, thus 'simulating' optical zoom.

A megapixel (MP) is 1 million pixels, and is a term used not only for the number of pixels in an image, but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays.
