"A new technology is rarely superior to an old one in every feature".
In relation to digital camera technology this quote explains how although the new technology of digital camera have become widely acceptable over the traditional film based cameras, they are not completely superior to the older model of camera. The tradition film based cameras have elements that cannot be replicated in digital cameras.
The pluses of a digital camera is that they are multifunctional. Not only able to take photographs, but also record sound and videos. They allow a wide distribution of images onto other mediums and allow the photographer to manipulate and edit the images. Yet digital cameras come with some disadvantages as well. Including, nonpermanent storage of images that eventually can start to lose data, an additional step of having to download images before printing, additional devices such as a computer, printer, cables etc that have become dependable technologies to film. They can also be expensive and the technology is being overtaken fast. And digital cameras are unable to give the element of surprise experienced with traditional film based cameras.
Digital images can be saved to communication technology such as cameras, CD, onto computers, handhelds, ipods and camera phones. The images can be manipulated using these devices or additional programs that can be loaded onto them.
With the prevalence of image capturing devices ethical issues arise especially around privacy, anonymity, storage, access and manipulation of information.
Digital images could and are being used in occupational therapy to take photos on location of houses that are being proposed for adaption to be used in reports and to be given to builders for quotes. They are also being used to take photographs of clients postures for applications for sleep systems, seating and wheelchairs. They are also being used in interventions for example as visual cues for clients in specific activities.

Digital Zoom and Optical Zoom
Optical Zoom - lens changes focal length and magnification as it is zoomed. Image quality stays high throughout zoom range, retaining clarity.
Digital Zoom - simply crops an image to a smaller size, then enlarges the cropped proportion to fill the frame again. This expansion results in the loss of quality and produces a blurred image.
Megapixel
Picture elements more commonly referred to as pixels are the millions of tiny squares that compose images.
A megapixel is made up of 1 million pixels. The megapixel refers to how many individual pixels go into making each image.
