" A new technology is rarely superior to an old one in every feature"
In relation to digital camera technology, it is constantly changing and upgrading but it is not always for the best as older cameras may be seen as more reliable,they are still around and used today.
Some of the pros and cons of new digital cameras
PROS:
-can view the image straight away/don't have to pay to get the reel developed to view
-ability to share photos via the Internet
-can take up to 100 photos on a memory stick
-can edit and print of the photos yourself
CONS:
-sometimes its not worth repairing as parts can be expensive and may be cheaper to buy a new camera
-it can be expensive to buy the equipment/software required to print and edit
-they can be hard to use as there are so many different functions
-the zoom on the camera may not give you a good picture,resulting in you having to pay more for better zoom
Some of the pros and cons of older cameras
PROS:
-simple to use 'point and click'
-don't need to carry around a lot of extra equipment e.g. batteries/chargers,memory sticks
-its nice to have a surprise as you don't know what the photos will look like until they are developed
-the zoom is better
-good to have a physical copy of the photos to put in photo album
CONS:
-harder to buy as digital cameras are more common
-can only fit about 36 pictures at the most on 1 roll of film
-cannot edit the photos,so if they are bad photos due to bad lighting or something its tough luck

Digital images can be stored in a variety of ways,such as on Cd's, hard drives, memory sticks, they can be transferred using items such as Internet, fax, scanner,mobile phones. Images can be manipulated using software such as photo shop and equipment such as photo stations where you can crop, change colours and add special effects.
Some of the ethical issues that can arise as image capturing devices are so commonplace,there can be dilemmas around a lack of privacy as some people who's photo has been taken has not been informed what it will be used for,also things such as text messaging and emails can be sent to the wrong recipient which could contain confidential information.
Occupational Therapists are now using digital images for housing modifications, where a pic of the clients home is used if assistive devices or equipment are required. Videos and photos of a client may be taken during an assessment or intervention to monitor the clients deterioration or progress.

The difference between optical and digital zoom is that Optical zoom is known as 'true zoom' as it uses the lens of the camera to bring the subject closer where Digital zoom enlarges a portion of the image so it its bigger not closer up.
A mega pixel is 1 million pixels, 1 pixel is a small square of colour and when they are all put together it creates the digital photo.
