“A new technology is rarely superior to an old one in every feature” This statement in relation to digital camera technology could mean that the newer devices that are released are not always better than older models and that many people would prefer to stick to the older ones (they may find the older ones more reliable)

Some advantages of digital cameras over film based cameras are that with digital cameras you can delete images that you are unhappy with and you don't always have to pay for film. Disadvantages of digital cameras over film cameras are that you may take shots that are more carefully thought about rather than lots of pointless ones and also you cannot accidentally delete the wrong photograph which can happen on digital cameras.

Images can be transferred to computers, t.vs cell phones, and many other devices, they can be stored on devices such as external hard-drives and flash drives and can be edited and changed on computers with programs such as photoshop then uploaded to websites.

Images are constantly being captured by web cameras, cell phones, cameras etc. Ethical issues that may arrise from this is people may be captured in images that they don't want anybody to see or somebody's work may be captured and distributed that they don't want others to see and is copyright.

Digital zoom is when the camera 'crops' the image to make it closer with sacrifices the quality of the image. Optical zoom is when the lens magnifys the image and image quality is not lost.

Images are made up of many many tiny squares of colour, these are called pixels. The higher the number of pixels in an image the better quality it will be. A megapixel is equal to one million pixels.
