They have been a massive step up from normal cameras, for example, you can view the image you’ve taken seconds after its been taken. The quality of the image is a lot better quality and you can also zoom a lot further and clearer than older cameras. When taken they can be immediately uploaded to a computer which allows them to be viewed on a big screen instantly. Limitations They are quite expensive which can be a problem but you can store lots of images on them. People who don’t have access to a printer would find it difficult to get copies of their which photos, so the old fashioned way of taking the image reel to a shop gives you copies may be a better method for some.
