How the image is captured

When an image has been taken on something like a camera it must be converted into a file format which can be read by a computer, making the image digitalized. When scanning an image it is automatically saved as a bitmap image.

There are many ways and formats for capturing image data. This technology is constantly improving and evolving: Digital Cameras, Scanners, Tablets

Digital Cameras

These can be used for multiple of reasons, taking pictures, videos and much more. Camera capture images or videos which then get saved into a digital format which can be opened onto a computer and edited if the user wishes. Some new cameras can upload pictures to the internet while some have Bluetooth which can be used to send pictures as well as short videos to another Bluetooth device. Most cameras still have a slot for a SD card where all the data will be saved on, this can then be removed and inserted into the user’s computer.

Scanners

This can be used to scan documents on to a computer, the document will then be turn into a digital image in different formats (depending on the scanner settings); such as PNG (Portable Network Graphics) which is a bitmap file format. There are different kinds of scanner such as a rotary scanner which is used for quick scanning of documents.

Tablets

A tablet is a device that you can plug into their computer or laptop and then draw images on the tablet screen to see them appear on the screen. Artists primarily use tablets because it is a simple way to 'draw into' a digital device. Tablets with screens are available, allowing users to see what you're drawing without having to look at the screen.
