A scanner can be used to digitise images.They’re similar to a photocopier but they make a digital copy instead of a physical copy. You can scan your printed photographs onto the computer and modify them in some way on one of the image editing software such as Photoshop or Gimp. Using a scanner will benefit graphical work as it allows the user to input images from an external source into a computer and modify them. If the designer had hand drawn an image, they can use a scanner to replicate the image on the computer where they could make changes to it, which they may not be able to do freehand as it could be too risky or compromise the quality of the graphics.
Once scanned in, an image or drawing can be edited in graphics software like Photoshop to add effects or colour. Thus, scanners can impact digital graphics by assisting in produce quality graphics.
