in class we discussed the difference between graphic programmes that use bitmaps ( adobe photoshop, brushes, procreate) and vectors ( Adobe Illustrator). Whilst bitmaping is a versatile graphic system for digital mainutplation, painting, drawing illustrating on a computer screen, using vectors which uses mathematical mapping to increase a graphic without losing any definition

Multiple layered image in procreate, st georges cathedral, southwark

this image was created using bitmapping, in procreate I imported, layered and manipulated multiple layers of mobile phone photographs taken from different angles. As a bit map it could be enlaged to possibly A1 but to increase it anyfurthur the pixel base of the image would deteriorate

I drew a Keith Harring dog in Adobe Illustrator, its Artificial Intelligence AI provided this version

Draw on Adobe Illustrator this vector based image can be enlarged without any pixel loss, it is the industry standard for sharing images to be used commercially, instructions can be given to robotic 3d printers and laser cutting machines
