4.3 Pixelated Images

Liquid crystal display or LCD digital screens are made up of tiny liquid crystals (LCs) that shine either red, green or blue light (RGB). Digital images also use pixels, but use a wider palette of colours. Internet images such as jpgs or gifs work with 256 web colours to create all the images, illustrations and web content online. Pixels work on a simple grid format
with lines of equally-sized squares. The blending of the colours takes place visually, with pixels being too small to be easily seen by the naked eye.
In the early days of digital images pixels and the rough edges they create were more evident and consequently more a part of the visual language of computers. Certainly early computer games had this very squared, pixelated feel to them and many artists and illustrators used this way of working to represent the digital.
Using a grid format of pixels, create a series of illustrations that explores your relationship to digital technologies. This might be a love or hate relationship, a document of all the forms of technology you engage with, the games you’ve played or pixel portraits of your friends on Facebook. Be imaginative with how you approach this.
You may want to work on graph paper or create your own grid on the computer or by hand. The size of your pixels is up to you. For example the animation DEADLINE (available via YouTube) uses post-it notes as pixels. But stick to the rule of only using one colour per square. You may want to limit your palette or perhaps work in full colour.
