In the past, images were made using the mosaic technique; today we do it with coloured dots called pixels. Pixels only come in 3 colours, and they are different depending on whether we are talking about monitors or prints.

The audience will get to interact with the event leader to find out how images are created using the mosaic technique, and how the way we create an image using coloured dots has remained practically unchanged even today. Using photographs and videos, we can analyse everything about how an image is made, and how it can be optimised for printing or projecting. We will explain primary colours, and the techniques known as additive and subtractive synthesis that make it possible to display all colours on screen or in print. We will explore the mathematical, physical, and perceptual rules that regulate the observation distance in relation to pixel density, to avoid having a TV set that is too large for our room, poor printing, or a smartphone screen with definition that is too low to get the best out of our photographs.
