Beyond these references, Andrews’ uses the technique to, at the same time, evoke the alchemy of vision and break its mechanics down. As a result, Andrews creates works that “hover at legibility.” “The pixilation or dot matrix completely obscures details, making specifics impossible to see. We can't grasp the full picture.“ The series of rubbed-crayon
Chroma dots Chroma dots Chroma dots are visual artifacts caused by displaying an unfiltered analogue color video signal on a black-and-white television or monitor. They are commonly found on black-and-white recordings of television programs originally made in color. Chroma dots were once regarded as undesirable picture noise, but recent advances in computer technology have allowed them to be used to reconstruct the original color signal from black-and-white recordings, providing a means to re-color material where the original color copy is lost. Analogue color video signals comprise two components: chrominance and luminance. The luminance component describes the brightness of each part of the
