On May 2, 2015, Constanza Isaza Martínez, Andrés Pantoja, and Melanie King were commissioned by the Wellcome Collection and UCL to make a gigantic Cyanotype for their ‘On Light’ event. The cyanotype measures 7.5x15 metres, and broke the previous record for the largest cyanotype ever made. More information can be found on Constanza’s blog
