For the Touch Me series, I started by digitising small areas of a set of old photograps and negatives found discarded on a street in Lisbon. After blowing up these images, each print was silk screened with black thermochromic ink.

This ink is heat-sensitive and turns transparent with temperatures above 25ºC. As such, the prints appear very dark. It is only by warming their surface with the heat from our hands that the images underneath are "developed", and we can see the hidden image. After a while, the ink will revert back to its original colour, thus preventing us to see what's underneath.
