Fotomuseum Winterthur Director Nadine Wietlisbach, supported by Diana, guided a private tour of ‘Color Mania – the Material of Color in Photography and Film’. The group were taken through the exhibition, illustrating the development of colour in photography and film from the 1840s through to today – with analogue film documents, glass slides and film strips.

Standing in front of his large-scale work, ‘Lycopodium’ (2014), Swiss artist Raphael Hefti shed light on the elements of experimentation and chance in his practice. Explaining his process of scattering spores of a flammable moss onto unexposed photographic paper, causing the powder to catch fire – he then captures the reaction in the form of this intensely coloured photogram.
