In 2010 Vilvoorde once again becomes the inspiration for the artist who, this time, instead of photographing only tree trunks or sections of plants, takes a step back to contemplate the wider dimension of the forest. Fog, Winter, Humidity and the Forest Floor are the ingredients of Forest in Negative which years later will transform into a wider collection of varied mountainous areas as Snow in Negative, where he will experiment with photographing the snow in the Benasque Valley, in negative.

Flowers in Negative, without meaning to, becomes one of the most valuable collections for the architects and interior designers who work hand in hand with Marcos.
