Mustapha Azeroual confirms here his ability to print with gum bichromate, which he develops in polychromy and with a rather unusual colour palette, partly composed of fluorescent pigments. The ACTIN series brings together photograms, photographs without a camera, in which each work is the synthesis of several superimposed prints. Layer after layer of photosensitive emulsion, through a series of overlaps, covers and successive openings, Mustapha Azeroual inscribes the traces of his gestures on the paper. Shapes are revealed in the actinic light of the UV and accumulate in increasingly tenuous pigment gradations.
Returning to the source of photography, considering light not only as a vector of the visible, but for itself. Here we find a leitmotiv of the artist's work, analysing light as a sensitive material and developing forms that embody it. In this research, colour is present as never before in his use of gum bichromate. A new inclination that also seems to be influenced by the singular luminosity of Morocco, where the artist has installed his laboratory for two years (2018-2019).
