Architecture photography, user experience design and visual design - Jerome Bertrand a.k.a. Prosper Jerominus


Next to designing, teaching and coaching user experience (ux) and user interface (ui) design, Jérôme Bertrand (artist pseudo: Prosper Jerominus) is creating art photography and mix media that shape and rise the eye.

As a lifelong practitioner, designer, and artist, my focus is primarily on architectural and societal subjects, with a particular interest in abstract art and figurative documentation.

Recently, I have begun to explore the theme of nature-culture in my visual work. Through this work, I examine the impact of human-induced pollution on the natural landscape, not as a means of inducing guilt, but rather as a tangible and open statement about human desire.

Dear pollution… I would like to.., I love you.., I miss you… etc.

Video documentary

Master in architecture photography: Lucien Hervé

My biggest inspiration has been working and learning from a great friend and guide, the french-hungarian  architecture photographer Lucien Hervé (1910-2007). This has been a very deep joyful learning experience for me with ever spirited guidance form Judith Hervé.

I have produced and directed a short documentary film in 2013 about Lucien Herve’s work with modern architect giant Le Corbusier in the Indian city of Chandigarh (1959). Montage by Beatrix Günther.
