In 1984 he developed a specific holographic technique for chromatic control and began the regular production of technically very elaborate works.

In some of his projects in this field he worked in collaboration with other Brazilian artists and poets interested in holography (Augusto de Campos, Décio Pignatari, Julio Plaza and José Wagner Garcia).

A year after his death a retrospective of his cinema and video works was held at the 9th International “Videobrasil” Festival - 1992 in São Paulo.

Holographic poems by Augusto de Campos and produced by Baumstein were purchased by the "Centre Régional des Lettres de Basse-Normandie" in France and in 2007, the holographic poem REVER was exhibited at the exhibition "Concrete Poetry - O Projeto Verbivocovisual" in Tomie Ohtake Institute (São Paulo) and at the Palácio das Artes (Belo Horizonte).

Videcom kept the activities of his holographic laboratory until 2007 when all the equipment was donated to the Optical Lab from the University of Campinas Physics Institute under the responsibility of Prof. Jose Lunazzi.
