A Conservation and Restoration Laboratory:
AV Preservation by reto.ch

This farewell event will mark the end of nearly twenty years of paramount photochemical and digital services provided by AV Preservation by reto.ch.

We always had a particular commitment to the dissemination of audio-visual conservation and restoration techniques among friends, colleagues, scholars, students and any interested person. We also invested a large amount of time and money in open-source projects, which we believe are beneficial for the archival community.

What and How

A lecture by Joshua Levy, Michal Cohen and Reto Kromer with screening of some of the highlights, followed by an informal Q&A session and light refreshments.

When and Where

The plan is to offer an in-person event with webcasting, hosted by the Lichtspiel in Bern on Thursday the 29th of June 2023, starting at 5 o’clock sharp here in Switzerland (that’s 15:00 UTC). Of course, this might change depending on the global sanitation emergency, the global climate emergency, the Third World War “et cetera et cetera et cetera”.


  • Just in case, we are quoting here the king [Yul Brynner] in The King and I by Walter Lang (USA 1956).
