Episode No. 172 of The Modern Art Notes Podcast features artists Liz Deschenes and Alison Rossiter.

The Walker Art Center is now exhibiting “Liz Deschenes: Gallery 7.” The show is a year-long installation of new work, including new photograms and pieces informed by the science of art conservation. Deschenes expects the photograms in particular to change slowly over the course of the year the show is on view. The installation is named after the Walker gallery in which it is installed. On the occasion of the exhibition, the Walker has opened up a near-floor-to-ceiling window that soaks the gallery — and Deschenes’ light-sensitive works — with natural light. The show was curated by the Walker’s Eric Crosby and will be on view through November 22.

Deschenes is one of a number of artists exploring how to make art out of photography without taking pictures. With winter weather impacting our taping schedule yet again this season, on the second segment, we’ll hear a conversation I had last year with Alison Rossiter. She uses expired photographic paper and liquid developer to make abstractions that reveal the history of the paper she uses. Rossiter will be showing new work at New York’s Yossi Milo Gallery in an exhibition titled, “Paper Wait.” It will be on view from Feb. 26 through April 4. Also, look for her work in “Process and Abstraction” on view at Cleveland’s Transformer Station through May 2, and in upcoming exhibitions at the J. Paul Getty Museum and at the National Gallery of Art.

Air date: Feb. 19. 2015.
