Using Art to Understand Forests
Ever since Steve Goddard, KU’s Spencer Art Museum, introduced me to Sunprints during our 2011 field class at the CICRA Biological Station, I have incorporated this art/science activity with subsequent classes. Sun-printing, developed by 19th century artists, uses the sun’s UV rays to make prints of objects on photographic paper. [UC Berkeley sells convenient kits].
After a morning of tough high-elevation hiking and a rich lunch of quinoa soup, we needed a quieter diversion. My kit had 15 sheets, enough for my KU students as well as others conducting research here. Each person collected some leaves and flowers and spent a few minutes designing their layout. Then we got to “printing”, essentially exposing the plate to sun for ~4-6 mins.
The end-product is beautiful and frame-able. Indeed, some appeared in our 2012 Spencer exhibition, http://www.spencerart.ku.edu/exhibitions/39-trails.shtml. This fun art/science exercise opens various discussions, e.g., about sunlight traveling down through forest layers* and leaf morphology**. No winner of our competition was selected since we could not agree on a single most beautiful plate from so many.
