Yeastograms in the cover and featured in the book: Art as We Don’t Know It.
Current Project: Living Images, in Portfolio.
My artistic research explores my relationship with microbes and how environment is affected by my actions. I also study the perishableness and disappearance of matter.
I produce living images with raster images, uv-light and yeast. After exposure (aprx. 48h) I photograph the outcome.
