Meghann Riepenhoff Self-published artist book by Guggenheim-award winning photographer Riepenhoff. Eluvium is the residual deposit of soil, dust, and sand produced by the wind. To create the images in this series, I cast sand on sheets of light-sensitive paper in the dark. I then spoke, sang, laughed, screamed, cried, and breathed in almost touching proximity to the paper, my actions moving the sand into formations. I exposed and processed the paper, titling each image after what I said or did to create it.
