"Those visuals were hand crafted through a unique process using paint, light, chemicals and pressure on Polaroid instant film. The color versions are full of vibrancy, perfect for a variety of projects, like packaging design, concert posters, album art and more. The black and white versions are stark and moody and would work great as overlaid textures for your design."

Thanks to Chroma Supply for this unique collaboration !
