12 hours of exposure in this lumen print, a lettuce leaf dried under the sun in contact with the black and white outdated paper.
I love this image, the veins, the tones. Reminds me, don't ask me why, of the first maps of Mars.
If you like this image or the others maybe you are interested in buy a copy, there you can do it if you live in Europe: http://www.artflakes.com/en/shop/yourmung
A hug.
