Finding My Way In The Dark

Trying out this new paper Terra Skin I went to dark, I had laid down a few layers of ink and was drawing into it and when it dried I had to stand at an angle to the piece to see the marks. The camera wasn't to happy either but I was hoping that by playing with the darks and shadows in photoshop I might find what I knew was there.

Really, there is something there,  38, x 24 in, ink on paper, 2014
