Paper Negative 1

I was doing a darkroom print one day, and I happened to leave a sheet of printer paper on my photo paper and I exposed the photo paper on the paper, I realised that the photo isn't going to appear, but what amazed me was that the light still managed to get to the paper and I thought that was it, because I thought paper was opaque, and wouldn't let light through, so that gave me the idea of the 'Paper Negative'. I printed out a digital photograph with inverted colours onto normal printer paper, and I used that as my negative, and this photo was the result of it, it turned out really well and what I thought was interesting was the grainy effect on the photo due, to the ink that was printed on the paper. As the 'paper negative' technique was so successful, I will plan to continue the use of this.
