lovely illustration, and the great thing is that it no doubt "shows" more than the original photo. makes one think - well one is always thinking - about this thing called photography.
Done in Photoshop. Took a black and white version of the image into PS. Turned that layer into 'Find Edges' (i think) then brought in a colour version and mixed the layers using Multiply or something for the colour. Then I added another layer of the paper texture. Took a while playing about with those elements to get it like this.
