Here i have been experimenting with layering images. I began with a found image of a city scape, i cloned parts to create a busier images for example i cloned the tall tower a few times to add more depth etc to the image.
I then layered images i had taken of graffiti in a warehouse i found. I think the graffiti layered emphasizes the urban city feeling, I changed the opacity, curves and shadows and highlights in order for the graffiti to show through in random areas.
