Stokes croft collage

this is a collage me and a few class mates created as a project. we spent about half a day gathering images of street art in stokes croft, the idea was to gather lots of images together and make them look right together in an image, also we had to give the collage a sense of depth. in order to give  the sense of realism/depth i added the brick wall over the top reduced the opacity and change the layer style to 'overlay' giving the feeling of one big graffiti scene and not lots of small ones. then to add more depth i added the security camera to the wall. all this was done using Adobe Photoshop.
