I came across a website http://robcubbon.com/images/montage-girl.jpg and found a tutorial on how to create this image using layers and the mask tool, which i thought would help with my London cityscape photos. This technique was useful as it teaches how to overlap the background into the foreground and how to experiment with transparency.

I have looked at advertising campaigns by Nike to see how they have used Guerrilla advertising to promote their brand. Their main campaigns feature athletes mainly to advertise Nike trainers. 

I have collected and researched into Guerrilla Advertising to see how other campaigns have used logos in effective ways and used them in different environments and surroundings. My next step is to look for designers that have used cityscapes and collage in their work so that i have a clear idea on how to use my photos from London.
