This is a pretty standard photo retouch job. The client had this stock shot of an escalator but they needed it modified for their purposes. The image had been used in a layout and the client loved it so they wanted to keep as much of it as possible. They needed more bleed however and a wall to the right side. They also needed keep out signs. Below is their stock image.
Below is the image after I retouched it. I created the wall, signs and extra bleed in 3D and composited them in Photoshop.
