First of all my goal for this picture was to improve the lighting, since it was a bit dark. For this used a layer using curves to input a higher setting of white light. Then using the levels layer, I was able to change the pure white to brighten up the picture a bit more. I also used a cooler filter in order to get rid of the orange light on the white structure. Last thing, I used the dodge and burn tool to darken the cables, and also tried to bring out features of the picture.
