The giant on one of my school's building is me! working on this exercise I figured that using a green screen to mask people for a still image is much more difficult, this is mainly because of all the green spills to remove from the person's photo. After doing this, I used the normal elements of compositing to put togheter me, my teacher and the background picture, I desaturated the photos of us, fixed the lighting a little, resized, masked, designed some shadows etc... I made the lightning using a photoshop plug in.
