I drive past a half dozen school buses on my way to work, so this was a natural. I used six or seven solid color adjustment layers to color various parts of the bus and its interior, playing with the opacity and blending mode (mostly 'color') until I got the effect I wanted. I used the layer masks and high magnification to control where the color went. I repaired a number of defects on the bus -- added a hub cap, filled in damaged areas and so on. The ivy wall is from a stock photo. The asphalt was made from a layer filled with noise and then the render lighting effects filter. The font for the fictitious school district is Arial.
