To begin, I have chosen a photo that I took myself when I was on holiday in Italy. I will use this photo because it doesn’t contain a direct light source (in this case the sun); it has a nice diffused light that we can easily match to the techniques I will demonstrate and doesn’t need complicated 3D geometry to get good results! In future tutorials, we will look at different lighting scenarios and more complicated images, but for now its important we start with the basic principals.
