(This class is given in french) Attracting and keeping attention is the art of photography. A single subject, a strong subject... and an environment that enhances it well, that's what composing an image is all about. All elements are important. 

Even the void! Yes, of course, we will describe the rule of thirds, but there are situations where the center is the most logical place to put a subject! Or right off to the side! Composition lines, shapes and "windows", 5% exception, contrasts, foregrounds, all these elements will allow your images to have more impact, and that's pretty much always what we look for in photography.
