On this occasion, these images are from a “catrin” photo shoot, for which Angel, who was my student a few years ago, served as my model. I didn’t teach him anything about photography, since I’m a chemist and Angel was an industrial engineering student. I remember I just mentioned to him once that I needed male models to develop this series of portraits, and without giving it much thought, he agreed. The result was quite good; it was one of my first sessions in a space large enough to call a studio.
