The Canon EOS M6 Mark II, a Model, and a Lamborghini Huracan
The background typically consumes a large portion of the image and what it looks like matters. When the background is a bright red Lamborghini Huracan, the background begins to vie with the subject for attention, at least for us car guys and gals.
In this scenario, I gave the M6 II's AF system full control, selecting servo AF mode with face and eye detection. With the camera very impressively handling the task of following the model's face and eyes, I could concentrate fully on composition and that was especially helpful when shooting in awkwardly low positions such as this one.
