Shooting directly into a light source is the fastest way to ruin a technically correct photograph and the slowest way to make a memorable one. The RF 50mm f/1.2L USM handles the contradiction better than it has any right to. The technique is contre-jour — French for “against the day,” meaning your subject is between you and the primary light source. The light halos the subject, separates them from the background, and collapses foreground detail into silhouette or near-silhouette.
