Poster Design Principles To craft a black-and-white poster out of this image that conveys a sense of conflict, I would focus on capturing the tension that already exists within the frame—the interaction between the journalists, the scene they are documenting, and the elements of technology they wield. In converting this image to monochrome, I would emphasize high contrast to bring out the stark differences between light and shadow, making the figures appear almost as silhouettes against the twinkling city lights.
