Create a gloomy and unsettling atmosphere as you attempt to photograph a tiger lurking in the shadows. The lighting should be dim and eerie, casting haunting shadows on the tiger's form. Use a narrow aperture to obscure details and create a sense of mystery. Instead of showcasing the tiger's magnificence, emphasize its stealth and danger, capturing it in a less than flattering light. Enhance the overall grimness through post-processing, with desaturated colors and high contrast. Emphasize the intensity of the tiger's gaze, evoking a feeling of unease and vulnerability in the viewer.
