Craft a realistic portrait that captures the essence of an elderly indian monk's wisdom and tranquility. the intricate details of his flowing white beard and serene expression should reflect a lifetime of spiritual devotion. set against the backdrop of a majestic tree, its branches reaching upward, create an atmosphere of contemplation and connection to nature. employ a full-frame mirrorless camera with a sony fe 85mm f/1.4 lens for sharpness and background blur. use diffused natural light to enhance the monk's features and the tree's texture, and set the aperture wide open at f/1.4 to achieve a shallow depth of field. a color temperature slightly warmer than neutral will evoke a peaceful mood. aim for a 1080p resolution to ensure clarity and detail in the final image. compose the shot within a 16:9 aspect ratio, allowing the monk and the tree to share the frame harmoniously. the outcome should be a heartfelt portrayal of spiritual reflection and the connection between man and nature.
