Create a highly detailed 4k image of a physical sculpture of a tree trunk with branches extending into holographic foliage. The holographic leaves should change colors and shapes as viewers interact with the sculpture using AR technology. Artistic style should be a mix of realism and digital futurism, using digital painting as the medium. Use a medium telephoto lens with an aperture of f/4 to create a balanced depth of field, focusing on the transition between the physical trunk and the digital foliage. Lighting should mimic natural daylight, with soft shadows to highlight the textures of the tree trunk and the ethereal glow of the holographic leaves. The background features a minimalistic gallery space, while the foreground includes the detailed tree sculpture. Focus points include the intricate textures of the tree trunk and the dynamic, colorful holographic leaves. Apply HDR effect to enhance the details and colors, and use color grading to emphasize the natural tones of the tree and the vibrant hues of the holographic elements. Add a light leak effect to create a sense of magic and interactivity, and use sharpening to highlight the intricate details.
