transform the supplied 3d screenshot into a photorealistic studio product photograph treat the screenshot as fixed geometry the composition contains four separate solid oak bowls placed closely together edge to edge two square bowls with circular recesses at the back left and front right and two rectangular bowls with elongated recesses at the back right and front left each bowl is an independent wooden slab preserve the exact arrangement and all dividing lines from the screenshot as narrow visible physical seams between separate objects with subtle shadow inside the seams these are not engraved lines or grooves in one large board do not merge the four bowls into a single object or add a shared base preserve the exact silhouettes proportions thickness recess shapes depths and camera perspective each slab has straight vertical outer sides a flat bottom and a flat upper surface surrounding a smoothly curved concave recess keep a constant thickness with identical top and bottom footprints no tapered sides raised rims bevels or additional edge rounding material natural solid oak with a light warm tone fine pores and subtle characteristic oak rays each bowl has its own distinct wood grain use different natural grain patterns spacing and subtle tonal variations for each of the four pieces while keeping them visually harmonious no repeated or cloned textures grain must stop at every seam and must not continue across neighbouring bowls on each elongated bowl the grain runs parallel to its longer side within each individual bowl maintain natural grain continuity from the flat upper surface into the milled recess show appropriate end grain on exposed cut edges fully matte finely sanded surface with a natural oak appearance no glossy varnish polished reflections or bright specular highlights the interiors are smoothly finished with only extremely faint cnc milling toolpath traces barely perceptible on close inspection no pronounced rings ridges or rough texture place three walnuts in the front right circular bowl only leave the other three bowls empty neutral light grey seamless studio background soft diffused lighting and gentle realistic contact shadows all four bowls fully visible and sharply in focus no additional props text or logos highest priority preserve the original geometry and clearly communicate four separate wooden objects with four independent grain patterns
