Prompt
An irregular black slate sits diagonally on a dark stone counter, holding six pieces of sushi: tuna, sweet shrimp, mackerel, white fish, salmon, and one cooked shrimp with the tail on. Wasabi, pickled ginger, and a small purple herb sit in the middle. Steam rises off the fish and catches the side light. Light from the upper left, hard but narrow, lighting only the sushi and the slate edge; the background is nearly black, with a dark bowl falling out of focus. 50mm, f/2.8, clear texture: rice grains, fish fiber, slate pores. Appetizing photography, not a flat illustration. Wide frame, the slate running from lower left to upper right. No menu text, chopstick logo, watermark, or garbled lettering.
