Elegant food photography, early 20th-century style: A perfectly poached, light pink salmon fillet, skinless, is centered on a fine white china plate with a subtle gold rim. A generous, smooth, and glossy pale-yellow Hollandaise sauce (or a slightly fluffier Mousseline sauce) is artfully napped over one side of the salmon, allowing some of the pink fish to show. Beside the salmon, arrange a few thinly sliced, bright green cucumber rounds, possibly overlapping slightly. A single, vibrant yellow lemon wedge rests on the plate. A delicate sprinkle of finely chopped fresh dill or parsley is scattered lightly over the sauce and plate. The background is softly blurred, hinting at a luxurious Edwardian dining saloon with dark wood and crisp white linen. Lighting is soft, natural, and slightly formal, emphasizing the textures and freshness of the dish. Cinematic, historical, refined, appetizing.
