Shallow clear water ripples around the base of the stone, and a few drops bead on the glass. Soft mist hangs over the stream behind, where out-of-focus ferns and birch trunks glow pale green and gold. Low, warm sunrise light comes in from the left, throwing long soft shadows to the right and catching a bright glint along the bottle's edges. Replace the dark backdrop entirely. Photorealistic product photography with crisp detail on the glass and the fig's seeds, natural colours, and no text or labels.",
