Realistic product photo of a drink in the style of advertising from the 80s. Natural light, soft morning light with haze. Realistic image from three plans. Background: sky with clouds. Medium shot: a whiskey glass is floating in the sky among the clouds. The shape of the glass is minimalistic, without edges, handles or legs. The glass is filled with deep black cold brew with a layer of thick, creamy foam that bubbles. A drink without ice, straws or other elements. The glass is foggy with dew on its surface. There are several clouds in the foreground that slightly obscure the glass of the drink.
