LIGHTING
Well-lit product with lighting that emphasizes texture and important details. Rich shadows, possibly motivated ones to imply window lighting or other defined shadows.
woods
Closed-grain woods, satin or matte finish. Not rustic, but refined.
stone or concrete
Lots of choices here in terms of color and texture. I’d suggest keeping it simple, without veining, so the product shines.
metallics
Nothing overly shiny, but subtle and natural shades add a touch of refinement.
texture
Fabrics (layered or not) or textured paper move away from an actual environment into something a little more abstract.
solid color
With proper lighting to show a gradient, simple color can be rich and elevated.
