Richard Foster style use product light refraction and color, low angle camera. Use light to create geometric shadows and staggered lighting. Use a glass plate to create a reflection. He was a master at using light to create different shapes of color light. The main color is very prominent. Good at using glass products to bring a light reflection and refraction of the different light effects. I think his works are very textural and very commercial. The products themselves are very textured, and the background is to reflect the product itself. There is no extra light or unnecessary things around the products, only simple light and color and his creativity are formed.
As you state, its not about fancy props or anything that might distract from the product itself. Foster makes the photos alluring by the use of composition.
