Foam Line Theory

A macro close-up shot of freshly brewed espresso with a dense layer of crema on top and dark coffee bubbles forming a sharp line across the middle. The bubbles vary in size, creating a textured, organic pattern that resembles abstract geometry. The colors transition from rich amber at the bottom to deep black in the middle, and light golden foam on top. The lighting is soft but clear, highlighting the surface tension and reflective nature of the bubbles. Minimalist, tactile, beverage macro photography aesthetic.
