Prompt
A single ceramic coffee cup sits as the primary subject, positioned in the lower center-right third of a vertical 2:3 frame so the cup base occupies the lower third and the steam rises into the upper two-thirds of the composition. The cup fills roughly one-quarter of the frame width, creating generous negative space in the left third for a balanced poster-style layout. Morning light from the upper-left casts a warm amber rim and soft side-shadow across the cup and a narrow wooden tabletop, producing gentle specular highlights on glazed ceramic and a matte wood grain texture. Steam curls upward in delicate translucent tendrils with soft edge definition against a softly graduated neutral background that occupies the upper 60% of the frame. Focus is shallow with razor-clear rim and lip detail and progressively softer texture toward the background to emphasize depth. Render as polished product-photography with naturalistic tonal transitions, subtle film grain, and restrained contrast for cozy, serene mood.
