The scene lighting is {argument name="lighting" default="The cool blue underwater light on the left, with a warm amber reflection on the brass edge."} Add to the image{argument name="atmospheric elements" default="Suspended bubbles, floating particles, and murky underwater mist"} The overall atmosphere is tense and mysterious; the eyes faintly visible behind the glass should convey {argument name="emotion" default="obsession and fear"} It features shallow depth of field, macro-level detail, cinematic contrast, gradation of cyan and blue tones, a glossy, wet surface, and a volumetric underwater atmosphere. It contains no text, no watermark, and uses a vertical 4:5 composition.
