Prompt
16:9 wide conceptual photograph composed as a soft-edged artwork slice fully inside the frame with a clear transparent margin on every side; outside the slice the surround is fully transparent (real alpha channel, alpha = 0, not white, not colored, no checkerboard pattern), and the photograph fades at its rim into transparency over a short, even falloff.
At the heart of the slice, seen from the edge of a small weathered wooden pier, the open ocean stretches unbroken to a clean horizon under soft daylight and fills most of the slice. A single glass pipette hangs suspended in the upper part of the slice, tip pointing down, releasing one small clearly visible droplet that falls in mid-air high above the water. Far out on the surface a single spreading ring of pale foam marks where a previous drop landed, and the droplet, the pipette and the ring all read tiny against the immense calm sea, the wide emptiness between them carrying the scale.
Cool marine palette: deep blue-green water, pale hazy sky, transparent gray glass with one thin bright specular along the pipette, warm brown pier boards in the lower corner, the lone ring a small pale foam circle. Deep perspective, soft diffuse daylight wrapping the scene evenly.
