Retro flash, a dark room and a veil. The interesting part is at the very end: this prompt has negatives, and they are not written as a list.
What it got: nearly all of it. The upright piano with its keys open, the frames and busts sitting in the dark behind, hands up holding the veil open, head down and eyes lowered, lace gloves, lace choker, pearl necklace. Flash on the face, everything behind it falling away underexposed. The only real drift is the wardrobe — “white lace wedding-style gown” came back as a lace bustier and a slit skirt.
The ratio landed, and it is first again. The prompt opens with the literal words Aspect ratio: 4:5 and the image is 4:5. That is now four entries pointing the same way: put it at the front and you get it, bury it at the end of a long prompt and you do not.
The negatives are a clause, not a list — and they held. The prompt ends “avoiding ordinary passport photo feel, overly clean studio shot feel, or plastic-looking veil”, and all three are avoided: the framing is not a passport photo, the light is a hard on-camera flash rather than a clean studio setup, and the veil reads like fabric with weight to it. Set that beside the one with a real Negative Prompt: block, where a list of twenty-odd words was mostly ignored. The difference may be that these negatives are attached to things already being described — the veil, the lighting, the framing — instead of floating in a list at the end with nothing to attach to. One run is not proof of that, so treat it as worth trying, not as settled.
One image this time, so there is nothing to say about what holds across runs.
