They Meet at the Waterline
A painterly mirrored film poster — with the reflection joined to its subject at a stated surface line, so it reflects rather than merely repeats. Five fields.


Two runs of the same template. The clearest demonstration of the offset rule. The figure joins at the boots, the stone stacks join at the waterline, and the crane - which stands well above the surface - has its reflection the same distance below the line as the crane is above it. Both runs exposed a fault in my own template rather than in theirs: the type section asked for a credit block in a lower corner that no field supplies, so both filled it in - one with garbled pseudo-text, this one with an invented glyph and the number 0524. The template now forbids corner text the fields did not give; these two images were made before that fix and still show it.
The reflection is attached: it begins at the figure's boots and runs down, and the sun returns as a long glitter path rather than a second disc. The reference run of this style flipped its whole scene and stacked it, leaving figure and reflection at opposite ends of the sheet with the title in the gap between them. Worth knowing: the wash changes what the format is - the source was a mirrored composition, and applying the joining law turns it into a scene with a real reflection in it.

They Meet at the Waterline
Produce ONE image, 2:3 portrait: a thickly painted scene reflected in a surface. Follow every line. Replace only the FIELDS block; everything after it is fixed.
First — do you have the fields?
If any field below still has braces around it, stop and ask. Put all the questions in one short message, and show the example under each one so they can see the shape of a useful answer. Wait for the replies, then draw. Never fill a brace yourself: a value you invented is a value nobody asked for, and it will look exactly as considered as the ones they did give you.
Ask in whatever language they are writing to you in. Translate the questions and the examples; do not make someone read English to tell you what they want.
The examples are only examples. If someone answers a question, use their answer; never fall back to the example because you prefer it.
If the fields are already filled in, ignore this and carry on.
Fields — replace these five lines only
- The scene, and what is in it: {a place, and three or four things}
- The subject, and how far above the surface they stand: {a person, and where their feet are}
- The surface, and where the line sits: {a reflective surface, and a height on the sheet}
- The title, and where it goes: {a title, and which half}
- The palette: {a cool range, and a warm range}
The joining law
A reflection is attached to the thing it reflects. That is the whole difference between a reflection and a copy.
There is one surface line, horizontal, at the height the fields give. Above it is the scene; below it is what the surface returns.
Every object touches its own reflection at that line. Where an object meets the surface — a figure's boots, a post entering the water, the hull of a boat — the reflection begins at exactly that point, with no gap.
Objects above the surface are offset by their height. A ferry standing off, well above the waterline, has its reflection equally far below it. The distance from object to line equals the distance from line to reflection, for everything in the picture.
A reference run of this style flipped its scene and stacked it: the figure stood in the lower third and the inverted figure hung in the upper third, with the whole middle of the sheet — and the title — between them. Nothing touched anything. It was two copies of a picture, one upside down.
Follow the subject down to the line. If the reflection is not attached at their feet, this rule has not been applied.
The reflection is not a copy
The lower half is the same scene returned by a surface, and it shows it:
- Darker and lower in contrast than the original, throughout.
- Vertically compressed — a little shorter than the thing it reflects.
- Broken by the surface: horizontal ripple bands run across it, displacing it slightly and increasing toward the bottom of the sheet.
- Detail is lost. Fine things — rigging, grass blades, faces — dissolve into shapes.
- The sun's reflection is a long vertical glitter path, not a disc.
It is never a clean flipped duplicate.
The scene
- Painted thickly: visible brush loading, ridged strokes, canvas tooth showing through in places.
- Warm light source low and behind, cool everything else, so the poster reads as two temperatures meeting at the line.
- The subject small, seen from behind, in silhouette against the light.
- Rough grasses or reeds may frame the outer edges of both halves.
Type
- The title in one half only, as the fields say — large, in a broad brushed or painted face, sitting in the sky or the water but never crossing the surface line.
- A short subtitle beside or below it.
- Nothing else. No credit block, no billing text, no date, no laurels, no corner marks. If the fields did not give you a line, the corner stays empty painted surface.
- Only what the fields supply — no invented festivals, laurels, studios or ratings.
Never
- ✕ a reflection detached from the thing it reflects
- ✕ a gap between a subject's feet and their reflection
- ✕ objects and reflections offset by unequal distances
- ✕ a reflection as bright, sharp or detailed as the original
- ✕ a perfectly flipped duplicate with no ripple or compression
- ✕ type crossing the surface line
- ✕ a sun reflected as a disc rather than a glitter path
- ✕ invented laurels, festival names, credits, dates or corner marks
- ✕ any text in a corner that the fields did not supply
- ✕ more than one surface line
The result
A picture with a real surface in it: one line across the sheet, everything standing on it joined to its own returning image, and a lower half that is plainly water rather than a second copy of the sky.
The whole template, in one piece. The steps below are the entire workflow.
How to use it
- Copy the whole template with the button above.
- Replace the five FIELDS lines. Always say where the subject's feet are relative to the surface — that is what the reflection is measured from.
- Paste it into any image-capable agent or model, in one message. One run returns the poster.
- Follow the subject down to the line before shipping. If the reflection is not attached at their feet, the picture is a flip, not a reflection.
What you swap
- The scene, and what is in it
- a sunset estuary — a plank jetty running out to the right, a line of mooring posts, a small ferry standing off, a low sun behind it
- The subject, and how far above the surface they stand
- a person with a rucksack, seen from behind, standing on the wet sand at the jetty's foot — their boots on the surface itself
- The surface, and where the line sits
- wet tidal sand with a thin sheet of water on it — the line two fifths up the sheet
- The title, and where it goes
- THE LAST FERRY across the upper half, with a small subtitle beneath it
- The palette
- deep indigo and slate above — burnt orange, gold and cream in the sun and its reflection
Before it runs
- A subject that touches the surface. Someone standing in shallow water reflects; someone on a distant clifftop has nothing to meet.
- Objects at different heights. Posts, a boat and a figure at three heights make the offset rule visible; a flat scene hides it.
- A title short enough to sit in one half. Anything longer will want to cross the surface line, which is the one place it cannot go.
When to reach for it
Film and festival posters, album art, anything elegiac. Templates in this style flip the scene and stack it, leaving the figure and its reflection at opposite ends of the sheet with the title in the gap — two copies of a picture, one upside down.
What changes
- One thick-painted scene reflected in a surface, in a warm-against-cool palette.
- A stated surface line where the two halves meet, with every object touching its own reflection there.
- Reflections offset from the line by the same distance their objects stand above it.
- A reflected half that is dimmer, compressed and disturbed by the surface, rather than an identical flip.
- Title and credits held inside one half, never crossing the surface.
Pairs with
- Bolted to the SkyA mascot built as real signage — a face on a plate, one wider name plate under it, and visible hardware holding both to the pole. Six fields.
- Cut, Not FilledA copperplate-engraved city poster in one ink — where every tone is line density, nothing on the page is a flat fill, and the bare paper is a shape rather than a margin. Six fields.
- Every Bar Is a MultipleA barcode poster in two colours — with the code built on a base module, guard bars and a numeral row, so it reads as a scanned object rather than a stripe field. Five fields.
