Commission Original Treatment Illustrations That Answer the Missing Visual Question
Commission Original Treatment Illustrations That Answer the Missing Visual Question
An illustration earns its place in a treatment when it shows a relationship your references can't. Everything useful below follows from that: name the question first, separate fixed facts from open decisions, ask for the rough at the point where you can still change your mind, and only then talk about finish.
Before you send a brief, finish this sentence:
We can't show how ___
If nothing fills it, you don't have an illustration problem yet. Send the idea back for another pass, or go looking for reference. A commission is an expensive way to discover that the concept wasn't finished.
The missing thing is usually a relationship
Most requests over-specify objects and under-specify relations. An object can be photographed, bought, mocked up or found in a stock library by lunchtime. A relation can't. In practice the blank is usually one of three things.
Where something sits. The seating arrangement around a table, the distance between a speaker and an exit, the angle at which one machine feeds another. You can find photographs of all three ingredients and none of the arrangement.
How one state becomes another. A surface that was plain and is now covered. A room that was empty and is now full. The interesting frame is almost never the state; it's the change.
How two worlds meet. Something drawn next to something filmed. A diagram that has to survive being placed beside a photograph without looking like a mistake.
A quick diagnostic: if the missing thing is a fact — what the inside of a working biscuit factory actually looks like — that's research, not illustration. Original artwork doesn't establish what exists. It establishes what you mean.
The example this article keeps coming back to
This one is invented, for teaching. No illustrator was commissioned while writing it and no rough was approved.
A tile manufacturer is pitching a thirty-second spot. The product is a hexagonal matte tile printed with overlapping arcs in chalk, sand and deep green; the pattern repeats on a 600mm grid. The spot opens on a single tile sitting on a wooden kitchen table, under a cup. Over thirty seconds, the same material takes the table, then the wall behind it, then the room.
The team has two references, and both are good. One is a white-background product shot of a single tile. The other is an interior photograph of a finished tiled floor with a sofa and a window in it. Between them, they cover the beginning and the end. Neither shows the moment the table becomes the room.
So the question writes itself.
The question. How does one continuous tile pattern travel from a horizontal tabletop to a vertical wall — and out to a whole room — without the change reading as a cut between shots?
Fixed. Hexagonal tile, matte glaze, three colours (chalk, sand, deep green). The arc pattern repeats every 600mm. Joints stay visible wherever the surface is tile, including at room scale. At least one view shows the tile at true scale so its size can be judged.
Open. How the change happens. Where the camera is. How the change is broken down inside each of the three stages. What is in the room. How much of each colour appears and where.
Wanted. View A: a three-quarter view with the table's back edge and the bottom of the wall both in frame, drawn as three stages — one tile on wood, tabletop tiled, pattern crossing onto the wall. View B: a wide frame from seated eye height showing at least two walls and part of the ceiling.
Not needed yet. Light, glaze, surface finish, final colour.
That's a workable brief. The rest of this article is the reasoning behind its parts, because the parts are the transferable bit.
Fixed facts are the ones you can't be wrong about
Product facts are not taste. The 600mm repeat is a fact. The hexagon is a fact. "It should feel expansive" is taste. An illustrator can solve the second; they cannot guess the first.
When you fix something, say why, because the reason tells your collaborator whether the constraint is load-bearing. Joints stay visible not because joints are attractive but because a wall of unbroken pattern is a printed graphic, not a tile — the spot would be selling a product that doesn't exist. Given that reason, the illustrator knows which parts of the surface treatment are negotiable and which aren't, and can argue with you where you've confused habit for requirement.
This is also where most expensive corrections originate. If nobody states the joint rule, the illustrator draws a smooth continuous surface, everyone approves it because it looks better, and the finished image contradicts the product it advertises.
The open list matters just as much, and it should be generous. The illustrator's job is to propose how the change happens, not to execute your version of it in someone else's hand. If you already know exactly how it should look, you don't need an illustrator; you need a renderer, and you should say so.
Describe references by what they prove, not by who made them
The interior photograph is in the deck for one reason: at eight metres, you can still count the joints. That's the property worth pointing at. It does not prove the palette, the sofa, the camera height or the light, and the brief should say so in as many words. Otherwise the reference stops being evidence and becomes a target, and you'll get its furniture.
Which is the honest problem with "in the style of" plus a named living artist. Apart from putting your collaborator in an impossible position — asked to reproduce a recognizable body of work they didn't make — it isn't a brief. It's a guess at somebody else's problem-solving, and it doesn't tell the illustrator what property of that work you actually want. How much of an imitation you could lawfully use is a separate question, and it's also a worse one, because the answer doesn't help anyone draw.
Name the property instead. Usually it's three adjectives: flat, graphic, warm. Close, tactile, unhurried. If you can't get past one adjective, you probably want a conversation with the illustrator before a brief — which is a perfectly good thing to ask for.
Pick the view that answers the question
Different views answer different questions, and choosing badly is the most common reason a commission comes back unusable.
- Plan or overhead. Where things sit, how far apart they are, who is next to whom. Good for arrangements, useless for feeling.
- Sequence. How one state becomes another. This is what a transition needs, which is why the tile example asks for three stages rather than one beautiful frame.
- Cutaway. What's inside, behind or underneath. The view to reach for when the viewer has to understand a mechanism rather than a moment.
- Perspective at eye level. What it feels like to be in the space. Usually the last view you need, not the first, because it presumes the space is already understood.
One view, one question. If a single drawing has to answer two, you'll get a competent average of both and no clear answer to either. In the tile brief, View B doesn't repeat View A — it tests something View A can't show, which is whether the material reads as wrapping a room rather than papering one wall.
Set the rough checkpoint where it can still change
Ask for the rough once composition is decided and before finish begins, and ask for it in exactly those terms. Then say what it's for. A rough in this brief means flat values — two greys, pattern indicated rather than drawn — because you're reviewing whether the transition is legible, not whether it's attractive.
The reason to be that explicit is that "rough" is a word people fill in with their own expectations. Under deadline pressure, with several people watching, what tends to arrive is something small and finished, because a finished thing survives a review meeting and a rough one gets questioned. You get what the process rewards.
So separate the two notes before the work arrives.
The review note is about the question: in stage two, can you tell which surface the pattern is on, and does the tile stay the same tile as it crosses the corner? Does the pattern read as continuing around the edge rather than restarting on the wall? Is the tile at true scale in at least one frame?
The finish note is about everything else: matte glaze, joint depth, morning light, no glossy reflection on the wall. It waits. If you ask about light before you've settled geometry, you'll get a beautifully lit picture of the wrong room.
Here's the comparison that makes the point. Suppose you commission only one image, fully rendered, and the transition is conveyed by a soft glow spreading out from the tile. It could be lovely. It would also let everyone in the room feel that the problem is handled while leaving the actual question — how the pattern gets from horizontal to vertical — untouched. Now put that beside three flat grey panels with a scribbled arc pattern and a note saying where the camera stands. The grey panels are worse-looking and far more useful, because you can disagree with them. Disagreement is what you're buying at this stage.
Name the deliverable, the decider and the intended use
Countable terms first. How many views, how many stages in the sequence, how many rounds of rough review, and what "finished" means here — one key frame, a three-panel sequence, line art that sits inside a diagram. The tile brief asks for two views and three stages, so it should also say what a fourth stage would cost in time, since it isn't included.
Then the decider. One person, named, with authority to approve the rough. A committee reviewing a rough is how a rough becomes a meeting, and then a second rough, and then a missed date.
Then intended use. Treatment deck, internal review, client presentation, or material you might want to reuse later. Say which at the brief stage. An image commissioned for an internal document that later appears on a website is a different conversation and usually a different agreement, and it is much easier to have that conversation now than after the image exists.
Credit and a new-view policy belong in the same paragraph. If you intend to show the illustrator's name, say so. And write down that an additional view is additional work. Otherwise "could you just add the ceiling?" arrives as a minor finish note and quietly doubles the commission.
Actual rates, ownership and reuse terms are outside this article and are case-specific. The Association of Illustrators publishes a Guide to Commissioning at theaoi.com, which is the professional-practice baseline many illustrators will recognise; the last time that page was checked, on 18 September 2026, the request returned an internal error, so nothing here is drawn from it. Read it before you agree anything.
What the illustration doesn't prove
A drawing of a transition is a proposal about meaning, not a test of feasibility. The tile sequence shows that an audience could follow the change. It does not show that the change can be shot practically, that a set can be built, or that any of it fits a budget. Those are separate assessments with separate owners, and confusing them is how a treatment acquires a promise it can't keep.
So label it, in the treatment and in the caption: this is proposed, these are supplied product facts, this needs production assessment. "Illustration: proposed transition. Production route not assessed." Four extra words save a great deal of later embarrassment.
Two housekeeping habits are worth keeping. Store the approved rough alongside the finished image, because the rough is the record of what everyone actually agreed to. And if the question changes, re-brief rather than layering corrections onto the same artwork. Amendments stapled onto a finished image produce something that argues two things at once, which is roughly the definition of a picture nobody can use.
The review question
The brief should end with a question that can be answered before finish begins, in one sentence, by the person who has authority to answer it.
For the tile spot: in stage two, can you tell which surface the pattern is on, and does it stay the same tile as it crosses the corner? For the wide view: does the room read as the same material as the table?
If both answers are yes, go to finish and talk about glaze. If either is no, the fix is the view, not the colour — and you will have found that out at the cheapest possible moment, which is the whole point of commissioning the rough.
An illustration is ready to enter a treatment when its central question can be answered, not when it looks expensive. Those two conditions are unrelated, and only one of them is on your schedule.
Frequently asked questions
How do I know whether I need an original illustration or just more research?
Finish the sentence: We can't show how ___. If nothing fills it, you don't have an illustration problem yet; send the idea back or look for reference. If the missing thing is a fact, such as what the inside of a working biscuit factory actually looks like, that's research, not illustration. Original artwork doesn't establish what exists; it establishes what you mean.
What belongs in the fixed list and what belongs in the open list of an illustration brief?
Fixed facts are the ones you can't be wrong about: in the tile example, hexagonal tile, matte glaze, three colours, a 600mm repeat, visible joints, and at least one true-scale view. Taste, such as it should feel expansive, is open. Say why a fixed thing is fixed, because the reason tells your collaborator whether the constraint is load-bearing. The open list should be generous; the illustrator's job is to propose how the change happens. If you already know exactly how it should look, you need a renderer, and you should say so.
Why is in the style of a named living artist a poor brief?
It puts your collaborator in an impossible position, asking them to reproduce a recognizable body of work they didn't make. It also isn't a brief: it guesses at somebody else's problem-solving and doesn't tell the illustrator what property of that work you actually want. How much imitation you could lawfully use is a separate and less useful question. Name the property instead, usually in three adjectives, such as flat, graphic, warm.
What should the rough checkpoint cover, and what should wait until later?
Ask for the rough once composition is decided and before finish begins, and state exactly what it's for. The review note is about the question: can you tell which surface the pattern is on, does the tile stay the same tile as it crosses the corner, does the pattern continue around the edge rather than restart, is the tile at true scale in at least one frame. The finish note waits: matte glaze, joint depth, morning light, no glossy reflection. Ask about light before geometry and you'll get a beautifully lit picture of the wrong room.
What does an illustration of a transition not prove, and how should it be labelled?
A drawing of a transition is a proposal about meaning, not a test of feasibility. The tile sequence shows an audience could follow the change; it does not show the change can be shot practically, that a set can be built, or that any of it fits a budget. Label it in the treatment and caption: proposed, supplied product facts, needs production assessment. Store the approved rough alongside the finished image, because the rough is the record of what everyone agreed to. If the question changes, re-brief rather than layering corrections onto the same artwork.
