An edit note is one change, not a new brief

A photo comes back and it is nearly right. The set is good, the light is good, and there is one thing: a price sticker nobody peeled off, a cap turned a few degrees away from the camera, a hand resting somewhere it should not be. For a long time the only honest answer to that was another take, and another take is a lottery you have already won once.

What the edit actually sends

An edit does not start from your brief. It starts from the picture you are looking at. That still goes back to the model as the reference, your note goes with it as the instruction, and your original uploaded photo rides along as a second reference, so that changing the pose cannot quietly redraw the label.

Most of what gets sent is not your note. It is a long clause asking for the same product — the same geometry, colours, materials, label placement and every character of text — the same person, the same outfit, setting, lighting, colour grade, camera angle and framing, and then: change only what the instruction asks for, and nothing else. The reason is written in the code beside it. An image model told to move a hand to a waist will happily re-pose, re-light and re-dress the whole frame unless it is told not to.

So the edit is weighted heavily towards keeping things. That is the property worth designing your note around.

Name a thing, not a mood

A note has to be something that hold-everything-else instruction can make an exception for. "Turn the cap to face the camera" is an exception: there is a cap, it has a facing, and nothing else is implicated. "Make it feel more premium" is not an exception to anything. It names no object, so there is nothing to change and everything to keep, and what comes back is the picture you already had, for a credit.

The test is whether you could point at it. If you can put a finger on something in the photo and say what should be different about that thing, it is an edit. If what you want is a different register — warmer, quieter, more expensive-looking — that was decided by the mood before the shoot, and no note reaches backwards into it.

One change at a time

A note can run to five hundred characters, which is room for four requests, and four requests in one note is the common way to waste one. Each clause competes with the keep-everything instruction and with the other three, and when the picture comes back with two of them done you cannot tell which clause failed.

Edits stack, so you do not have to crowd them. The result of an edit is an ordinary finished still and you can edit that in turn. Two notes with one change each cost the same as one note with two clauses, and they tell you after each one whether it worked.

The note also becomes the caption. The edit is filed in the set under "Edit:" and the first few dozen characters of what you wrote, so a note phrased as an instruction — "cap facing camera" — reads back as a useful label a week later. A note phrased as a complaint does not.

What it costs, and what it leaves alone

An edit costs one still, the same as a photo in the set, or two if you are rendering at 4K. If it fails, the credit comes back in full. It keeps the shape of the picture it came from, along with the pose and crop it was filed under, because it is the same picture changed rather than a new one. It is refused until the still it points at has finished rendering, so if the button will not take it, the photo is not done yet.

The original is never replaced. The edit arrives as another picture in the set it came from, and the photo you started with is still sitting beside it. That matters more than it sounds. It makes an edit a cheap thing to try, and it means a note that comes back wrong has cost you a credit rather than the shot.

What it is not

None of this makes an edit a general-purpose fix. An earlier post, "regenerate is a new take, not an edit", sorts a disappointing render into the things a fresh seed would change, the things the mood already fixed, and the things your reference photo already fixed. That sorting still holds, and an edit reaches none of those three groups. It reaches one nameable thing in one finished picture. It is the narrowest tool on the site, and the narrowness is why it works.

The short version

Point at one thing. Say what it should be instead. Keep it to that one thing, and write it the way you would want it labelled, because it becomes the label. If you cannot point at it, it is not an edit — it is the brief, and the brief is changed by shooting again.
