The official record credits two capabilities that happen to be the two halves of a product photo: editing only what you asked for, and holding a clean subject steady.
What GPT Image 2.5 changes
The launch page states the behaviour directly: “Images 2.5 is better at editing only what you’ve asked for, while keeping the rest of the details the same—even with more complex subjects and backgrounds.” For a catalogue that sentence matters more than any style claim, because a product photo is mostly a picture of everything you must not change — the label, the stitching, the colour of the cap.
The same page also credits the model with “more natural lighting and richer textures” and with preserving “the subjects in your reference photos”. Both point at one workflow: create the item once, cleanly, and treat every later image as an edit rather than a fresh picture.
Nothing official states how many images you may generate, what a finished image costs, or how accurate any particular detail will be: the launch page links to a pricing page instead of printing rates, and neither page publishes an accuracy figure.
Start from a white-background shot
Reserve one pass for the item alone. The goal is a frame where nothing competes with the product: flat light, no props, no styling, and enough empty space to re-compose later. A white field makes every later edit easier, because the model has less to preserve once you change the environment.
A single product photo of the item described below, shot straight on.
Plain pure white seamless background, soft even studio light from the
front, one gentle contact shadow directly under the item, no props, no
text, no hands. Fill about 60% of the frame height, centred, with clear
empty margins on all four sides.
Item: <describe material, colour, shape and every visible label>Two habits cut most of the rework. Describe the item by material, colour and shape rather than by brand name, because the model renders an approximation instead of loading your packaging artwork. And leave the margins wide — a tight frame looks better on screen and is much harder to re-compose afterwards.
If you want the item with no background at all, generate the transparent version in this first pass rather than cutting it out later; the technique and its limits are covered in the guide to transparent backgrounds.
Two examples: white frame and scene
The two passes are worth seeing side by side. Both start from the same item and differ only in how much of the frame the environment is allowed to own.
One: the clean catalogue frame
Reach for this when the platform wants the item on white, or when you need a master image to edit from later.
Using the image from the previous turn, keep the product exactly as it
is. Do not change its shape, colour, proportions, material or any text
on the packaging. Replace the background with pure white, remove the
contact shadow, and centre the product in the frame.Check the result at the size a listing actually shows, which is a thumbnail. If the item still reads at two hundred pixels wide, the master is usable.
Two: the styled scene
The scene pass is an edit, not a new generation. Name the surface, the light and the props, then state what must not move.
Using the same product image, keep the product identical in shape,
colour, proportions and labelling. Place it on a warm oak tabletop in a
bright room with soft daylight from the left. Add one small ceramic cup
and a folded linen cloth, blurred, in the background. Keep the product
in the same position and the same size within the frame.The failure to watch for is a product that quietly changes: a shade lighter, a millimetre narrower, a label that now reads slightly differently. That is what the “keep the product identical” clause is for, and it is why the master frame stays in the conversation.
Keep the product untouched
Every instruction that changes the environment should restate what stays. The model follows restrictions best when you pair them with a positive description of the part being preserved — “keep the labelling exactly as it is, and change only the surface it stands on” reads better than a bare “do not change the product”.
Reach for the narrower tool when the change is local. Selecting a region first, then describing the change, keeps the rest of the frame out of the edit; that workflow is set out in the guide to editing only what you select, and comment editing is the fastest way to mark several small fixes on one image.
One official caveat belongs here, because it decides how much you trust a single pass: “Highlights are not always precise, and edits may extend beyond the area you selected.” Check the boundary of a local edit, not only the middle of it.
A catalogue you can repeat
Once the master frame exists, a catalogue is a loop: copy the prompt, change the last line, keep everything above it identical. Surface, light direction and prop count stay fixed, and only the surface and the palette vary from item to item. That is what makes a grid of images look like one shoot.
Two habits pay off at this scale. Keep every prompt inside the conversation rather than in a notes file, so the edit history travels with the image. And edit one item at a time, because a change that quietly affects a whole batch is far harder to notice.
Ratios and formats
Marketplace rules differ between platforms and change over time, so treat them as a per-platform setting rather than a fixed number. What you control is the ratio you generate at and the format you export.
| Use | Ratio to generate at | Before publishing |
|---|---|---|
| Square listing thumbnail | Square | Check the item still reads at thumbnail size |
| Detail-page banner | Wide | Check the item is not cropped at the edges |
| Vertical story or post | Portrait | Check the item sits inside the safe area |
Generation happens at the ratio you ask for, and the ratio can be changed later without rebuilding the whole picture. The trade-offs are set out in sizes and ratios.
Check the image against the item
The risk in AI product photography is not that an image looks artificial; it is that the image disagrees with what ships. A scene that implies a different material, a fuller cut or a colour the item is not sold in creates returns, not sales.
Before publishing, compare the generated image with the physical item on four points: material and finish, colour under neutral light, every visible label and logo, and size relative to any prop you placed. Two further checks matter because the image is generated rather than photographed: whether the item’s proportions survived, and whether added text on a prop is legible enough to mislead. Generated images also carry C2PA metadata and an invisible watermark, covered in commercial use and watermarks.
Frequently asked questions
Can I skip the source photo?
Yes, and the two-pass structure still applies: generate the item on white first, check it against the real product, and only then build the scene. Generating straight into a styled scene is harder to correct, because there is no clean master to fall back on.
Why does the product drift?
Because a full regeneration rebuilds the frame instead of patching it. Ask for the change as an edit to the existing image, restate that shape, colour and labelling stay identical, and change one variable per attempt.
How many images can I make?
No official page publishes a quota, and none prints a per-image price, so treat both as unknown. The practical constraint is review time: every image still needs the same four-point comparison.
Is a disclosure required?
OpenAI’s pages do not state a commercial-use or disclosure rule for product photography, and this article does not invent one. Check your marketplace’s current policy and your local advertising rules.
A reusable two-pass workflow
Create the item once on white, with wide margins and flat light. Check that frame against the physical product before you build anything on top of it. Then treat every styled image as an edit: name the surface, the light and the props, restate that the product is unchanged, and review the boundary of the edit rather than only its centre. Keep the master frame in the conversation, so the next image in the catalogue starts from the same place.
