The standard

Fidelity is binary, and the client sets the threshold.

Close is a category that only exists on your side of the conversation.

Everything else in a frame is judged on a sliding scale. The product is judged against a physical object the client has in their hand. There is no partial credit.

This changes how you work. On a normal shot you iterate towards good. On a product shot you iterate towards identical, and the review is a comparison rather than an assessment.

The practical consequence is that fidelity work needs its own process — a defined list of what must match, checked deliberately, rather than a general impression that the shot looks right.

02

Step one

Write the preservation list before you generate anything.

Per product, in specific physical terms, agreed with the client if possible.

For each product, list the attributes that must not change. Be concrete — 'looks right' is not a checkable item.

ex-014 Linen Overshirt
  - seven buttons, evenly spaced, matte horn
  - single chest pocket, left side, no flap
  - collar: soft, unstructured, no interfacing
  - seam colour matches body, not contrast
  - weave visible at this distance

This list does three jobs: it goes into the prompt as the constraint block, it becomes the review checklist, and it is the document you show the client when agreeing what fidelity means for this item.

Building it takes fifteen minutes per product and saves entire revision rounds.

03

Step two

The reference photograph is the product, not a description of it.

No prompt reconstructs a specific object. The still has to carry it.

Product work is image-to-image or image-to-video, without exception. The source is a real photograph, ideally the client's own, ideally unretouched and evenly lit.

Coverage decides what shots are possible. A frontal reference supports frontal and near-frontal shots. It does not support anything that reveals a side the reference never showed — the model will invent it, plausibly and incorrectly.

So plan the shot list against the references you have, or ask for the additional angles at the start of the job. Requesting three reference angles up front costs one email; discovering you need them at delivery costs a week.

Step three

Constrain the composition so the product does less work.

Every degree of movement is an opportunity for drift.

The reliable shapes, in order of safety:

  1. Product static, camera static. Nothing can drift. Use for hero frames.
  2. Product static, camera moving slowly. Geometry consistent, only perspective changes.
  3. Product moving minimally — a small fall, a slight settle. Budget several attempts.
  4. Product rotating or being handled. Expect to shoot this practically.

Choosing shape one or two for most of a campaign is not a limitation to apologise for. It produces a controlled, deliberate look, and it is what a real product shoot does anyway — the camera moves, the bottle does not.

05

Step four

Review as a comparison, at full size, cold.

Side by side with the reference, before you look at anything else.

Put the output and the reference next to each other at full resolution. Go through the preservation list item by item. Do not watch the clip, do not admire the light — check the list.

For video, check the final frame first. Drift accumulates, so the end is where it is visible, and it is invisible in motion.

Do this cold, ideally not immediately after generating. Having just produced something makes you a poor judge of whether it matches, because you know what it was supposed to be and your eye fills in the gap.

The item people skip

Count things. Buttons, stitches, panel divisions, ridges on a cap. Models change counts readily and it is the single most common failure that survives review, because nobody counts unless the list tells them to.

06

When to composite instead

The strongest fidelity technique is not to generate the product at all.

Generate the world; place the real photograph into it.

For the shots that matter most, generate the environment and the light, then composite the actual product photograph into the frame and grade the two together.

Fidelity becomes perfect by construction, because the product is a photograph of the product. What you are generating is the part that has no fidelity requirement.

It costs more setup and it is the professional answer for a hero frame. Use generation end-to-end for volume and variation; use the composite for the shot that goes on the homepage.
