THE QUICK ANSWER
Photograph the unit that production is required to repeat: the sealed approved sample named in the purchase order, or first production itself. Before the shoot, lock color and gloss on a physical reference, the finished dimensions with tolerances, the carton dieline revision and the artwork revision. Keep one sealed copy of everything you shot. If production already differs from the images, correct the listing text first, then reshoot only the affected angles.
Which physical unit are the photographs of?
Decide this before you book a photographer. An approval sample and a production unit are not automatically the same object. Do not assume the approval unit must be repeated unless the order says so. Ask how the approval unit was built: which tool, which color batch, and whether the box was a running carton or a hand-made mock-up. Then choose. There are two defensible answers. Shoot the sealed approved sample that the purchase order names as the standard production must match, or shoot first production and accept that the listing goes live later. Anything else is photographing an object nobody has agreed to reproduce. Record which one you chose in the same folder as the images, so the next person can tell what the pictures are evidence of.
What to write into the purchase order
Put the match obligation in the purchase order, not in the email thread. Wording you can paste: production shall match the sealed approved sample named in this order, at the stated specification revision, and any deviation requires written approval before shipment. Use whatever sample identifier the seller actually issues rather than inventing one, and make sure the same identifier appears on the sample tag, in the order and in your image log. Ask for the sample to be sealed, dated and marked with the specification revision. Ask in writing who retains a copy and for how long. Catidog lists the approved sample alongside inspection criteria, change control, batch identification and the shipment-release record; the retention arrangement for your order is confirmed in the written quotation.
When does the shoot date actually get fixed?
The shoot date is fixed by the date the specification is locked, not by the date you book the studio. The published sample timings start at confirmation: a typical stock-item custom sample can be prepared within 7 days after artwork and details are confirmed, and a fully custom sample within 15 days after specification confirmation. Product, color, size, tooling and packaging can change these ranges. Every unresolved question about color, size or artwork moves that start date, and the shoot with it. If you chose to photograph first production instead, add transit to the plan: sea, air or express, matched to order size and deadline, and the unit still has to reach the photographer. Decide early which images can be provisional and which cannot. A size chart can publish from the specification. A hero image cannot publish from a unit that does not exist yet.
Approve color and gloss on an object, not on a screen
A hex value, a screenshot or a color number read off a monitor is not a color approval. Approve a physical reference, such as a signed lab dip for textile or a signed first-shot chip for a molded part, cut from the same material and the same thickness as the finished part, and state that thickness on the tag. Record gloss separately from hue, because they are approved separately and can move separately. Require new lots to be matched against the retained reference, not against the previous production run. Two things are deliberately absent here: a numeric color tolerance and a named viewing condition. Neither is published on this site, so ask for both in the written quotation. Which measurement method, which limit, and under which light the judgement is made. A quotation that answers all three is the answer you want.
What are the retouching rules?
Agree them before the shoot, in the same brief that names the unit. Three rules do most of the work. Retouching is limited to dust and sensor spots. No hue or saturation edits are made to the product itself. One unedited frame per angle is retained, shot with a neutral gray reference card in frame, and filed with the final images. Decide explicitly whether visible molding or seam marks may be removed, because if a retoucher removes a mark that appears on the delivered part, the image has stopped being evidence of the product. Treat finish the same way in the other direction. Do not approve gloss from a photograph. Approve it from the physical reference, then compare the photograph against that reference before the images are signed off.
The retail box is a second product with its own drawing
A box that changes depth is not a cosmetic problem. It changes the image, the dimensions stated in the listing, the shelf plan the retailer approved, and the freight. FedEx explains that dimensional weight accounts for package volume, and carriers may compare it with actual weight, so added depth on a light item can move freight cost. Specify the box the way you specify the product: internal and external dimensions with a tolerance, board grade, flute, print method and a dieline revision number. Make units per box a controlled field, so a change to pack count needs the same written approval as a change to the product. Then ask for one made-up box from the production run and measure it. A flat dieline proof says nothing about the depth of a glued, filled box.
Which changes trigger a reshoot, and who pays?
List the triggers in the quotation instead of arguing about them afterwards. The ones worth naming: color reference, material or masterbatch, hardware finish or plating, dieline revision, units per box, and logo or print method. If any of them moves, the photography may no longer show the product, so each needs written approval before production runs. Cost allocation is a separate question. Catidog publishes no standing reshoot-cost term; remedies are assessed against the agreed specification and documented evidence, and anything further is confirmed in the written quotation. Ask for it there, in writing, before the order: who carries the cost of new photography when a change originates at the factory, and when it originates with the brand. At reorder, before the second run ships, compare the retained approved sample with new production, and the listing fields with the current specification revision.
A useful comparison
| What you photograph | Fix in writing before the shoot | Evidence to retain | Reshoot trigger |
|---|---|---|---|
| Color and finish | Named physical color reference, material thickness, gloss level recorded separately | Signed chip or lab dip, plus the sealed unit that was shot | New masterbatch, dye lot or gloss level |
| Hardware and metal parts | Finish, plating and supplier part number | One loose component kept with the sealed sample | Component substitution or plating change |
| Product dimensions | Finished dimensions, tolerances and the measuring method | Measured record taken on the approved unit | Any dimension moving outside the stated tolerance |
| Retail box | Internal and external dimensions with tolerance, board grade, dieline revision | Flat dieline file plus a made-up box from the run | Dieline revision, board change or pack-count change |
| Printed artwork | File version, print method, placement and size | Approved proof printed on the actual substrate | New artwork revision or a change of print method |
| Pack count and weight | Units per box, net and gross weight, carton cube | Packed carton record from first production | Any change to units per box or carton dimensions |
| Cost of new photography | Who carries it, by origin of the change | The clause itself, in the written quotation | Not applicable — settle before the order |
