A watermark on a proof is a label, not a lock. It tells the recipient the image is a preview and attributes the work if the file is forwarded. It should not hide the face, product, or room the client is being asked to judge.
Decide what you are protecting
Most studio watermarks exist to discourage casual reuse of unedited frames. They do not replace delivery terms, license text, or access control. If the set is commercially sensitive, combine a moderate watermark with a private link rather than posting the PDF publicly.
Keep the mark consistent and readable
Use the same logo or short text across the job. Check it on both light and dark photographs; a white mark that disappears on a sky is not protection. Place it where it will survive a screenshot but leave expressions, labels, and product details clear. Filename captions must stay unobstructed or the client cannot reply usefully.
- Prefer a studio name or logo over a full copyright paragraph.
- Lower opacity until the image is still easy to compare.
- Avoid covering eyes, product labels, or property addresses.
- Apply the same settings to every frame in the sheet.
Apply it once to the whole sheet
Watermarking files individually is slow and produces uneven results. ContactSheetMaker can apply text or a logo across a contact sheet on Pro and Ultimate. Adjust size, position, and opacity, then scan a light interior and a dark detail before you export. The original watermarking announcement lists the controls.
Share the preview, not the master
Export the watermarked PDF or open a proofing link from the saved project. Send unmarked finals only after selects are confirmed. Wedding and listing jobs follow the same rule; see the wedding contact sheet guide for a client-facing example.
Open the contact sheet editor to test the grid first, then add the watermark when the page layout is settled.
