The handover is where this breaks
A photographer edits, an agent publishes, and the disclosure obligation sits with whoever publishes. That split is why most listing photos are altered without a word said about it: a study of roughly 40,000 listing images in early 2026 found 10.8% digitally altered, and more than 90% of those carried no disclosure at all. Not because anyone set out to mislead, but because a folder of JPEGs carries no record of what was changed.
You cannot disclose on the agent's behalf. What you can do is hand them a deliverable that makes disclosing trivial: the edit, the original it was made from, and the sentence to paste into the photo description.
What you actually send
Every paid listing comes back as an ordered set. Edited image at full resolution, exactly as the model produced it. The unaltered original, numbered so it sits immediately before or after the edit when a filesystem sorts them, which is what Canopy MLS §1.18.1 and SDMLS both require. A disclosure file per photo with wording for each surface the agent publishes to. And an audit record of what was done.
The reshoot you do not drive to
Sky replacement and day to dusk exist to stop a grey afternoon costing you a second trip. Both are alterations, both are disclosable, and both are cheaper than the drive. What neither should do is relight the building to match the new sky, which is the tell that gives a composite away, so the instruction holds the existing light on the structure and the render is rejected if the exposure stops reading as a photograph.
