Choose what the text should do
A short scene caption, a detailed object description, and a search query are different supervision signals. Specify the intended relationship between image and text. Decide whether captions should cover the whole scene or a referenced region. Include examples that show the required detail and the facts that should be omitted because the image cannot support them.
Separate observation from outside knowledge
Product metadata may contain a verified identifier while a caption should describe visible evidence. Keep those fields distinct. Names, intentions, and events outside the frame should not appear as visual facts merely because a source description mentions them. Explain how uncertain or unreadable details are represented so fluent text does not disguise unsupported claims about the photograph.
Review diversity of descriptions
Repeated sentence templates can hide a narrow account of the collection. Review whether text captures the distinctions useful to the task, including spatial relationships and relevant attributes. Avoid asking for verbosity without purpose. A concise grounded caption can be more useful than a long speculative paragraph, particularly when several objects compete for attention within the same image.
Preserve authorship and revision history
Record whether text was source-supplied, human-written, machine-generated, or reviewed through a mixed process. Keep the exact image version attached because cropping may invalidate a description. Review samples for hallucinated objects and omitted key evidence. Sourcing availability and permitted uses for both the photographs and associated text should be established for the specific project before delivery commitments.
Review checklist
- Define the intended image-text relationship.
- Separate visible descriptions from external metadata.
- Review unsupported details and missing key evidence.
- Record text origin and exact image version.
