How to collect image datasets buyers can evaluate
Build a coverage plan, capture originals, document labels and prevent duplicate scenes from inflating an image dataset.

| Capture record | Originals, source groups and transformations |
| Label guide | Definitions, ambiguous cases and review status |
| Pilot package | Manifest, images and matching label files |
Collect against a defined visual task rather than a large file-count target. A useful image collection documents what was photographed, which conditions it covers, what was excluded and how each label was produced.
This is a planning workflow, not a claim that Fiund has commissioned your photographs. Agree scope and a pilot before spending money or arranging subject access.
Write a coverage matrix
List target categories and the conditions that matter: viewpoints, lighting, backgrounds, object variations and capture devices. Set project-specific quotas with the buyer rather than assuming balanced categories always fit the intended use.
Distinguish independent scenes from bursts, crops and repeated views of the same object. Keep a source-group ID so reviewers can inspect near-duplicates and correlated images.
Capture and preserve the originals
Check focus, motion blur, exposure and whether the relevant subject is visible. Retain native files and metadata that can be shared appropriately; record intentional transformations in derived versions. Do not upscale an image and present the result as native capture resolution.
If location or personal metadata is unnecessary or sensitive, plan an approved derivative export while preserving the controlled original. Photograph only within an agreed access and permission process; the intake form is not a place to upload private raw material.
Define labels before annotation
Write category definitions and examples of ambiguous cases. Agree whether boxes enclose the visible portion or estimated full extent, how occlusion is handled and whether masks include holes or fine boundaries. These choices need consistent project rules.
Keep label version, reviewer status and annotation method in the manifest. Model-generated suggestions should remain distinguishable from reviewed annotations. Export a small package and confirm the buyer can parse it before labeling at volume.
Review coverage and source groups
Inspect samples from every planned condition, not only the easiest photographs. Track rejection reasons and recapture needs. Keep related images grouped when planning evaluation splits so near-identical scenes do not silently appear on both sides of an evaluation.
Deliver file IDs, source groups, dimensions, categories, label paths and permission status. Check that every manifest entry resolves to a real file and that labels match the delivered image version. Ask for feedback on this pilot before scaling collection.
Frequently asked questions
Should I collect thousands of images before speaking to a buyer?
First confirm the intended categories, permissions and acceptance criteria. Existing images can be assessed without a speculative new shoot.
Can automated labels be included?
Yes as described deliverables, but identify their origin and review status. Do not claim human verification when it has not happened.
