ItermarkChoose milestones, not a quota
There is no correct number of photos. Add an entry before a major change, after a repair, at a decision point, and when the project is finished. A suggested cadence is only an example; the useful cadence is the one you can keep.
This is a text example, not a product screenshot or a real customer project.
Keep each entry legible
- Use a short label that says what changed, not only the date.
- Keep the same main view and add detail photos only when they explain a step.
- Use the previous entry as a ghost to line up the next frame.
- Leave the messy middle in the project; it is part of the evidence.
Compare the question you actually have
Maybe you want to compare the starting state with the finished state. Maybe you want to compare the surface before a repair with the first coat after it. A timeline is more useful when it lets you choose both points instead of hard-coding one before and one after.
