1. Choose the frame before the project changes
Pick the view that tells the story: the whole dresser, the repaired car panel, or the room from its doorway. Include fixed edges that will remain visible. A frame that is easy to repeat beats a dramatic angle you can only find once.
2. Keep four things steady
- Position. Stand in the same place or mark a tripod position.
- Height. Keep the phone at the same height relative to the subject.
- Orientation. Keep portrait or landscape consistent within a project.
- Lens. Avoid switching between wide and zoom views unless you start a separate detail series.
3. Use the last shot as a guide
When the next entry is months or only a weekend away, memory is a poor alignment tool. A translucent previous photo lets you match corners, edges, and object placement before you take the shot. The goal is not to remove every natural change; it is to keep camera movement from competing with the project itself.
4. Keep the middle stages
Do not limit the series to the first and last frame. Add an entry after a meaningful stage: stripped, repaired, primed, planted, assembled, or painted. The middle is where the work becomes legible.
5. Compare any two dates
A final reveal is satisfying, but a timeline answers more useful questions: what changed between weekends, which step made the difference, and how long did the project actually take? Itermark keeps dated entries together so you can choose any two points and drag through the change.
There is no universally correct interval. Use a cadence your project can sustain, and keep the dates honest.
This is a text example, not a product screenshot or a real customer project. Add entries when the state changes enough to explain.
Start before the frame is right
Every step above describes a series that already exists. The commonest failure is not a badly framed series — it is a project that was never started, because the first photograph felt like it ought to be the good one, and the good one needed a tidier room, better light, or a free weekend.
Take it anyway. A project with one imperfect entry can be corrected at the next visit; a project with no entries has nothing to correct and no starting state to compare anything against. The frame can improve at entry two, and a note can say why it changed. The one thing that cannot be recovered later is the day the work began.
Keep the comparison honest
Changing light, moving subjects, and different lenses can still affect a comparison. The ghost is a reference that helps you match framing; it does not make different conditions identical. Choose any two dated entries when you want to inspect a change, then save or share the reveal for free.
