The camera pushes in instead of changing focus
Change only the camera instruction to locked position and framing; remove reveal or move-closer wording.
Task template
Macro focus pull: change sharpness while the object stays still
Request one focus handoff between two visible depths while camera and object remain fixed. The original illustration is a conceptual macro input, not a tested H3 optical or lens-control result.
Includes original practice inputs and a review checklist. This prompt has not been independently tested with the generation model.
Download the input image below and upload it manually in the generator; the button carries the prompt.
01Prepare the inputs
- Use a still with two identifiable features at different depths. The supplied ceramic sample has a near circular rim and a farther raised collar.
- Start with the near rim sharper than the rear collar. If both features are equally crisp, deciding whether focus changed becomes less clear.
- Keep a stable crop with a visible tabletop edge or shadow. These references help detect a camera push or object slide masquerading as focus.
- Treat near and far focus as a visual instruction. Do not invent aperture, focus-distance or motor settings that the selected interface does not expose.
02Prompt and procedure
Copyable prompt
Use the uploaded macro composition. The ceramic sample rests completely still on the tabletop, and the camera position and framing stay locked. At first the near circular rim is sharp and the farther raised collar is soft. Shift focus slowly once from the near rim to the farther collar: the near edge gradually softens as the rear collar becomes clearer. Keep the sample outline, its two openings, surface ridges and contact shadow fixed throughout; blur changes clarity rather than reshaping the object. Finish holding focus on the rear collar. No camera push, no zoom, no object movement, no repeated focus hunting, no added detail.
Choose two readable depth targets
Identify the near rim and farther collar before running. Both must be visible; the prompt cannot focus on a hidden surface that the source never shows.
Lock geometry and framing
Name the object, camera and contact shadow as fixed. The intended change is relative sharpness, so do not combine the exercise with reveal, drift or push-in wording.
Compare edge clarity at the same locations
Take start, transition and end samples. Inspect the same rim edge and collar edge: near detail should soften as rear detail resolves, while the landmarks keep their positions and shapes.
Reject sharpening by invention
Check whether the final collar is clearer or newly redesigned. If ridges multiply or the opening moves, reduce the demanded focus contrast or choose a source with clearer rear structure before retrying.
03Check the result
- Object position and framing remain fixed across the shot.
- The near rim is the initially sharper target.
- The farther collar becomes the sharper ending target.
- The clarity handoff occurs once without repeated hunting.
- The same rim, collar and openings retain their shapes and relative positions.
- The tabletop contact shadow stays attached without a sliding object.
- The end holds rear focus without a zoom or newly invented surface ridges.
04Troubleshoot and finish
Both features remain equally sharp
Change only the focus contrast to near sharp/rear soft, then near soft/rear clearer; retain the same static frame.
The rear collar changes shape as it sharpens
Use a source with more readable rear structure while retaining the same focus path; sharpening cannot certify unseen detail.
Focus pulses back and forth
Change only the ending to one handoff followed by a hold on the rear collar; remove breathing or looping focus language.
End with the rear collar clearer and the original sample still in its starting pose. Save matched crops at both depth targets so a move or morph cannot be mistaken for focus.
