① Keep the object stationary throughout image capture. Ensure sufficient color contrast between the object and the background, and keep the surrounding environment clean and free of clutter.
② Natural lighting is recommended. Maintain a stable, uniform, and well-lit environment.
③ Capture images at a resolution of 2K or higher if possible. Disable portrait blur, beauty mode, and filters. If supported by your device, lock exposure, focus, and white balance before shooting. Do not tap the screen to refocus during capture.
④ Maintain an appropriate shooting distance and move slowly, smoothly, and at a constant speed. Keep the object centered in the frame and ensure it occupies at least half of the image width or height. It is also recommended to keep the device orientation consistent during capture, avoiding switches between landscape and portrait modes whenever possible.
⑤ To ensure sufficient viewpoint coverage, capture at least one full 360° pass around the top, middle, and bottom sections of the object. Adjacent images should have adequate overlap. It is recommended to capture at least 20 images at each height level (top/middle/bottom).
