Exposure is critical for 3D scanning. Incorrect exposure will prevent the software from capturing the object's surface. CrealityScan offers two camera exposure control modes: Auto and Manual. When previewing or scanning, the exposure interface is shown on the right side of the software.

¶ Blue Laser Scanning
For Blue Laser Mode, we recommend users manually adjust the laser brightness and camera exposure time for better scanning quality. The desired state is to have both the markers and laser lines bright enough but not over-exposed. As shown in the image below, from left to right: underexposed, ideal exposure, overexposed.

¶ Adjust Exposure Manually
First, switch to Manual Adjustment mode.

Adjust the IR camera's exposure time so that the markers have sufficient brightness but are not overexposed. The areas marked in red in the IR image window indicate over-exposed regions.

Then, adjust the brightness of the laser line so that it has sufficient brightness but does not overexpose.

¶ NIR scanning
For relatively large targets, such as human face and body, Auto-Exposure can be used for scanning.
For smaller objects, Auto-Exposure may not be accurate. It is recommended to manually adjust the exposure time of the IR camera.
