--- title: Fine Tuning A Lens slug: scenario/fine-tuning-a-lens docTags: createdAt: 2024-10-03T09:20:05.342Z --- Lens finetuning is a process that allows a user to make changes to the calibration information of a lens. Finetuning is only possible for Template and manually imported lenses and is not required for VLP lenses. For lenses that may require fine tuning, a notification is displayed on the lens icon when they are created/imported. The lens **CAN **be used without fine tuning/refining but for optimal results it is recommended to conduct the fine tuning process. ::Image[]{src="https://api.archbee.com/api/optimize/Qn0sdcVrDcDbwMFmH0oYn/iP6z3_okPuUFypNSAFZcI_image.png" size="46" width="305" height="84" position="center" showCaption="false"} The finetuner can be accessed at any time be either clicking the yellow notification or by selecting the “**Refine Lens Calibration Points**” option from the hamburger menu ::Image[]{src="https://api.archbee.com/api/optimize/qD4GJYL5qMffFW6GWjgo7-XspDKZQspiOCROwamO-tq-20241029-182554.gif" size="64" width="800" height="712" position="center" showCaption="false"} The fine tuning steps overlap with the manual lens calibration steps, please see the manual calibration section for details on the elements specific to lens fine tuning
