Office Lens allows you to take photos of whiteboards, automatically enhancing the text and formatting the image. To use this feature, open the Office Lens app and ensure it is set to "WHITEBOARD" mode. Take a photo of the whiteboard by pointing the camera at it and zooming in if needed. Once captured, the app will process the image to clarify the text and straighten it. You can then export the processed photo, along with a custom title, to various file formats and locations.
