What is Office Lens?
Office Lens is the new camera built into OneNote for iPad that lets you take pictures of whiteboards, or printed documents, then enhances your photo by cropping, sharpening and straightening it, so it looks almost like a scanned image. Lastly, your picture is added to your note, so you can retrieve it later.
To use Office Lens follow these steps:
Create a note or open an existing one, then tap on the note to bring up the keyboard.
Tap , choose a picture taking mode: WHITEBOARD, PHOTO, and DOCUMENT, and take your picture
Office Lens will automatically crop your picture, but you can change the cropped image by clicking and dragging the circles to change the crop.
When you’re finished tap and Office Lens will add the photo to your note.
Tip If you want to switch back to the built-in iOS Camera app, go to Settings > OneNote > Camera Setting, and turn off Use Office Lens.
