Markup is a feature that allows you to use a pen tool to draw on a photo.
To Markup a photo, start by adding one to your Project or Project Files and open it in expanded view by tapping on the photo. Tap the pencil icon in the top right corner to begin editing your photo.
Next, tap the squiggly line to begin Markup.
Now, you can use your finger to draw on the photo! Dragging your finger along the color bar will change the color of the pen tool. If you make a mistake, you can tap the undo button (arrow pointing left).
When you're done, tap the check icon in the top right corner to send your new masterpiece to a FYI Chat, Project, or use a 3rd party app to share your work.
