Instagram has announced a new feature called Instagram Direct. Instagram Direct lets users send photos and video messages to friends. Instagram also announced in a blog post that they have hit 150 million users.
When opening Instagram, you will see a new icon at the top right corner of the home feed. Tapping on it will open your inbox where you will see photos and videos that have been sent to you.
To send photos or videos to specific users, tap the camera button and enter the photo or video capture and editing screens. At the top of the share screen, you will see an option to share with your followers or to send to people directly.
