For Halloween, Instagram has introduced a new camera format called “Superzoom” and Halloween-inspired face filters and stickers.
Superzoom is an easy way to record a funny video with dramatic sound effects. When you open the camera, you’ll see “Superzoom” next to “Boomerang” under the record button.
Tap “Superzoom” and then tap record to automatically zoom in with suspenseful music. You’ll also see a set of Halloween face filters and stickers in the camera, available through November 1st.
You can also add Halloween stickers to your photos and videos as a final touch.
