Facebook is a social media site, where you chat with your family and friends. You might post a message to say "Merry Christmas" or to wish someone a happy birthday.
Yet, Facebook has really become a photo-sharing site, where everyone from presidential hopeful Donald Trump to companies like Macy's, to just about everyone else, is constantly posting pictures. In fact, more than 350 million photos are uploaded to the site every day.
So, it's no wonder Facebook is exploring new ways to let you express yourself. Earlier this month, we told you that Facebook is testing a Periscope-type live video, Facebook Live, where you can let people see what you're doing at the moment you're doing it.
Now, Facebook is slowly rolling out a new feature that'll let you post quick GIF-style videos. For now, it's only available to iPhone 6s users.
Which aren't just photographs. They are 15fps videos captured for 1.5 seconds before you take a 12MP photograph (or, 5MP with the front-facing camera), and 1.5 seconds after you take it.
The iPhone 6s and 6s Plus are actually recording before you click to take the photograph. When you click, it records the prior 1.5 seconds, takes the photo, and continues taking the video. The result is a little GIF. (See video.)
