There are a variety of ways. My GoPro was generally set to take a pic every 2 seconds. I would set up a shot, gram a series and then weed out the trash in post processing. With my micro 4/3 bodies I use a mix of 10 second timers and wireless remotes. 99.9% of the photos here on the site are all shot by me. Proof that I need more friend that shoot well.
