I know you're thinking, "Cane, this is not a selfie." But it is. When I borrowed the personal submersible, I also borrowed a small underwater drone. Luna attached my phone to the drone and piloted it into position. Then, using my remote shutter, I took the selfie from inside the mini-sub.
Equipment like this might not be available to you. And honestly, it wasn't for me, but that is what makes this a challenge. Finding ways to use technology to take a selfie adds a layer of interest to your selfie story!
Always be careful not to hurt yourself or others. Be mindful of plants and don't step on them while preparing to take your selfie.
