I've been asked what I use photospheres for. Here's one use case: marking trees to fell for the lumberjack.
I need trees felled at the back of our house. They're too thin, or dead, and I don't want them to fall on the roof at the next storm.
The lumberjack has a rather busy schedule, and normally he asks me to mark the trees, then he comes around when he has some free time to check the job and what he needs to bring exactly. Then he comes back with his tools and fells the trees. Typically, we're not home when he comes.
With the 360 camera, I can simply send him an annotated photo, he looks around in the comfort of his living room, and that's usually enough for him to size the job. So he only needs to come once to do the job and I get a discount.
Of course, I could also send him a bunch of flat photos and he could probably figure out where the trees are and what he needs to protect around them when he takes them down - particularly since he's been here before. But there's nothing like "being" in the picture to get a sense of what needs doing.
