There's a few guidelines to help get a good photo and maintain the integrity of the game. Following these guidelines will help increase the chances of being able to use your submission.
1) Your submission must be a 360 photo. For most people that don't regularly take those or have 360 cameras, there are a few apps available that will let you take 360 photos from your phone (The app we use is called Teleport, but there may be better alternatives for different devices and systems). The library also does not have a 360 camera available to rent, so if more of us bring it up to them it increases the chances of them getting one.
2) We need an accurate indication of where it is, whether it's marked on a map (required for indoor locations), or exact GPS coordinates, we have to know where it is to make the game work.
3) The photo must be taken on BYU campus.
4) Outdoor shots, or indoor shots with prominent windows, should be shot in daylight and with decent weather when possible.
5) It may sometimes be unrealistic, but try to avoid photos with people in them as much as possible. If a particular person doesn't want to be in a photo, respect that.
6) Likewise, hide the picture taker as much as possible (avoid reflections, don't leave your stuff in a shot, etc)
7) Personal areas (eg inside a professor's office) should only be submitted with permission from the owner of that space. If someone with the authority to do so tells you that you can't photograph a space, respect that wish.
8) On campus housing follows a similar guideline, common areas are acceptable, but inside rooms will be rejected.
9) Don't submit photographs of gendered areas (eg a unisex/multipurpose restroom is acceptable, but a mens' locker room is not)
10) Avoid photos that include heavy construction or remodeling (unfortunately this takes out a huge chunk of campus).
11) Use common sense and be an honorable person :)
