I don't have a solution for location, but for photos, it seems like it would be best to require no permission to present a standard control (i.e. UIImagePickerController), but with the API only actually providing any information when the control completes (photo is selected, or control is cancelled). The user selecting the photo is implicit permission. Permission would be necessary to actually query for media programmatically, which is the real issue. Currently, they are conflated. For location, I suppose that the "Google Maps is using your location" bar at the top could be expanded and always present when the location permission is enabled. Tapping it would revoke the permission until it is enabled again. This could get annoying though, some apps legitimately do depend on location all the time.
