Im asking the same question for the same reason. If you decrease the shutter speed and increase the iso youll get tracers right? Id like to see that. That would make for an interesting video.
Here is a video I did last night with the P3 Pro. Its in 2 parts, so the beginning of this video was the ending of part 1 where I came in to switch batteries. Just scroll into the video slightly to after I take back off.
