Stop it!! You're confusing me!I think gopro always does the 180 degree rule and keeps the shutter speed double the frame rate and uses ISO for exposure comp. Now I will need to look into this. Haha. My only experience is with hero 3+ black so I'm not sure about hero 4.
Also slowing down shutter speed would allow more light in and exaggerate the effect I'd think. Ow. Brain. Hurts.
