thanks GullRaDriel
the shooting is in 2016
in that job I had
Sony a6300
Canon 5d iii
Canon 7d
Gopro hero 4
Tokina 11-16 - f 2.8
Nikkor 24 - f 2
Nikkor 50 - f 1.4
Nikkor 85 - f 1.4
Zeiss 135 - f 2.8
Hanimex 300 - f 4
Magic Lantern
I used all the cameras equally
I don't have a shutter speed rule
depending on the situation I expose more or less to have the effect I want
for example under the bridge (min 3.02 - 5d iii with tokina at 16mm), during the shots I increased the exposure times every 100 shots to get longer and longer line lights
if I remember correctly from 0.5sec up to 2 sec
