He answered i just had a very old 16mm Arri BL from the Vienna film academy and they had the feeling that iam poor to because of this old camera.
So it was easy just to follow them and grab the right pictures without that they get disturbed or take a notice.
What iam thinking of if we go and film a documentary about the homeless we should dress like a homeless even the camera should be in a plastic bag like the homeless Carry them with.
That’s a very old rule for cameraman’s dress like your audience , if you are on a Vienna opera Ball you also have to dress like a Penguin even when its uncomfortable to work with that dress on a camera.
