I was just wondering how the traffic police actually capture those speeding cars, especially at night.To capture fast objects without flash (those hidden cameras), we need a large aperture in order for a fast shutter speed to see the license plate clearly.
Large aperture especially if they are using a long focal length to capture you far far away will result in a super shallow DOF.
Also the headlights will also be glaring at the lens.. mm. so.. how did they do it?
Anyone tried any thing similar?
