Used a Canon EOS 350D, 1 sec exposure, 100 ISO Speed on a night shot of a busy road I realize this is a visually repulsive image, just wondering what could have caused the dashed line?

m8 read through your camera manual or any book on camera techniques under "shutter speed",

You're a dumb cunt. That's way worse than just being a cunt.

The upper lights are smooth smears, right? Means the camera's exposure is okay. Ergo - moving lightsource must've been blinking. LEDs replace more traditional lightsources in car lighting. Unlike the rest they don't use up from turning them on and off constantly, so to save on power and other smart reasons I've forgotten yet which are a google away, they blink. Presto pronto, you can delete the thread now.

i got that they were caused by blinking lights, but how are there 3 separate lines? if it were caused by a bike, say, at most there would be two and unlikely to be that close together.

You were the one behind the camera, how can anyone other than you know? This isn't CSI:Clairvoyants, only an imageboard. LED car lights usually come in groups, maybe changing angle of passing car's somehow-shaped reflector uncovered more LEDs as it progressed? Why's this huge mystery worth an entire thread, OP?
>>2698326
maybe it was a newish car with LEDs on it? It's due to some sort of LED I reckon. they can give off a weird strobe effect sometimes, I bet a camera picks it up better than a human eye.
bicycle tail light?

The answer is obviously aliums.
LEDs blink cause they can't be dimmed, so they turn off rapidly, and our brains interpret that as being dim

Yes, blinking LED's.
This is extremely common, btw.
Most cars will give you light trails like that.
You will never be able to make classic looking light trails ever again.

Why would they dim taillights?
They blink becasue the AC rectifier doesn't supply them with a constant voltage.
LED lights at home also flicker, and it's really noticeable when you shoot at high shutter speeds, so something to watch out for.

>AC rectifier is directly connected to LEDs
sure mate
