Another way to put it is that the cyclist occupies a given area of the frame for only say 1/20th of a second. The rest of the exposure (2.95 seconds) is filled by only the background. And since both the background and the cyclist are illuminated by the same light and nothing more, the background wins.
David that was very well stated. I did a 3 second exposure (not posted) but the cyclist was nowhere to be found (as Neuro suggests) it was as if I taken a photo with no one in it. Indeed "the background wins". Seems this whole project is hindering on a much brighter light source against a darker background to create such a trail or as Gryphon mentioned an injection of bikers for the whole 3 seconds or reverting to a panning scenario.
tt - when you reference strobe I believe you are suggesting using the multi flash feature? that's actually a cool idea with the flash light..never thought of that one.
The effect you've 'discovered' is the main reason I have 10-stop ND filters - shooting architecture. Interesting architecture is often found in urban settings with lots of foot traffic, or the architecture itself is a tourist attraction with lots of bystanders. The long exposures with a 10-stop ND effectively blur out/eliminate pedestrians, passing cars, etc.- yes indeed I bumped into this effect by accident and a great idea for different uses of the 10 stopper.
