Yet another effort to capture the ghost trails ... this time in inner ring road, Bengaluru:

Atleast this time I realized that, rather than using a very low 'f' value like f/32 to ensure better focus, it may be better to use something like f/6.3 and get clean red lines in a shorter time (about 10seconds). When the exposure was abt 2minutes, as I did last time, the trails get smudged and dirty. This time, with a lower exposure time, it was cleaner and clearer thick lines. Guess ... I need more experiments .. sigh!!!

I have had a pic before, trying to do the same. I guess, a stronger light (full headlight minus high beam), less bumpy road and a better camera/lens, had made the beam kinda straight. I used f/8 for this pic, about 12-13 seconds to expose the Versa staying still and a total of 18 seconds, including the motion capture. Earlier, I had tried f/6.3 and the beam looked a bit too strong.
