No way! That is super cool! This is one of the things I love about digital photography. I know back in the day if you wanted a shot like that you had to just pray you got it right and you wouldn't find out until after they were all developed sometimes weeks later! Very nice shots! I included some light trails in my post today too!
Ohh yeah so true i started on film, I have an old film camera in a box xomewhere i always think about gettign some film and trying it again, but I guess I am happy with the ease of digital these days
