Thanks..if u release it after the burst then you will get overexposed fire in the middle of the burst..u have to release bulb exactly at the point of burst...
this will come with practice..always remember buddy capturing fireworks is one of the most difficult photography technique due to its unfriendly condition like extremely low light, smoke in front of you after couple of bursts in case there is no air to blow it away also u cant pump up the iso also sudden light with overexpose it & extremely fast moving subject..still its my fav technique
Hope this helps...
alright, thanks for sharing
shall try it out the next fireworks;p
