I don't think it's my tripod because the lights from the building in the background are fine.
    Anyone can share some light as to what may be the reason?

    PS. Will post some of the pics later for reference.
    Bro, black card require getting used to and timing is crucial.. to capture multiple frames of fireworks.. cant really tell whats wrong with ur shots, some pics might shed some light, could be settings, angle of shoot or inappropriate use of black card...

    Did you switch off VR when shooting from tripod?

    I don't agree with raising profile. If you are good at it, its automatically recognized by people. I find that there are a few of you on CS are super duper good at certain niche of the area while some of them are all rounder which is good as it balance up everything like Yin Yang. Numnumball you are super good also lor. Should share share your knowledge leh..

    We can relax a bit. Don't have to think so much about when is the next outing to organize.

    I think it could be so, different apertures yield slightly different results. For example, a smaller aperture such as f16 will result in thinner fireworks trails, whereas a wider aperture towards f8 will cause the trails to "fatten" out and become more prominent.

    And is the buildings behind the fireworks sharp? Wonder is this go to do with ur tripod instability or whether is VR turned on like what Wildcat said..

    The buildings looks sharp (at least to me ) and the lens doesn't have VR.
    Here's 100% crop of the buildings.

    What about your friend's photos? Maybe can try some field tests... not sure. Google? Or swap lens and try this weekend.

    Maybe try to view RAW also. Not sure if jpeg renditions can cause such problems. Especially since it's zoomed in so much. From the big picture, cannot really see leh. Anti-aliasing stuffs... which I don't really know.

    Oh and one more thing... you know that pic #1 & #2?















    the buildings not straight
    Gotcha. Kekeke.

    It can be many things.

    One thing could be vibrations from people walking around/cars driving past/bass from music. All these things can introduce vibrations to your tripod. If your tripod is not able to damp enough of those vibrations, you will get minute shakes. These minute vibrations will not make too much of a difference to the buildings, since they are exposed for so long. But for streaks of light you will see them clearly.

    Another thing could be vibrations from wind, or wind blowing your strap, and or your strap is swinging around. When on a tripod, make sure you wind it up over something so that it does not swing freely. If you have an optech pro loop strap, remove the main straps.

    It could also be that your camera setup is too light. The more mass your ball head and your camera has, it actually improves stability. If your tripod comes with a hook, try to hook some weight below it. Hooking a freely swaying bag is not a good idea also. Best is if your bag is a heavy, and you use some bungee cords and hook to the tripod and the bag, but the bag is resting on the ground.

    Also for portrait orientation shots, do you have your camera swung to one side of the ball head? It may be causing some instability there. Try an L-plate. It is more stable. Since even in portrait orientation, the centre of gravity of your camera setup still stays in the center of the center column.

    Also check if your extended too much of your center column.

    I would rule out VR, small aperture diffraction here. Since you are shooting at F8 and your lens do not have VR.

    I think I covered all I can think of...

    Do you still have the raw files? Are you having any filter attached? What lens are you using? What are the equipment differences other than camera body?
