In strong wind, the best fix is usually to reduce the wind’s effect rather than try to overpower it. Useful options are:

• Shield the camera from the wind with your body, a barrier, or windbreak.
• Use a sturdier tripod/head with plenty of capacity overhead; an under-specced ball head can twist even if the tripod legs are stable.
• Keep using added weight under the tripod, since that can help overall stability.
• Don’t hold the camera or lens by hand during the exposure—touching it often adds vibration. Use a remote release or self-timer instead.
• Try faster shutter speeds when possible to freeze vibration.
• If you need a long-exposure look, stack multiple shorter exposures rather than making one very long exposure.
• You can also test lens image stabilization on your setup. Tripod advice varies by lens, so results may differ.

In severe wind, some movement may be unavoidable, so combining wind shielding, a stronger head, and shorter exposures is usually the most effective approach.
