I tried the trick for smooth panning today. It works as advertised! It’s amazing how a $0.05 item can add so much value and quality to your work! Explanation of the trick here and here. Right click to “save link as” this 2 MB .mp4 video where it shows how a panning looks like when using your hand to move the tripod fluid head’s handle, and how it looks when using the rubber band.
Conclusion: if you are shooting video and you do pans regularly, make sure you bought a tripod with a fluid head and you use that rubber band trick!
