In order to accurately calculate damping times, we have been measuring the moment of inertia (MOI) for the various bits of a tripod setup.  In the last post we looked at the MOI of the tripod legs.  Here, I am going to be using the methodology described for measuring the MOI of a camera to […]

In the previous post, I demonstrated my methodology for testing the moment of inertia (MOI) for a tripod.  Initially, we were trying to make the assumption that the inertial mass of the tripod was irrelevant towards calculating the damping time of a vibration.  The data in this post suggests that this is not the case, […]

Our goal in measuring the moment of inertia (MOI) (also known as angular mass) of various camera systems and supports is to be able to make a reasonable calculation of damping time based on the stiffness and damping characteristics of the tripod in use.  In the previous post, we discussed the methodology for measuring the […]

In the previous post on calculating damping time, I showed that in order to complete our analysis, we needed to know what the moment of inertia for the cameras in question are.  The motions of a tripod are predominantly rotational, and so instead of just using the weight of the camera and lens, we need […]
