I want to take pictures with my camera at a specific height (and perfectly horizontal). My tripod has an adjustable center column, but it is the usual unlock-pull-lock kind and it's not very practical for fine adjustments.
I have seen video tripods with a crank on the central column, but those I've seen are flimsy, and if I can avoid getting a second tripod...
So I wonder if there are easily adjustable column extensions.
Alternatively, the central column of my tripod can also be set as a horizontal boom, so maybe I should look at a focusing rail (assuming I can mount the camera sideways)?
