How to determine lens nodal point for panoramic photography

In response to requests from viewers of my panorama video "How to Create a Multi-row Pano", this video explains how to determine the nodal point(s) for your lens(es). http://lesterpickerphoto.com The equipment I use and shown in the video is as follows: Gitzo 3541 tripod, Really Right Stuff BH-55 ball head, Really Right Stuff leveling base (Item Code: TA-4-LB-HK), Really Right Stuff Multi-Row Pano Elements Package, LR. I now use Really Right Stuff tripods exclusively https://amzn.to/3onqs5R Really Right Stuff BH-55 Ball Head https://amzn.to/3a4gbGE
