Nadir and Zenith Nodal test for the Nikon 10.5

Shot the smallest room to enhance nodal errors.By shooting the cylindrical with the centre column raised slightly, when it comes time to shoot the Zenith, loosen camera and rotate 90 degrees, drop the centre column down, loosen lower bar on the 302plus/303plus and slide to home position, shoot nadir and voila. Image straight from ptgui with much less parallax errors. Click photo for QTVR - needs post production- ptgui blend.
