Panorama software In the frequently encountered situation where the refractive index is the same in front of and behind the optical system, the nodal points coincide with the principal points. While that sounds a bit complicated, it's not in practice.

Your panoramic head needs to be calibrated precisely so that the camera and lens optical system rotates around the no-parallax (sometimes called nodal) point which virtually eliminates a parallax error from the image geometry and from the final panorama. Nothing seems to replace a good setting of the camera to make a panorama by stitching. For 5D Mark III L-bracket, the offset is 15.5mm, meaning I have to subtract 15.5mm from my vertical orientation measurement to get the landscape oriented one. Tripods and bases CanonRefurbished Everything considered, the best term for the no-parallax point may be (surprise!) To take pansorama photos, we need to rotate our camera. I am assuming here that you are using a panorama head on tripod and that the camera is levelled all these points are critical! If using a zoom lens for your panos, you'll need to determine the nodal points for all focal lengths you intend on using for your panos. We'll now see this in details. is the point on the lens about which it must be rotated in order to eliminate parallax when joining images to make a panorama. The principle is the same for mounting any other type lens on a camera when an adapter can be used. The quick method/trick to find the "nodal point" for panorama shooting is as .
