I set up a very cool little box, with a screwdriver poking out the top of the box, with a slit cut into a piece of cardboard that was placed behind the screwdriver. Using this setup I was very easily able to find the nodal points of my shorter lenses.

With my Canon 70-200, however, I found it next to impossible to figure it out at the long (135-200) end. Even looking through the viewfinder, as you move your head slightly (without moving the camera) you can see some parallax. I ended up just sort of "guessing" a value.

Any pointers for this lens? I have it mounted up using the tripod collar. ]]> Tips and Tricks Ryan0751 http://www.nodalninja.com/forum/showthread.php?5148-Canon-70-200-F2.8L-IS-II-and-Nodal-Ninja-M2-Nodal-point HDRI Handbook 2.0 - Alternate HDR Workflow? http://www.nodalninja.com/forum/showthread.php?5134-HDRI-Handbook-2.0-Alternate-HDR-Workflow&goto=newpost Fri, 31 May 2013 12:36:58 GMT In Christian Bloch's latest book, he outlines a Hybrid Stitching Workflow in sect. 6.4.9 using batched processing with Photomatix to a dual set of JPG and EXR files that one "swaps out" in PTGui.

Is anyone having success using this? - I am getting odd results I cannot explain. Yet, if I process the same Image Sets conventionally in PTGui - it works fine.

I'm attaching two sample images, I did not really work these to best ... just attempting "proof of concept".

If anyone would care to guess what I may be doing wrong ... I'd appreciate some feedback.
