Sure, I’ll send you something when I get home tonight. I can’t give any of my clients photos, but I can give you a photo out of the Pentax 645Z. I do photo stacking and several layers in Photoshop, background, piece of jewelry, reflections, shadows, retouches, painting, cloning, and I keep everything separated in layers, so these are sometimes 1.5 GB tiff files that are about 9000x6000 pixels and 16 bits. But lightroom does not read the layers but just the render of all those layers together. Here you can see how it behaves, and by the way, it behaves that bad even on a regular DNG straight from the camera. https://www.youtube.com/watch?v=m1VisL8dF3Y and here is 5.7.1 with the same https://www.youtube.com/watch?v=7EEFjurtwxE and here you can see what I do exactly https://www.facebook.com/victorw.photo http://www.victorwolanskyphoto.com/#!The-invisible-neck/c1ti3/33755DA7-7AAA-4573-B838-4D52E62D71C9
