I did the export chain 4 times and NO change in the image. The histogram from the first to last has just an very minor movement (almost imperceptable) probably due to jpg compression but the photos are visually identical when brought back into lightroom
And that histogram movement is to the left as mine?? The second image is darker than the first one. But that´s effectively imperceptible if you view the 2 images at the same time in your screen. If you use a viewer which let you swicht quickly from one image to the other then if what happens to me, also happens to you, will see the difference.
I have histogram movement just with 1 iteration of the process. Slight, but movement.
BTW, nothing of this happens if I do the same with PS6 or Capture NX2. Only LR 4.4 makes this change in my JPG´s.
Thanks!!
