When bringing in 2 photos or more to blend bracketed images of different exposure, when I use 'Auto-align layers', auto mode or any mode, I have tried all, stripped down to minimal changes, but when I scroll in I can see that they are not aligned perfectly. I click off and on the top layer whiled zoomed and I can see the difference between images. If I was just blending the clouds, that's ok. It's been like it for the last few updates. I am using CC.
