I’ve finally begun to learn in earnest photo stacking for astrophotography. The stacking software I use is quite picky about the input images and complains when all inputs are not exactly the same dimensions. I started checking on this and sure enough, my RAW photos are all 4608x3456. But, many of the TIFs in my exports from PhotoLab are 4610x3456.
Note: I am using version 1.2.3 build 82. Yes, I realize it’s old, but even so it should not be doing this. I’ve never noticed before because it was never so critical to my workflow before.
Here are my export settings. And suggestions beyond having to manually edit dozens of images by hand?
