Here's one I can't get my head around.
I have a raw file of a married couple holding some flowers.
In lightroom I cropped the image down to isolate the flowers.
I then exported the Raw as an 'Original' in Lightroom, so to another Raw.
Open the new exported raw in photoshop, the crop is there as I expected.
I renamed the raw to 'test 1' and imported it back into lightroom and the uncropped image appears and I don't want it to.
