My camera is a Fujifilm X-Pro1, it offers the opportunity to choose a different ratio than the 3: 2 native ratio. Like the Canon cameras , and others, the Fuji cameras do not consider this ratio to store the image in RAW format.
I could easily return on this choice in Lightroom and the use of part of the image outside of the crop chosen in camera.
Strangely, this is not possible on my last images even as other images of the same import permit.
The lock in the crop dialogue is unlocked.
I can change ratio but not get outside of the space selected in camera
