Take 1: Enhanced a raw file - saved 2x upscaled image of the moon and saw that output size was 172mb. realizing it was too large, I aborted the saving process and restarted.
Take 2: Enhanced same raw file but close cropped the subject first then saved 2x upscaled cropped image of the moon and saw that output size was unchanged - 172mb.
Steps to reproduce issue: Repeated the process.
