[QUOTE="Gewitty, post: 556635, member: 41952"] As an experiment, I first tried zooming into the JPG version (using XnViewMP), which initially fitted the screen at 13% size. I can zoom right up to 100% and still retain detail. Then I tried exporting the file. First as a JPG (100%), which gave me a file of 5.9MB with an image size of 4000 x 6000 px. Exporting as a PNG gave me a file of 13.7MB, again with an image size of 4000 x 6000 px. And finally, exporting as a TIFF gave me a file of 72MB, with an image size of 4000 x 6000 px. The original RAW file is 24.1MB, with an image size of 4008 x 6008 px. Looking at some images taken as JPG's on the same camera shows a file size of 24MB, 6000 x 4000 px, which leaves me somewhat confused, since the RAW files should surely be larger than the JPG's?
