Adjusting the orientation tag
Cameras without an integrated orientation sensor create images that need to be rotated manually. With JPG images, this could always easily be done with the lossless rotation feature of PIE.
The latest PIE v5.54 and PIE Studio v4.92 also support the rotation of RAW images by adjusting their orientation tag. This is done without creating XMP files.
Some modern cameras such as the Panasonic Lumix G-Series use the orientation sensor of the image stabilizer in the lens. With PIE, you can now get oriented RAW files (eg .RW2) even if you are using a lens without image stabilizer, such as the 20mm Pancake.
