Updated* — If you take photos with any camera or device which includes an orientation sensor, and that includes most devices available today, then you really should be hard rotating your photos to their proper orientation. Here’s why —
Windows 10 will display photos which include an orientation tag (in the image metadata) in their proper orientation. What Windows 10 does not do is actually hard (i.e. “physically”) rotate the photos automatically (or indeed even manually while “rotating” via File Explorer or Photos). The photos only appear to be rotated! This scenario can, and does, lead to any number of issues when the photos are displayed outside of the Windows 10 environment. There may indeed be many instances when the photos do not display properly oriented.
AutoRotate reads the orientation tag and hard rotates photos automatically.
It is suggested that the photographer take a few moments and automatically hard rotate their photos after downloading them to their Windows computer (no matter the Windows version). Hard rotating your photos will permit them to be viewed properly oriented on any operating system, and in any viewing environment. Select an entire folder and AutoRotate.
During the hard rotation process:
- the JPEG image should be rotated using a lossless algorithm
- the orientation tag should be reset
- image dimension metadata tags should be updated
- the photo’s EXIF thumbnail should be regenerated to reflect the new orientation
- no metadata should be stripped or corrupted in the process
To do all these tasks properly is no easy feat. AutoRotate attempts to do these tasks automatically, and for the most part succeeds with photos from virtually all cameras. I have confidently relied on it for years to rotate the photos from my Canon cameras.
During the simple installation process, multiple shortcuts to AutoRotate are integrated into Windows to make access as simple as selecting “AutoRotate JPG” from Windows context or Send to menu. Please see the readme file during installation for additional ways to access AutoRotate.
Please note that some cameras, even some “professional” models, do not include an orientation sensor, and as such AutoRotate would be ineffectual. Please first test AutoRotate on a photo (copy) to determine its efficacy.
