I know of developers who would use this to eg rotate a logo to display down the side of a page (as this property affects layout). I don't see the harm in implementing this now On Safari 13.1 (and TP), the bottom image (canvas) is not upside-down, as EXIF orientation was taken into account Other browsers (and Safari before 13.1?) do not show this behaviour even if they support image-orientation: from-image These should be mapped onto standard EXIF Orientation: 1 - Horizontal (normal) 6 - Rotate 90 CW. 8 - Rotate 270 CW. Here is simple bash script (sure it can be sorter) which moves rotation form Camera to EXIF tag. It changes file only when original EXIF Orienation is normal and Camera Orientation is 90 or 270 (of course image data are not. The reason for that is quite trivial: whenever a photo is taken, the device saves the current accelerometer orientation into a corresponding Exif tag within the image metadata, so the viewer apps can retrieve it and rotate the photo accordingly. Problem is, this handy auto-correction feature is often not present in most softwares, libraries and.
