When images are photographed, digital cameras use orientation sensors to store an. I don’t know why Quicktime can’t do that Apple The following will report what the current rotation is set at in degrees: exiftool -rotation FileName. One way to rotate a photo losslessly (without decoding/reencoding) it to change the EXIF data that specifies the rotation (this data is set by the camera, depending on its orientation when the picture was talken). EXIF data is useful information about a JPEG image, hidden inside the file. It would be better to have not allowed tiff to be rotated rather than ONLY allowing jpg to be rotated. How fun Thankfully Phil Harvey has created ExifTool that allows editing of the metadata to rotate a video with no loss of video quality since it doesn’t need to be re-encoded. For example, to view the metadata of a JPEG file named example.jpg, you would type. exiftool followed by the name of the file you want to read, write, or manipulate.

(Oh yes I could install the Nikon software, but this creates sub-directories for their sidecar files etc.) To run exiftool on Linux, open a terminal and navigate to the directory where the exiftool file is located. When it comes to an image orientation there are two factors: how image is encoded and the EXIF orientation value.

And JPEG files are usually the only files where you face a wrong orientation - because the camera could not decide which orientation is correct. Some digital cameras can record the orientation of the camera when the photo is taken. This feature has been limited (and documented) to JPEG images a couple of versions ago.Ī user has reported that rotating a TIFF that way damaged the file and since I could not figure out how this could happen, I restricted this to JPEG files only.
