How to copy the 90º rotation tag of a vertical shot?

[hurodal]

hi there,

This is my first post here. First of all, thanks to all of you that contributed to such a great tool, specially to Phil.

I want to ask a question. Recently I wanted to emulate direct in-camera JPEGs for a special panorama software that doesn't accept anything but JPEGs from camera. I sucessfully emulated the image and copied almost all metadata from an original JPEG, except one problem:

the original shots are vertical and, as you may know, they actually are landscape oriented but with a special tag to rotate them. I could not copy this tag using EXIFTool GUI in windows.

how can I achieve this?

Thanks in advance!

Hi Hugo,

I don't know how to do this via the GUI, but at the command line:

exiftool -tagsfromfile source.jpg -orientation destination.jpg

Hi Phil,

thank you for the clarifying. I actually did a mistake; I did the copy with EXIFCopier (http://exifcopier.110mb.com/, which seems to not work properly) and not EXIFtool GUI. I tried it now with EXIFTool and EXIFToolGUI and it worked! in the last one you only have to check the orientation tag and use the copy tags from all files from a folder to another, so you can process a big number of files without having to process one by one.

Now I'm gonna see if it works or not.

thanks very much!

Hi Phil,

is it possible to extract the previews from multiple files and to also pass the orientation exif?

I'm writing a node.js app to remotely review and select my raws, the following command is sucessfully generating the previews for all my RAW files but the generated jpgs don't have orientation EXIF info.

/drives/c/Users/iies0073/Dropbox/bins/_IMG/exiftool.exe -b -PreviewImage -w -PREVIEW.jpg /drives/c/Users/iies0073/Dropbox/_TODO/node.js/teste4/RAWSTESTE

this is the full exif from a generated jpg thumbnail:

You can copy the orientation like this:

exiftool -tagsfromfile SOURCE_FILE -orientation PREVIEW_FILE

Thank you for the help and for providing this wonderful tool that i have been using for a long time!

I'm currently extracting the previews for all the files in a folder at once, then i cycle through the previews one by one to copy the orientation info from the rawfile to the preview file and finally i'm able to auto rotate the images with mogrify:

    exiftool.exe -b -PreviewImage -w -PREVIEW.jpg RAWFILES/
    for i in...
      exiftool -tagsfromfile 'Fotojonic-018-N-aurele2-20181218.NEF' -orientation 'Fotojonic-018-N-aurele2-20181218-PREVIEW.jpg'
      mogrify.exe -auto-orient 'Fotojonic-018-N-aurele2-20181218-PREVIEW.jpg'
    done
 

I'll be runing this from a webapp that i'm developing to review my imported raw photos.

Do you think there is a better/faster way to do this with exiftool or should i stop to try to improve the process and run with it?

This command will copy the Orientation for all files in a folder:

exiftool -tagsfromfile %d/%-.8f.NEF -orientation -ext jpg DIR
