TIF file saved a JPG after orientation change.

[LCL999]

Using exiftool in Windows 10
This command seemed to work
/tt E:\5scans\fresh\A>exiftool -n -orientation=2 202012-M4P-00.tif
As I got
/code    1 image files updated
But the modified file was saved as jpg.
How do I change the orientation but still keep the file as TIF?

Exiftool only writes metadata.  It has absolutely nothing in it that can convert a tif to a jpg.  There is something else going on.

Maybe show what exiftool reports for the "TIFF". I know TIFFs that are actually JPEGs...

A tiff file can use jpeg compression, but it's still a tiff file.

Example output from exiftool on one created by Irfanview

Hi StarGeek
Thank you for your reply. I could not repeat the issue so you are right and I guess I had finger trouble initially.

On a related issue, after I used "orientation = 2", (i.e. mirror the image) there was no perceptible change in the thumbnails in the file listing (using Windows 10), nor did VuePrint (my preferred image display tool) show any change. Even though Exiftool showed all the "changed" files as "orientation = 2". However when I imported the images into LightRoom, sure enough the images had been mirrored.
I can live with that, now that I know. Any comment though?

See FAQ #6, specifically the second paragraph.

You set values for Orientation the same as they are output

• Horizontal (normal)
• Mirror horizontal
• Rotate 180
• Mirror vertical
• Mirror horizontal and rotate 270 CW
• Rotate 90 CW
• Mirror horizontal and rotate 90 CW
• Rotate 270 CW

To Orientation as a number, you need to bypass the printconv routine that displays the values in human readable form.  This is done with the -n (--printConv) option to affect all tags you set or with a trailing hashtag

Any of these would work, with the second line affecting all tags in the same command
-Orientation="Mirror horizontal"
-n -Orientation=2
-Orientation#=2
