Editing Change Orientation of NEF Files in EXIF Data

Use `exiftool` on the command line to edit EXIF data of NEF files to control their orientation.

<pre>
$ exiftool -orientation#=1 [myfile.NEF]
</pre>

{|
|+'''Orientation Values'''
|-
|1&nbsp;||Horizontal (normal)
|-
|2&nbsp;||Mirror horizontal
|-
|3&nbsp;||Rotate 180
|-
|4&nbsp;||Mirror vertical
|-
|5&nbsp;||Mirror horizontal and rotate 270 CW
|-
|6&nbsp;||Rotate 90 CW
|-
|7&nbsp;||Mirror horizontal and rotate 90 CW
|-
|8&nbsp;||Rotate 270 CW
|}
<p class="alert alert-warning">The orientation is relative to the files original orientation, so for example applying a 90 CW rotation 3 times will leave the file rotated 90 degrees, not 270 degrees.</p>

An alternate method:

<pre>
$ exiftool -orientation="Rotate 90 CW" myfile.NEF
</pre>

`orientation` values:

Rotate 90 CW<br />
Rotate 180 CW<br />
Rotate 270 CW

<p class="alert alert-warning">Note that [[Command Line Image Tools|`sips` can also be used]] to rotate images.</p>

<syntaxhighlight lang="zsh">
sips -r 90 path/to/file.jpg --out rotatedfile.jpg
</syntaxhighlight>
