When OpenEXR tags begin with a lower case letter, it looks like exiftool is changing them to upper case.  Is there some way to see exact tag names?  I attached a low-res sample.


PS D:\CF_Projects\hdr2\generated\exr> exiftool -X .\0000000.exr | findstr /I aspect
<OpenEXR:Aspect>1</OpenEXR:Aspect>
<OpenEXR:PixelAspectRatio>2</OpenEXR:PixelAspectRatio>

PS D:\CF_Projects\hdr2\generated\exr> exrheader .\0000000.exr | findstr /I aspect
Aspect (type float): 1
pixelAspectRatio (type float): 2

PS D:\CF_Projects\hdr2\generated\exr> exiftool -s .\0000000.exr | findstr /I aspect
Aspect                          : 1
PixelAspectRatio                : 2

PS D:\CF_Projects\hdr2\generated\exr> exiftool -ver
12.05

I do not believe so.  Exiftool has that listed as the tag ID, not the tag name.  See the OpenEXR tag page for the list of tag IDs and the names that exiftool gives them.  As you can see, in some cases, exiftool gives the tag ID a more human readable name, such as '_lay' -> Layout.

That's about all I can comment on.  Anything else will have to wait until Phil gets back from vacation later this week.
"It didn't work" isn't helpful. What was the exact command used and the output.

Ah, you can use the -v (verbose) option to get more data, but it would require more parsing from you.  For example, from the -v2 output on your file.
Maxfall = No data
  - Tag 'maxfall' (7 bytes, string)
  PixelAspectRatio = 2
  - Tag 'pixelAspectRatio' (4 bytes, float)
  ScreenWindowCenter = 0 0
  - Tag 'screenWindowCenter' (8 bytes, v2f)

You can use the new -G7 option to see the actual tag ID's (with "ID-" prepended).

> exiftool F004C001.exr -G7 | grep -i aspect
[ID-Aspect]     Aspect                          : 1
[ID-pixelAspectRatio] Pixel Aspect Ratio        : 2
