Code: Select all

 {EXIF:Shutter Speed} {EXIF:Aperture}
gives empty output when inserted to "Information displayed".

Reproducible with K52FAR2I00100.dng from this page and any of my own files too.

the field doesn't exist in EXIF metadata, it seems that exiftool recompute it

Is there a way of improving it? The information certainly is there, and other programs are reading it correctly.

I just tried in XnView MP 0.84 (good that the image and many others are still available for download):

The two fields

Code: Select all

 {EXIF:Shutter Speed} {EXIF:Aperture}
are still empty.

When using the fields

Code: Select all

{EXIF:Exposure Time} {EXIF:F-Number}
the value 1/400 and 8.0 are displayed. But these aren't the correct fields, right? (I'm not very familiar with EXIF data).

EXIF 2.3 specification (DC-008-2012_E.pdf) lists all four values.

Thank for mentioning it, I now have a workaround.

Thank you for trying out and reporting here, Alt Bass. If these values are part of the EXIF specification, XnView should also support them. So this bug section is the right place.

Shutter Speed/Aperture are not in EXIF fields
