0.85: Labels 'Lens ID' and 'software' do not work on many camera raw files

Postby squeezechart » Wed Apr 12, 2017 7:31 am

looking at XnViewMP 0.85 I am very happy to use 'make', 'model' and more labels
for my camera raw images, but a test on dozens of camera raw samples shows that
'Lens ID' works on no testfile and 'Software' label does not work on some
Olympus (.ofr), Sigma (.x3f), Pentax (.dng) and Panasonic (.rw2) models but not on Nikon D4 (.nef) and some Sony (.arw) models
(a55, a77, a99, a7mk2..).

'Software' also does not work on Olympus E-M5, Olympus EPM2, Olympus XZ-2, Samsung NX20, Samsung NX1000.
Could they be added too?
Canon lists its Software in the field 'firmware' - could that be used in label 'software' as well?

Both labels seem to work on JPEG.

Sony a7mk2 testfile can be found here: https://drive.google.com/file/d/0ByLIAF ... sp=sharing

MakerNotes is a mess. (Un)fortunately isn't XnView's fault. Let's see if Pierre can come up with something but I wouldn't hold my breath...

If Exiftool is not an option, maybe this would be an option:

exiv2 shows 'Lens ID' and 'software' for Sony a55 and 'software' for Sony a7mk2 - 'Lens ID' is shown as "manual", but 'LensModel' entry is correct.
It seems to also show bit depth of many many raw images (Exif.Image.BitsPerSample) including recent Canon, Olympus, Nikon, Sony (I haven't seen this in ExifTool).
I did not check if it reports correctly for the other formats as well.
I just thought it would maybe help XnView (also because its sources are in C++).

Canon:
The lens is recorded to Exif.CanonCs.LensType
(beware: some 3rd party lenses identify themselves as others)

It can be used the more general Exif.Photo.LensModel , but some lenses identify here just as a mere focal length (for example 24-70 mm).

Nikon:
The lens is recorded to Exif.NikonLd3.LensIDNumber

...I told you that MakerNotes is a mess... :)

All the above are reported by exiv2
