Hasselblad X maker notes

[bokesan]

I'm aware that Hasselblad files suffer from multiple problems - that's why exiftool can't update .3FR files and .FFF needs -m. Even JPG files exported from Phocus are broken.
Still, a bit more metadata can't hurt, so I've tried to decode a few more fields. So far I've got just two useful finds:

[MakerUnknown] Unknown 0x004a : Shutter mode: 0 = leaf shutter, 1 = electronic shutter
[MakerUnknown] Unknown 0x005b : Drive mode: 0: single shot, 1: continuous, 2: self timer, 3: interval, 4: exposure bracketing: 5: focus bracketing

Less interesting, only in .fff files:
[MakerUnknown] Unknown 0x0028 : Phocus software version
This has differing formats on Mac and PC. My Windows PC has: "Phocus 3.6.2 64 bit PC", my Mac: "3.6.2 Mac"

Already in regular EXIF:
[MakerUnknown] Unknown 0x0015 : Camera Model

The only indicator of AF vs MF I found is in [MakerNotes] Unknown 0x004b, which starts with "AF_DEBUG_INFO: no valid AF debug info, maybe MF" in MF mode and "AF_DEBUG_INFO: focus point" in AF mode.

And that's all I got so far. Most of the info seems to be in binary blobs, or is not even present - Phocus itself also shows very little metadata.

I had hoped to find the lens leaf shutter count, for example, but no such luck. If anyone has tips or hints on how to find more, I'd be glad to hear them. So far I've used "-ee3 -U -G3:1 -api requestall=3 -api largefilesupport", sometimes with "-n" to extract metadata.

Regards,

Hi Chris,

Thanks for the info.  What model camera is this?  If I am going to add the ability to extract this information I will need a sample image.

Hello Phil,

the camera is the 907x. I assume that metadata from the X1D (II) will be mostly identical.

RAW from camera: https://www.chr-breitkopf.de/tmp/B0001294.3FR
RAW after import into Phocus (contains a few more fields): https://www.chr-breitkopf.de/tmp/B0001294.3FR

Info tab from Phocus (in German, sorry):

Thanks, but you posted the same link twice.

Oh, sorry. Just replace "3FR" by "fff"

More findings:

[ExifIFD] Metering Mode : Unknown (254)
Center-weighted (Hassy spelling: "Centre weighted") and Spot are correctly decoded. "Unknown (254)" is "Centre spot".

[MakerUnknown] Unknown 0x0005 : White-Balance setting:
  1 = auto, 10 = cloudy, 11 = shade, 2 = daylight, 3 = tungsten, 4 = fluorescent, 5 = flash,
  6 = manual (via manual entry or picker)

I see these did not make it into 12.41. Anything else I can do?

Sorry.  Adding support for a new maker notes will be a fair bit of work.  I've added this to my list of things-to-do, but I haven't had time to look into this yet.

It's not at all urgent. I wasn't aware there was no Hassy makernotes support at all yet, so I wrongly assumed it was just about adding a few tags.
