Pentax K-1 metadata

[Beholder3]

Hi,

1)
for the Pentax K-3II you already had decoded the AF Hold setting tag. Now on the K-1 that seems gone.

2)
Same with the sensor temperature tag

3)
AF Point Selected for the K-1 seems unknown

4)
Some other new settings like skin color or sharpness might be available somwhere

Can I help understanding those?

[Phil Harvey]

The AFPointSelected will be decoded for the K-1 in the next release.

Any other settings that you want to know, try doing -exiftool -a -u -G1 FILE and comparing the outputs to see if you can figure out where the information is stored.  For things stored in the binary data blocks it may be harder to figure out where they are.

Could it be that the K-1 sensor temperature is in

[Pentax]        Pentax 0x0244                   :
[Pentax]        Pentax 0x0245                   : .!@
[Pentax]        Pentax Unknown Info 0x0000      : 1
[Pentax]        Pentax Unknown Info 0x0001      : 0
[Pentax]        Pentax Unknown Info 0x0002      : 0
[Pentax]        Pentax Unknown Info 0x0003      : 0
[Pentax]        Pentax Unknown Info 0x0004      : 0

or the following?

In the K-3II it was coded closely following the pixelshift info data.

[Phil Harvey]

Thanks for the hint.  I'll take a look when I get a chance.

I fear even in v10.21 the Pentax K-1 "AF Point Selected" tag needs some work.

AF.S/Spot --> Fixed Center; 0
AF.S/Auto 33 --> Auto; 0
AF.S/Auto 9 --> Unknown (273); 0
AF.S/Select-1 (center chosen) --> Unknown (17); 0
AF.S/Select-1 (top row leftmost chosen) --> Upper left; 0
AF.S/Select-1 (lowest row, rightmost chosen) --> Unknown (33); 0

I suggest calling the individual AF points just with their number and a leading hash symbol, e.g.
AF.S/Select-1 (top row leftmost chosen) --> AF.S/Select-1 (#1)
because with so many points a text explanation is not better anymore.

AF.C/Spot --> Fixed Center;0
AF.C/Auto 33 --> Auto; 0
AF.C/Auto 9 --> Unknown (273); 0
AF.C/Select 1 (around center chosen) --> Unknown (17); 0      (first byte seems to give chosen point, second byte number of select)
AF.C/Select 9 (around center chosen) --> Unknown (17); 1
AF.C/Select 25 (around center chosen) --> Unknown (17); 3
AF.C/Select 33 (around center chosen) --> Unknown (17); 5

I do suggest a better naming scheme to correspond more to what the camera calls it.

AF.S/Select-1 (lowest row, rightmost chosen) --> Unknown (33); 0

I don't know what is going on here because version 10.21 should give "Bottom-right" for AFPointSelected (0x000e), and 17 should be "Center".

I suggest calling the individual AF points just with their number and a leading hash symbol, e.g.
AF.S/Select-1 (top row leftmost chosen) --> AF.S/Select-1 (#1)

Maybe you're right.  For Nikon we use a row-column designation, but with Pentax the grid isn't as rectangular.

AF.C/Spot --> Fixed Center;0
AF.C/Auto 33 --> Auto; 0
AF.C/Auto 9 --> Unknown (273); 0
AF.C/Select 1 (around center chosen) --> Unknown (17); 0      (first byte seems to give chosen point, second byte number of select)
AF.C/Select 9 (around center chosen) --> Unknown (17); 1
AF.C/Select 25 (around center chosen) --> Unknown (17); 3
AF.C/Select 33 (around center chosen) --> Unknown (17); 5

But the value of this tag doesn't differentiate between AF.C and AF.S.

I was more referring to "Auto;0" to be named Auto-33 and the Select ones explicitly named "Select-", where they currently are not named at all with trailing ",x".
Also I would drop the ";0" from the "fixed center" and maybe rename it to "spot" what the camera UI says.

[Phil Harvey]

Version 20.21 should not give "; 0".  It should be "; Single Point".  Are you sure you are running 10.21?

I checked it with the version 10.21 downloaded today from your website: windows version exiftool(-k).exe 7.222.352 Bytes 29.06.16 09:40.  nothing changed to 10.20

If there is a need, I can send you a picture

We have a problem.  Try running "exiftool -ver" to be sure the correct version of the library is being used.  (You could get the above output if running application version 10.21 with the 10.20 libraries, but the -ver option checks the library version too.)

And send me a sample if you want too (philharvey66 at gmail.com).

Ah.  Seems the Windows package wasn't updated properly.  I'll work on this.

- Phil

[Phil Harvey]

Sorry about that.  Somehow the most recent updates didn't make it into the Windows version of 10.21.

I've just released 10.22, which should fix this.

Seems to work now
