Bad format (39295)

[PaulMeesters]

Hi,

Since I am using a manual lens (LAOWA macro lens) on my SONY a7rIV at this time, I wanted to update my raw file's EXIF data with the Aperture and/or FNumber value I used to make the shot. However, exiftool can't rewrite the SR2Private entry.
I have no clue how to fix this, can anyone help with that ?

Hi Paul,

I get this with a sample I have here:

Code Select Expand

Are you sure you are working on an original ARW file?

Phil,

Yes, it's an original Sony A7RIV image, imported by Lightroom Classic from an SD-Card.
It's just a few images that give me problems, most are just fine and can be edited correctly.
It may be the LensTagger plugin (in lightroom) that messed things up. I tried that plugin first, but what that does is just call exiftool. LensTagger just reported that the action failed.


I will upload the offending .arw file to OneDrive and share it.

If you can download it and reproduce the error, you may be able to find out what's happening 

Thanks,
Paul

If the ExifTool command failed in LensTagger, then the file wouldn't have been changed.

It looks like all of the SR2 information is messed up in this sample.

The difference is in one of two places:

1. Lightroom modified the file when downloading.  This is possible, and dangerous.  The Nikon utilities do this, and they are well known for corrupting images.  And Adobe has a history of not caring about maker notes.

2. There is a difference in version 1.20 of the ILCE-7RM4 firmware.  My sample is from firmware 1.00.  Could you upload a file copied straight from the memory card (ie. don't use Lightroom)?  I'll take a look to see if this has the same problem.

Hi Phil,

The original file was still on the SD-Card and I uploaded it to one-drive:
https://1drv.ms/u/s!AqsA0RVIz7_DzHmy1XklO4zLWbDM?e=Jbav4F

I noticed there was a difference in filesize. 119.970 KB for the original, where the corrupted one is 119.884 KB.
Yes, I know the sizes are ridiculously enormous  but if you want the megapixels, you will need the space too

My knowledge of the raw-file make-up and sections is very little to none. I have no clue what SR2 info is, but I can imagine something concerning 'maker notes'

Best regards,
Paul

Hi Paul,

Wow.  OK.  Adobe is corrupting the file when downloaded using Lightroom.  The original file is fine.

Lesson learned.

Yes, the SR2 section is part of the make notes, and contains a LOT of information.

P.S. That's MB, not KB.

And there is MUCH more unknown SR2 information lost.  You can use the -u option to see it all, but the output is too long to post in the forum -- there are a total of 1844 tags lost.

eermmm, no Kb according to Windows:

Thanks Phil,

I will tag the raw files before importing them into Lightroom. Just copy them by hand from the SD card to a tmp folder, tag them, and import from the tmp folder.
Good thing we now know that lightroom corrupts the files on import

Paul

I noticed there was a difference in filesize. 119.970 KB for the original, where the corrupted one is 119.884 KB.

Your image shows 119,970/119,884 KB or 119.97/119.884MB (commas to separate the thousands).  If it was KB, it would just show up as 119KB



For some reason, my brain freezes up when trying to figure this out quite often and I make mistakes like this a lot.

[PaulMeesters]

extra confusing is the locale differences.
I'm from The Netherlands, and here the decimal separator is the comma, the thousands seperator is the dot (period). In the U.S.  that's the other way around 

anyway the files are around 117 MB (117 MB (122,849,280 bytes)    -- here I use the US separator
