Electronic shutter - was it used ?

[PeteGB]

I shot some 3000 images at a recent Mountain Bike event with my relatively new R5. I used the opportunity to experiment with different camera setting and perhaps naively assumed that I'd be able to tell from the EXIF data whether or not I'd used the electronic shutter.

I'm not surprised that Lightroom won't tell me but I was sure that DPP would show it.

For the life of me I can't find it anywhere and I can't find anything about if it's possible using Google. Any attempt to frame the question brings back a lot of links about using electronic shutter.

Can anyone here advise me if it's possible to determine what shutter mode was used to take a picture and if so how ?

Many thanks

Pete

I checked M50 II and 0x0a15 is 0. M50 II only has electronic first curtain shutter. I checked M5 and 0x0a15 is 331451531.

It will be available in the next release of exiftool.

Hi John,

Great, thanks!  This is very definitive.

I'll add decoding for this to ExifTool 12.33 (to be released later today).

When testing this, I also found a sample with a value of 3, so there will be a few unknown shutter modes out there.

I saw the release just a few minutes ago and found your name there ^^

Btw, how do you check the difference between Exif tags in an easy way?

[johnrmoyer]

I use Linux and macOS. I use ksh as my login shell on both. (I have used ksh since 1987 and I am slow to change.) I do not know of an easy way to do this when running Windows. Before I retired and was required to run Windows by my employer, I compiled versions of diff and less that worked from a CMD command line or ran Linux in a virtual machine. Phil Harvey wrote his own mult-diff program for testing exiftool. It has been more than 20 years since I wrote anything in Perl and it is likely that I would not understand his tools. CMD does have a for loop and variables, but it seems awkward to me.

I hope this example helps (I expect that it would work in any POSIX standard shell).

for i in 4677 4678 4679 4680 4681 4682 4683
do
exiftool -v3 -U IMG_${i}.CR3 > $i.exif
done

diff 4677.exif 4678.exif | less
diff 4677.exif 4679.exif | less

Find all CR3 files with "Canon_FileInfo_0x0017 = 2". (Edited to fix typos)

find ~/photos -name "*.CR3" | xargs exiftool -v3 -U | egrep "Canon_FileInfo_0x0017 = 2"

Thanks! I am using Ubuntu and what you wrote is understandable.

Worked.
