exiftool can show % DR set by Auto

[CAcreeks]

By the way, my preferred exiftool does not show the actual % value set by Auto DR., although Finepix Viewer does. Darn, I was hoping to delete Finepix Viewer.

Good news! With -u option, exiftool shows unknown tags, including "Fuji Film 0x140b" showing DR % set by Auto DR.

Nobody cares. Except my PC, which can be free of Finepix Viewer.

Thanks, this could be useful if I could get it to work, just have to revise my DOS knowledge, how are you using it, as a command line utility?

Hope it works with the F100, even Finepixviewer won't display DR properly.

I will give it a try. And I will wait for your reply to BrianJ RE: DOS.

Kind regards, Gary N W SFO

I have been using exiftool on Linux, being a long-time user of ImageMagick and GIMP.

However I just downloaded the Windows version exiftool-8.20.zip from Phil Harvey's website, extracted exiftool(-k).exe from the ZIP file onto my Desktop, and renamed it adding -u:

exiftool(-k -u).exe

Now I can drag & drop any JPEG file onto that desktop icon, and a command window appears with all its EXIF tags. Double-click the command window's title bar to maximize to full screen height.

I've managed to get this thing going by running it from a DOS prompt window in the default directory where the image files reside:

exiftool .jpg -k -U

The output for DR from the F100 looks like this:

Dynamic Range Standard
Dynamic Range Setting AUTO (100-400%)
Fuji Film 0x1408 0:100
Fuji Film 0x1409 0:100
Fuji Film 0x140a 0
Fuji Film 0x1422 2 2 0

This doesn't make much sense to me or tell me much for the following reason:

I was using a setting of ISO200 and DR=AUTO which limits DR to only 100% or 200% and I want to know which one it used. It just tells me that it was AUTO, and the values against 0x1408 and 9 are always 0:100 for all the files I have seen. If this is where the DR value should be then I should see 0x200 sometimes, I will keep checking.

That a file that has DR set manually has the following difference:

Dynamic Range Setting MANUAL
Development Dynamic Range 200

So I still cannot determine the DR of images taken in DR=AUTO

The output for DR from the F100 looks like this:

Dynamic Range Standard
Dynamic Range Setting AUTO (100-400%)
Fuji Film 0x1408 0:100
Fuji Film 0x1409 0:100
Fuji Film 0x140a 0
Fuji Film 0x1422 2 2 0

Oh rats, 0x140b is where the F200EXR puts its actual DR % setting, and your F100 doesn't write that field. The F200EXR has all the other fields you show above, with the same settings except that 0x140a = 3 (usually).

 

[CAcreeks]

With Auto DR, these fields appear:

Dynamic Range : Standard
Dynamic Range Setting : Auto (100-400%)
Fuji Film 0x140b : 400

With DR set to 400%, these fields appear:

Dynamic Range : Standard
Dynamic Range Setting : RAW
Development Dynamic Range : 400

I think you have clarified this for me, it doesn't matter what tool I use because the F100 did not write the DR data in AUTO. Pity, how about a FW update fuji.

Using exiftool with the F70EXR:

If the 140b field indicates hardware DR expansion, then how can I see this?:

EXR Auto : Auto
EXR Mode : SN (Signal to Noise priority)
Fuji Film 0x1303 : 0
Dynamic Range : Standard
Dynamic Range Setting : Auto (100-400%)
Fuji Film 0x1408 : 0100
Fuji Film 0x1409 : 0100
Fuji Film 0x140a : 3
Fuji Film 0x140b : 400
Fuji Film 0x1422 : 2 1 0
Fuji Film 0x1425 : 0
Fuji Film 0x4008 : 0

Many other questions:

Why does Dynamic Range: Standard always appear? Does this field have meaning with other cameras? Why didn't Fuji use it?

What is Development Dynamic Range? It tends to appear when shooting in P mode with DR400, but the 140b doesn't appear with it.

What does the 140a field mean? I see 0 or 3 in this field, but sometimes 3 appears with 100 in the 140b field rather than 400 as shown here.

Possibly it appears when using Software dynamic range, as on Fuji digital cameras that have the DR feature without EXR hardware. (Just a theory.)

I'm away from my photo database, but I think the DDR appears when you have set a specific dynamic range. It is as if the hardware provides a RAW capture that is developed into the DR 200% or DR 400% result.

What does the 140a field mean? I see 0 or 3 in this field, but sometimes 3 appears with 100 in the 140b field rather than 400 as shown here.

No clue about 140a. You need to look at the 140b field only when using Auto DR, because otherwise the DR setting appears in the DDR field, I believe.

As they say in Science when trying to get a grant, "more experimentation is needed."

I downloaded the updated EXIF tool (8.23) yesterday and found that it still doesn't report the actual DR that the camera chooses in DR=AUTO, at least for the F100fd. As suspected, this may be due to fuji not reporting it properly.

The other thing that is apparent is that when it says DR = AUTO (100%-400%), the label in brackets is just fixed data, because if you lock it to say ISO200, which means it can only use DR200% and DR400%, this label does not reflect that limitation. There are dozens of nuances like that.
