Canon EOS R5 unsharp mask settings

[JohnMoyer]

Hello

Thanks for exiftool. Let me know if I can help.

It appears to me that the Canon unsharp mask settings when set in the custom style menu on EOS R5 for USER DEF 1 style are (maybe, just guessing, 129 indicates "Standard" picture style as the starting point):

Interesting, thanks.  So I'll decode these tags as the following:

Canon_Processing_0x000e --> UnsharpMaskFineness
Canon_Processing_0x000f --> UnsharpMaskThreshold

Can you find any setting that changes Canon_Processing_0x0010?

Also, Canon_Processing_0x0011 is not 129:  -1 is either 255 (1-byte) or 65535 (2-byte).  So I don't think this is the PictureStyle.

Thanks for correcting my arithmetic. I was never good at arithmetic and have forgotten much.

I have not yet found a setting that changes Canon_Processing_0x0011Canon_Processing_0x0011 but I will let you know if I do.

[JohnMoyer]

I loaded the "Clear" pf2 style file that I found in Canon DPP software application directory tree.

It appears to me that Canon_0x4011 contains information from the pf2 file.

The "Clarity" menu setting seems to be stored in Canon_CameraSettings_0x0033.

[Phil Harvey]

I don't know if I can do anything about 0x4011, but I can decode the CameraSettings_0x0033 if you tell me what values this takes for each of the Clarity menu settings.

Sorry.

The clarity setting ranges from -4 to +4 with zero as default. This setting is not available in all cameras.

FYI:

I get the same results with my Canon R6 as John in his first post.
I can also change the Clarity setting, and it appears in Canon_CameraSettings_0x0033.

So, feel free to enable decoding of these settings for the Canon R6 as well.

-Martin

[Phil Harvey]

Great, thanks.  I'll decode Clarity in the next release.  From my samples it looks valid for all R models, and for other models where the tag exists but isn't applicable it seems to have a value of 32767.
