Renamer Increase TAG value by a specific value

[ChristopherFoto]

Hello community,

I would like to rename files with the Renamer, for this the value of {File.MD.Nikon::Main\55\MechanicalShutterCount\0} should be increased by 540. So the value 4651 should become 5191.
2025-03-04_13-42-28_DSC_4615.NEF --> 2025-03-04_13-42-28_DSC_5191.NEF
Unfortunately, I haven't found anything in the documentation, or I've been looking in the wrong place.
Does anyone have an idea how I can implement this

I think, with the math-variables,

like

{File.MD.Nikon::Main\55\MechanicalShutterCount\0|math:add,540}

But please check the variables, if it is correct, and there search math. Nice possibilites.

Hello Markus,

you are my hero, thank you very much, that was what I was looking for.

Regards Christopher

I have troubled the search, have found, unfortunately, nothing, perhaps, I have looked for the wrong concept.

See math:Op, Value {,Decimals}

Cool, Christopher, that it helped you.
Personally, I find variables really very helpful. I do not more know, when Mario added the math-possibilites to the variables, hmm, maybe 4-5 years ago? Maybe longer, but "die Zeit fliegt manchmal nur so".

It's the usual thing. When you have never used something or not for a long time, it's hard to find what you are looking for.

I've thrown the problem at a local AI I'm running, feeding it the Variables help topic for RAG. This is what it produced:



My prompt was: IMatch can do math with variables. How to add 540 to the result of a variable?

I think AI will be a big help with questions like this. I already use AI regularly to do boring stuff.

Wow, very impressive.
That is really cool.

Yep, I agree, AI will be a lot of help. 

(last year the AI (even from Bild-hey  ) created for me a phyton-script with instructions, how to use, for Blender ... and it worked.
