Write FocalLengthIn35mmFormat with FocalLength * factor

[did77]

Hello

How to write the variable" FocalLengthIn35mmFormat " has to leave the variable" FocalLength " with a factor multiplier (for example 2 or 1.5)

I use the line of command "Exiftool direct" of the interface "ExifTollGUI"

I tried the formula below, but it does not work

-exif:FocalLengthIn35mmFormat<FocalLength*2

In advance thank you

Try this instead:
-exif:FocalLengthIn35mmFormat<${FocalLength#;$_*=2}

Since you want to process the value first, you need to use the advanced formatting.
