Parsing Maker Notes

[blue-j]

Hey there,

This is an odd request for help I suppose!  What can I do here:

I need to look into any image, see if it has any maker notes and then parse the manufacturer name from the family name for it.  EG  makernotes:samsung:depthmapdata

I know all about the other namespaces that have this information, like EXIF; but I still need this precise solution.

I can parse the output outside of ExifTool, but I don't know how to efficiently extract one maker note from any image!

Yours in struggle,
J

I don't recall any way to list just the group names, so you would have to parse the output.  Something like this

Code Select Expand

C:\>exiftool -if "$MakerNotes:all" -g0:1 -a -s -makernotes:all 2022-04-02_09.51.45.Jpg | grep -E "^----"
---- MakerNotes:Nikon ----
---- MakerNotes:PreviewIFD ----
---- MakerNotes:NikonCustom ----

Thanks Star-man!  You got me headed in the absolutely correct direction. To parse the output further, there is this joyful regex:

Code Select Expand

(?<=---- MakerNotes:)(\w+(?:\s+\w+)*)(?=\s* ----)
And damn it, GPT-3 wrote it for me.  Wow.

You are awesome.

I just watched a video course on mineral evolution, and my mind was blown open.  I knew we are all made of stars, but this guy connects all the dots from the Big Bang through star lifecycles through heavier elements, the creation of Earth, and then of life.  Highly recommended, Mr StarGeek!
