Append film roll comment field to each frame in that roll #41

Is your feature request related to a problem? Please describe. This applies to roll film and is mainly related to keeping film processing details together with each frame in the roll as Exif comment data. E.g. if a roll is developed in Rodinal for 15 minutes with agitation each minute, it is good to append this information to each roll as Exif data. Right now there is no easy ways to do this. This means that the processing data remain with the roll and not with each frame, where I believe it belongs.

Describe the solution you'd like An easy solution would be to have an option or a menu selection that allows me to append the comment field of the film roll to each frame in that roll upon exporting the data. In this way I can write my development process as a comment to the film roll, and then have that information copied to each roll's Exif comment field.

Describe alternatives you've considered Other alternatives include introducing new fields for analog film processing. But I am not sure if that is a good or needed solution because most image application will not be able to process them. An Exif comment filed is however recognized and shown in most image apps.

Additional context It is important that the roll comment field is appended, maybe after some marker like dashes and new line. In this way I can still add the frame comment as I do now, but then at the end, when I export the roll data, each roll is appended with roll comment.

You can take a look at the open source Windows app AnalogExif that does some of this stuff and uses Exif comment field to store all analog data about rolls and frames.

This might be an ideal use for the IPTC fields including "Digital Source Type" which contains an ID negativeFilm to describe the film capture in metadata.

This might be a solution yes. I think for me it depends on whether it can be used in Lightroom, which is the software I use. If ID 'negativeFilm' is ignored by Lightroom then I am back in square 1. The idea of appending it to the frame comment field is to avoid more specialized solutions.
