Description Andrius 2020-05-13 21:28:10 UTC
Could this tool written in C++ be helpful for someone to write a plugin for digiKam to add camera info to scanned analog photographs in future?

To rickscheibner,

Are you the developer from AnalogExif tool ?

Anyway, AnalogExif sound a death project. Last commit to SVn come from 2010. All help messages from the forum still without response...

The tool sound popular, but unmaintained... I cannot found a fork in github for ex.

Maik, your viewpoint ?

Hmm, I'm a little hesitant. I've heard about it for the first time. Gilles, are you thinking of integrating AnalogExif as a plugin? On the other hand, we would then have to support the XMP AnalogExif namespace in digiKam. And then the question is whether the AnalogExif namespace is a standard that is supported by other programs. I do not think so.

Hi Maik,

yes, to port this AnalogExif tool as an external plugin.

I started to port the code as well to DPlugin + Qt5 :

I am not a developer at all. It was just suggested that I be available to answer any questions from an end user standpoint. Another application I've come across since doing my research is ExifTool which is a command line tool for accomplishing this same purpose. Of course, it needs a GUI for most users to be comfortable using it. It was last dated a week ago, on May 11, 2020. There's a GUI tool specifically for it, but I'm unsure how updated it is. I haven't personally used either one. 

https://exiftool.org/
https://exiftool.org/gui/

It has become popular over the last half decade or so to adapt older film camera lenses to newer mirrorless cameras. Since these were built in the pre-Exif days, they don't transmit any of that information to the image file that a modern lens does. I can see this being a valuable tool for serious photographers who wish to be able to accomplish this task. Additionally, the community of film photographers has been steadily growing in that same amount of time.  The ability to edit EXIF data, and apply it to several images at one time within digiKam, would be a helpful integration into that program. Currently, that task is not possible in digiKam. 

Thanks for taking a look at this. I'm available to answer any questions you might have.

Port to DPlugins as well done :

Maik, just take a look. It use a dedicated database to store devices information as cache or something like that...

Definitively, this tool, if we want to continue to work on it for a better integration, must be available as an external tool, not in digiKam core... I think...
