Keep he creation date and add metadata authors

[Grummfy]

Hello,

I would like to modify an image (with mogrify or convert) but keeping the original creation date and adding the author information in the metadata of the picture.
It's only in the metadata , for the file modified or created I use touch for the date ....

Could you help me?

thanks

Imagemagick at this time has very minimal control of meta-data such as in EXIF profiles. It is basically not its job.

Your best solution is the one you found, use a program more suited to that task. ExifTool or Jhead, etc...
