image(file)-field templates and global fields

[sz-ligatur]

I just recognized that all my image-field-templates with custom fields (e.g. caption, location , …) get (re)populated with the field "title" as it is set as global. How do you handle that? Just keep the field and set it to not required and hide it in edit-screens feels a bit strange. I think keep title a global field is a good idea – how do you handle this in combination with the image-field-templates?

Thanks for any hints.
