SUMMARY
On the the Exif postprocessing tab, the ‘Light source’ drop-down lists many ‘Undefined’ light sources. These make no sense; the user can’t be expected to choose between several light sources which are labelled ‘Undefined’.

There are also two ‘Not Defined’ values for ‘Sensing method type’ under the ‘Misc’ tab.


STEPS TO REPRODUCE
1. Open/create an image.
2. Go to ‘Layer → Edit metadata → Exif → Postprocessing’
3. Click the ‘Light source’ dropdown.
4. Go to the ‘Misc’ tab.
5. Click the ‘Sensing method type’ dropdown.

OBSERVED RESULT
In the ‘Light source’ dropdown, five of the options are shown as ‘Undefined’ (along with one ‘Unknown’ and one ‘other’).
In the ‘Sensing method type’ dropdown, there are two ‘Not Defined’.

EXPECTED RESULT
There should be a maximum of one ‘Undefined’ light source option (perhaps zero – what’s the difference between ‘Undefined’ and ‘Unknown’?).

There should be only one ‘Not Defined’ sensing method type option (and for consistency, both dropdowns should preferably use the same terminology, i.e., both ‘Undefined’ or both ‘Not Defined’).
