Sorry for the late reply. Always in mind, just a lack of time :-/

======================================
You will find geotagging examples here:

======================================

Technical Examples
==> Geotagging-Fotos: ZIP-Datei mit Beispielen (JPEG)
==> Geotagging-Fotos: ZIP-Datei mit Beispielen (NEF)
- Different Geotaggers on different Cameras
- With/without compass
- With/without indoor-buffer (some geotaggers mark GPS-EXIF from buffered data
with "impossible" values for satellite count. GPS needs 3 (4) satellites to get
a fix)
- On ZIP is JPEG one is Nikon NEF (Raw)

Outdoor-Examples
==> Geotagging-Testbilder für Programmierer (GPS/Kompass/Sonnenstand)
- Geotagging examples with compass in the field
- 360° shots from tower
- different places
-  zenith angle of sun shots (with, against, ... the sun)

Scenic Example
==> Sauschwaenzlebahn (Testbilder ZIP) 
A travel with a steam train and hiking back

---------------------
I think this could help you for now. The zenith angle of sun shots could be
interesting to build and test a “sun filter”. With coordinates + GPS time/date
it is possible to filter all pictures taken as dusk, dawn, … With compass data
added you can filter all pictures with frontal sun, sun from the back, sun from
the right, … In combination you can filter all frontal pictures of  sundowns, …
