I have photos with EXIF data Long: 149.xxx, Lat: 35.xxx. I'm in Australia, so this latitude should actually be negative: -35.xxx. However, when I import these photos into QGIS using the "import geotaggged photos as points" tool, it places them correctly, in the Southern Hemisphere.
I have searched through the EXIF data in the Windows file properties dialog looking for a "Hemisphere: S" entry or anything to tell QGIS what's going on, and searched Google for a way that it might know, but I just can't find anything. What's the indicator that it should use Southern Hemisphere latitudes?
