What's the best way to add geotags to photos if I have a GPX file with my location track?
I don't have lightroom and I'm on a Mac.
It reads your DPX files and uses ExifTool under the hood to manipulate the EXIF data in your pics.
I highly recommend HoudahGeo. I am not associated with the product, just a happy user. This is a Mac app, and really does excel at geotagging photos. It allows easy bulk tagging, and includes some extremely useful features, such as adjusting time, time zones, and provides a map for more precise pinpointing locations.
