One of the great joys of photography is being able to relive not only what you saw, but also where you were when you took the shot. Photo Supreme makes this possible by supporting GPX files for geotagging. If you’ve ever traveled with a GPS logger or tracked your hikes on your phone, you already have the data you need to map your images to the exact locations they were taken. In this post, we'll look at what GPX files are, how to use them in Photo Supreme, and how the time offset feature can save you if your camera’s clock wasn't set correctly.

​​

What is a GPX File?

​​

GPX stands for GPS Exchange Format. It's a standard XML-based file type that stores location data:

• Latitude

• Longitude

• Elevation

• Timestamp
   

Many GPS devices, smartphone apps (like GPX Tracker, Strava, or Gaia GPS), and fitness trackers can export your recorded movement as a GPX file. Each “track point” in the file represents a moment in time and a place on Earth. 

 

When you import this data into Photo Supreme, the software matches your photos' timestamps with the GPX track points. The result: each image gets tagged with its shooting location.

​​

Using GPX Files in Photo Supreme

​​

Here's how you can geotag your photos in Photo Supreme with a GPX file:

​

1. Record a GPS track while shooting

   • Start your GPS logger or tracking app before you begin taking photos.

   • Make sure the device's clock is synced as closely as possible to your camera's clock.
      

2. Import your images into Photo Supreme

   • After your shoot, bring your photos into Photo Supreme as you normally would.
      

3. Load the GPX file

   • Go to the GEO Tag panel in Photo Supreme.

   • Select your photos.

   • Click the GPX Tracks button to import the GPX file, or multiple files.
      

4. Apply the geotags

   • Click the "GPX Point" button to automatically align the photos' timestamps with the GPX track points.

   • Each image will be assigned its GPS coordinates, which you can see and use in Photo Supreme’s GEO Tab Panel or metadata.

Fixing Camera Clock Issues with the Time Offset Option

​

We've all been there: you go on vacation, forget to set your camera's clock to the local time zone, and now your photos are off by several hours. Normally, this would make GPS matching fail because the timestamps don't line up.

​

Photo Supreme solves this problem with its time offset option:

​

• When applying a GPX file, you can specify an offset (positive or negative) to shift your photo timestamps.

• For example, if your camera was still set to New York time while you were shooting in Paris, you'd apply a +6 hour offset.

• This adjustment ensures that the GPS data syncs correctly, even if your camera clock wasn't perfect.

​

This feature is a lifesaver for travel photography, where crossing time zones can throw off your metadata.

​

Why Use GPX Geotagging in Photo Supreme?

​

• Memory recall: You'll always know where each photo was taken.

• Catalog organization: Search and filter your library by location.

• Sharing: Export geotagged images with embedded coordinates for online maps or trip reports.

• Accuracy: GPX data is far more precise than manually tagging locations afterward.

​

Final Thoughts

​

If you already use Photo Supreme for cataloging your images, adding GPX-based geotagging can take your workflow to the next level. It’s an elegant way to combine the “when” and “where” of your photography. And even if you forget to adjust your camera's clock before a trip, the time offset option ensures your images still sync up perfectly with your GPS logs.

​

Next time you head out with your camera, consider running a GPS tracker in your pocket. When you import your shots into Photo Supreme, you’ll be able to retrace your steps: photo by photo, place by place.
