Correct the Date and Time of Photos using HoudahGeo 6.0

Correct the Date and Time of Photos using HoudahGeo 6.0

While the principles described in this blog post hold true, the actual Camera Setup interface has been reimagined for HoudahGeo 7.

When we refer to time we can say “It’s 2 PM”. This is easy enough to understand. It is early afternoon at our current location.

Digital cameras record date and time in a similar manner. When you load a photo onto your computer, you can see the time as recorded by the camera: 2 PM. The computer, however, cannot make much sense of this information. It is missing an important clue: location or time zone. For all it knows, “2 PM” could mean early afternoon in Hawaii or early afternoon in New York. A 6-hour difference!

What’s more, the camera clock may not actually have the correct time. You could have forgotten to set it as you traveled through time zones. Your photo of the New York night sky could indeed show a “2 PM” camera time.

Photo with incorrect time

We thus face two tasks:

  1. Set the correct time on the photo. E.g. “2 PM Hawaiian time”
  2. Make that time look “right”. E.g. “8 PM New York time”

Let’s walk through the process.

Adjust Photo Times to Match Local Time

Adjust Photo Times to Match Local Time

This summer, we travelled to Florida. I did not bother to adjust the clock on my camera to match local time. I left it set to my home time zone: Central European Summer Time (CEST).

When the time came to geotag photos from the trip, I just had to tell HoudahGeo that the camera clock was set to CEST. With this extra bit of information, HoudahGeo was able to figure out at what exact time each photo was taken. It then matched these times to GPS track logs to find where the photos were taken.

This photo of a Key Deer was indeed taken on Big Pine Key, Florida.

Key deer at 4 PM EDT. Or as the camera had it: 10 PM CEST
Key deer at 4 PM in Florida. Or as the camera had it: 10 PM European time.

According to my camera, the above photo was taken at 10 PM. This is at odds with what we see in the picture: broad daylight.
