I don't know how many of you would remember this. Geoff Coupe would remember. I had to look it up in the JLog archives. It was 2010. Microsoft did some weird thing with Windows Live Photo Gallery that completing screwed with GPS co-ordinates. I had thousands and thousands of affected photos.
I don't know what's happened since then because I uninstalled the program and then spent months repairing my photo metadata.
ANYWAY, one of the hangovers from this was strange time-stamps on my digital photos. I wrote a post about it in 2012 but I've been dragging my feet on doing anything because it's incredibly tedious work.
BUT, since it's New Year's again, I put it back on my calendar of things to do.
Just as an example, this is what one photo looks like in GeoSetter under Taken Date.
This is off by 2 years and a random number of months, days, hours and minutes. In other words, it's completely irrelevant. Under Created Date, I get what is likely the right date but the wrong time.
The place to look in GeoSetter for the best clues, and maybe the only clues, is Time under Image Info (ExifTool). There are enough time options to pick one that seems to be the right one. I feel encouraged it's actually possible to get through this.
For what it's worth, it's a simple matter to use this option in GeoSetter to change the numbers. And the Time Zone because that's likely wrong too.
