Hello,
I took some wedding pictures at a single location over a evening, starting from 4 pm until 10 pm. Unfortunately, I forgot to turn on the GPS on my camera. I am planning to geotag all the pictures (about 200) using the CSV file format since I have the GPS coordinates of the location.
Will it be okay if the CSV file has just one row with GPS coordinates with GPSDateTime to match 4 pm or do I need to include multiple rows with different GPSDateTime, say an hour apart, going until say 11 pm? (I am aware the GPS DateTime must be UTC time!).
Any insights will be helpful.
Thanks

If it is one coordinate for all the files, then why not skip the csv file and write the values directly.
exiftool -GPSLatitude*=40.6892 -GPSLongitude*=-74.0445 /path/to/files/
Otherwise, you would have to have a time entry every half hour (1,800 seconds), but that can be changed by adding -api GeoMaxExtSecs=#### where #### is the number of seconds a image time stamp can be off from the GPS track's time stamp. See Geotagging Troubleshooting (https://exiftool.org/geotag.html#Troubleshooting) and Geotagging Options (https://exiftool.org/geotag.html#Options).
Thank you for the quick response and the great tips. Very very helpful and will save me a ton of work! I will look into the -api GeoMaxExtSecs option, which seems to be very intriguing.
Thank you for the links too. I keep learning more more of the wide wide world of options of Exiftool.
