Geotagging question
I'm going for a journey during which I will travel through a number of time
zones. For the first time I will bring with me a GPS-logger (and a DSLR - of course). Somewhere I have read that it is recommended to leave the camera-clock at home-time - in order to minimize tagging troubles/mistakes when tagging the photos after the home-coming. On the other hand, such a practice will have my photos tagged with times that are not true w.r.to local time. Anyone having experiences in this matter? BrJohan |

I don't know about the tagging issues, but I always prefer my pics to show the actual local time where the photo was taken. |

I use it with the logs from my Garmin and it works great! It suggests that you sync the clock in your camera with the GPS, but also allows a time offset variable if you forget.

BrJohan Oziexplorer GPS software has this feature, you can download and trial the software to see if it meets your needs and should tell you what time needs to be set. |

I don't know about the tagging issues, but I always prefer my pics to show the actual local time where the photo was taken. With Geotagging though the GPS and the camera need to agree otherwise the software used for placing the photos at the right place will not work correctly. GPS's can be set to display whatever time you like, the camera can be set for any time you like but if they are different then the tagging will be somewhat off!! |

BrJohan After reading the previous lists, I think your best option may be to buy a camera with gps built into it and keep everthing in 1 integrated unit that shows you position, direction of view, angle of view, etc. Then, if you want, you can just change the time on the camera to whatever you want. |

GPS's can be set to display whatever time you like, the camera can be set for any time you like but if they are different then the tagging will be somewhat off!! Generally, the position log data saved by a GPS logger will have the time stored as UTC. If you're using a handheld GPS that provides a display and a user interface, you can set the time zone displayed, but the logged data is still UTC. So the conversion between camera time zone (stored in the EXIF data) and the always-UTC logged position data has to be done by the geotagging program. So, you have to make a decision. You can 1) leave your camera set to UTC all the time 2) leave your camera set to your own time zone all the time 3) adjust your camera's time zone to match local time Choice 1 means you never have to change any settings, not even daylight savings time start/end. You never get photos tagged with the wrong time, and your geotagging works without thought. But all your photos have EXIF dates that are UTC, so you mentally have to convert to local time using whatever offset is appropriate for the place and time of year they were shot. Choice 2 is only slightly more work; you need to change your camera time and the geotagging program's offset twice a year (if you observe DST). Locally-shot photos have local-time EXIF data. And photos shot in other time zones have incomprehensible date stamps. Choice 3 means all your photos have local-time EXIF data (in theory). When you geotag the photos, you have to set the correct UTC offset for each batch of photos, and have to separate photos from different timezones into different batches. So it's more work. Also, in my experience, you need to spend some time fixing the time in photos that you shot with the wrong time set in the camera. This makes it even more work than the other two methods. I currently use #3, but I keep thinking about changing to #1. I don't look at the EXIF date info that often, so mentally converting it from UTC isn't a big deal. Always having the dates and tagging right is a big plus. The thing that holds me back is that I use Breeze Downloader to sort the images into one directory per day, and the sorting is done on the basis of the EXIF data. If I want the directories to reflect local-time days rather than UTC days, I have to move a bunch of images manually into the correct directory. Dave |

BrJohan I'd strongly suggest you always place your camera on local time and use software that supports this practice. If you do not do this you may end up very confused about some of your photos in the future. In particular this applies if you are traveling through asia/pacific regions where there might be international date line issues. One experience I had involved setting the time in one camera, but forgetting to set it in another camera. I was in Asia and it was new years week. This was a worst case senario, but needless to say the time on some of the photos I took ended up being somewhat in question later when I reviewed them. Not to mention being heavily jet-lagged, imbibing, or other factors that may influence your ability to reconstruct your trip from home base. |
