Camera time error correction.

[GKirkaldie]

Here's one I ran into recently..

I auto-imported some pictures and got an error that a few pics weren't added since they had no time/date match. Weird, but there could have been a reason.

Then I looked at the graph and noticed that some pictures I had taken were at the wrong depth. It was a V shaped dive, and the same object was at 50' and 70' on either side of the V..

So I deduced that the time must have been off, sure enough there was a few minutes difference between the dive computer and the camera clock. I deleted the photos and edited the time stamp of the photos then re-imported, everything was fine, and the original ones that didn't get imported were now imported, and the other pics were now at same depth.

So, if I had known the two clocks were off and there was a function to add an offset into the import dialog, everything would have been fine.

Best solution, make sure the 2 clocks are in sync before the dive

This has been mentioned before. I would like to add maybe a slider to adjust the camera time by X minutes or something like that.

I second the idea of a slider or something that I can adjust on both the entire photo set and on a per-image basis if possible. I often find myself combining images from two or more cameras from others in my groups, and trying to get all those cameras in sync before a dive just doesn't happen. If I had to choose one feature though, the slider that moves the entire photo set forward/backward in time would be fantastic.

It's pretty straightforward to apply an offset to the match - I have two dates that I'm comparing so it is simply a matter of adding some number of minutes/hours to one of them before the comparison.

The real trick here is how to include it in the UI nicely and make things easy to use. I will have a think on how to incorporate it (not for this update unfortunately) and see what I can get going.

This is the dialog from HoudahGeo...


Something similar maybe. With this dialog, I just hit enter if there is no correction

[nick]

Ah cool, yeah. Something along those lines would do the job nicely.

I'd actually like to enhance the overall support for images so you could include captions, too.

Ok.. I couldn't sleep. So I added something in for this. When you open up the auto-add panel, you will get the option to apply an offset for hours, minutes and seconds.

It's not ideal - if you didn't know the exact offset then there would be a bit of trial and error with adding the images and changing it, then retrying. But at least the basic option is there, and less annoying than manually changing a bunch of dates in the EXIF.

what would happen if all items were put to UTC and then location correction entered for the time zone dives were done in ? Example would be to set my computer / camera to UTC and then on each trip I could enter the local Vs. UTC time. Depending on daylight savings here in the USA ?

[nick]

Probably not much. It's just a basic offset/adjustment.
