Sorting images by capture time

    You can sort by date, and this includes the time, if I remember correctly.

    Yes, sorting by date actually sorts by time of day too.

    What I do as a matter of course is rename images on import to a format including the date and a counter. So an image taken today (2nd April 2020) might be imported as 20-04-02-0023.NEF for instance. If I have been using two cameras I import from both, sort the images by date then batch rename in the date-counter format. The advantage of this is that image files can be sorted in the right order not only by Capture One putting them in date order, but also by anything else, such as a folder listing in the computer's file system. Batch renaming is really quick, so it's not a great burden to do that.

    Just to note that there is a pre-requirement to ensure that all the cameras involved have the correct times set. If necessary that might need to be accurate to the second.

    There is then the question of how Time Zones and more generic matters like Daylight Saving values are handled. Of course they may not be important for the purpose of the shoot if the primary need is for the order of the shots rather than knowing the precise time at which they were taken.

    Out of interest are current model cameras with built in (and activated) GPS facilities able to set their clocks by synchronising with the satellite system or do they, perhaps, just record the GPS time in a separate metadata entry without concern for TZs and DST? (Or not record GPS time at all?)

    I like your tendency for perfection Grant...

    It can happen, a video conference wedding in two different time zones  .. :-) for sure, different cameras would be involved  ... :-)

    Hi BeO,

    Hehe.

    I was thinking more about making sure the cameras were synchronised - especially if multiple photographers are involved.

    I have had a fair exposure, over the years, to real time service operations where Time zone considerations were quite significant for both operational needs and reporting or actual performance. It's the sort of thing that stays with you in principle even when the details of some of the situations fade from memory!

    I recall a client describing a problem they had making it easy for one of their customers to understand their performance reporting across a number of their sites which were located in northern USA somewhere around Chicago/Great Lakes as  I recall and enjoying a TZ change time line right through the operational area.

    Synchronisation came up again some years ago in a photographic context for a multi-camera shoot with around 30 cameras surrounding a subject in a studio and firing in sequence over a very short period.

    I don't usually bother about being too time accurate with the camera clocks. However with the DST clock changes I did check mine, especially a couple of older ones I have not used for a while. They were all pre-prepared for the changed DST settings but a couple of them were up to 3 minutes out on the base clock time.

    And of course if one shoots night shots around midnight the effects of the change of date could be significant.

    None of that worries me much but it sounded like it might, occasionally, be more significant for Mike (the OP).

    Hi,

    sorry but I photographed on 2 days with the same camera and part of the pictures of day 1 appear sorted as the last pictures.

    So what is your sort order set to? To get everything in time order, it should be by Date. (Maybe you already have that, but just checking.)

    Obviously. But it does leave the ones from day 1 in day 2. it seems to me it C1 does not recognize between PM and AM time. because the time is cronologically

    Strange - if it is done by Date, it should be in strict chronological order.
