[Bug 307053] New: Images sorted incorrectly

DrSlony-4
https://bugs.kde.org/show_bug.cgi?id=307053

            Bug ID: 307053
          Severity: major
           Version: 2.9.0
          Priority: NOR
          Assignee: [hidden email]
           Summary: Images sorted incorrectly
    Classification: Unclassified
                OS: Linux
          Reporter: [hidden email]
          Hardware: Gentoo Packages
            Status: UNCONFIRMED
         Component: Import
           Product: digikam

My photos are sorted incorrectly in the import panel (Import > USB Storage
Device > USB Disk "Digital Camera" at /media/disk). As a result of this, they
get renamed out of order, and this causes a headache, especially when shooting
HDR panoramas.

The photos in this screenshot, IMGP3285-9, were bracketed in 5 steps with 1EV
spacing between them (-2, -1, 0, 1, 2): http://i.imgur.com/XRl5A.jpg

Let's examine:

digiKam's import window shows the same values in the "Photograph Properties"
panel and in the "EXIF" (sic, should be "Exif") and "Makernote" panels.
Additionally, it also shows the following times in the "Camera File Properties"
panel:
IMGP3285.PEF - Date: 2012-09-19 12:26:38
IMGP3286.PEF - Date: 2012-09-19 12:26:40
IMGP3287.PEF - Date: 2012-09-19 12:26:40
I don't know where/how it got these times, "ls" and exiftool/exiv2 didn't show
them, but I don't think they're a problem.

Reproducible: Always

Steps to Reproduce:
Shoot a series of bracketed photos with a very short exposure time so that your
camera writes them all to the card in one go. Launch the import window in
digiKam.
Actual Results:  
Some photos will have identical times because exposure time was so short they
were recorded in the same second. My camera didn't mix them up while writing
them - the filenames reflect this, they are in order. For some reason, the
digiKam import window screws the order up, and so if I rename them on import I
end up with photos in the wrong order.

Expected Results:  
I expect the import window to list the files in filename order if the
timestamps are identical.

"Major: A major feature is broken"
I cannot use the import window at all until this is fixed, so it's a major
issue. For now I have to manually copy the photos and run krename.

By default, this time come from FS, not metadata. Why ? To collect quickly
items information from camera device.

I already solved this issue, through bug #246401

Solution : force digiKam to collect items info from image metadata. warning :
this can take a while. Go to Camera setup, and turn on right option (disabled
by default)

--- Comment #2 from DrSlony <[hidden email]> ---
Caulier thank you for looking into this, but unfortunately metadata time won't
help, because it's identical for shots that were shot quickly in series. That's
why I provided those exiftool/exiv2 results, unless you get the time from some
other place? The only way to keep the correct order that I know of is to have
that photo import window sort by filename, not by FS time or metadata time.

No. there is no better way to extract date and time from metadata. After all
it's stamp from camera device...

By default, Date and Time granularity is limited to 1 second in Exif.

There is perhaps a solution, if Markernotes as a better time resolution
information to use. But, of course, it's not standardized...

The Filename items filter mst be implemented in 3.0.0 beta1. Islam ?

--- Comment #4 from Marcel Wiesweg <[hidden email]> ---
If the (new, 3.0) model/view implementation is similar to the main view, the
filename will be used as second criterion if the primary one, the time, is
identical. It should, at least.
DrSlony: In the digikam main view, are the photos sorted correctly?

@Marcel comment 4
The photos are not ordered correctly in the import from camera window.
If I import the photos without renaming them and sort them by filename then
they show up correctly in the digiKam main view.
I have not tried to import the photos without renaming them and sort them by
date in the digiKam main view.
If I import the photos and rename them #### on the fly and sort by file name
then they will also show incorrectly in the digiKam main view.

Perhaps you can give us two photos which sort "B A" but should sort "A B" for
testing.

ad. comment 5:
If I import the photos without renaming them and sort them by date then they
show up correctly in the digiKam main view.
If I import the photos and rename them #### on the fly and sort by file name
then they will show incorrectly in the digiKam main view.
If I import the photos and rename them #### on the fly and sort by date then
they will show incorrectly in the digiKam main view.

So this is a more human explanation of what's happening:
1- Some photos have an identical date when shot quickly in succession.
2- They are stored in the correct order on the memory card because the number
in their filename is incremented in the correct order.
3- digiKam's Import window lists them in the incorrect order, which means it
does not sort them by filename.
4- When imported without renaming, and the album is sorted by name or date,
they are shown in the correct order. This means that when they are sorted by
date and the date of two or more photos is identical, then digiKam falls back
on the filename (which is good).
5- When imported with renaming to ###, they are numbered in the same incorrect
order that they appear in in the Import window. When I sort by date, the order
does not change. This is weird. Why would sorting by date show them in the
correct order in point 4, but not here?

Here are 6 sample photos for your enjoyment [54MB]:

--- Comment #8 from Marcel Wiesweg <[hidden email]> ---
In the 3.0 import window, your six sample images in a short test are sorted as
the file name sequence number suggests, regardless if I sort by date or by
filename.
Your comment 7 refers to 3.0 as well?
