dolphin screen print

the sort order by date photographed is not working because the fetched exif data is wrong or none existing, at least it is an empty field for dolphin

the exif data used should be "Original date and time"

These don't look like photos from a camera, more files downloaded from the internet.

I checked on files I grabbed from my phone (via Google Photos website) and they have the date captured.

Can you please confirm on photos taken from your camera or phone, thanks.

Status update.
Comment 3 Michael 2020-11-04 13:42:41 UTC
well, that's a pretty bad assumption ... I have no idea about cellphones but about professional câmeras I know a lot, this specially are from my SONY but the original date stamp is in that field I wrote before, but other cameras should have the same because EXIF data is a common standard
I don't know which data is actually queried because there are several, but only the "Original date and time" is which doesn't change by editing, copying or whatever

The assumption was based on the file naming. Most digital cameras have fairly standard naming with numbers for each photo.

Are you able to copy a freshly taken picture from your Sony camera onto the PC to test?

Does exiftags -i ~/Path/to/your/image.jpg show the "Image Created" date/time? 

You'll have to install this, it's a command line tool.
Comment 7 Michael 2020-11-06 10:50:47 UTC
wold be a good idea to install it together with dolphin when it depends on it ...

anyway it is the wrong date tag

the correct date tage would be "Image Generated" which you get with exiftags -a, image digitized often is equal to image generated but also can be later when there is any in-camera program running for whatever, also when sot in burst mode (series) then a lot of images might be buffered before going digitized  

all other not generated date tags could be change later after any digital manipulation in camera or computer

now what matters
even if I have exiftags installed it does not show the "other date" in dolphin like you could see in the last image I uploaded yesterday
Comment 8 Justin Zobel 2020-11-06 10:52:13 UTC
exiftags isn't a dependency of dolphin, it's just a tool I was using to confirm if the images are providing the data.
Comment 9 Michael 2020-11-06 13:02:03 UTC
ah ok then, if you need anything else let know
thanks

@Michael:

That "__IMAGES" / "fotos" directory ... is this a mounted network drive or a normal $HOME subdirectory?

Can you attach one of the photos to this ticket?

it is just another partition on the same HD
but I also use external drives

in a few minutes comes the image, I will send one original as it comes from the camera and the same picture edited, you can see what changes are between both
