There is only that one source of information, so if that's not being used then 
something is wrong. Do you see your 1978 timestamp in the image information 
module on darktable's left side? If yes, please upload one such image file for 
me to try.

before importing, run:
  exiv2 mv \-k \-r %y%m%d_%H%M%S_:basename: \.\/*.{nef,jpg}

your filenames with then be something like:
  170914_191832_pt2_8177.nef

  YRMODA_TIME_filename-from-camera

and you will have the exported images with the parameters you wish.

Thanks, I'll start working with that. It's kind of "yellowie" (if
that's a word). Hopefully I should be able to tone it down more.

[darktable-user] Issue with timestamp on export

2017-09-15 Thread Frank J. 
Hi,

for sorting the exported JPGs by year and month, I want to include the
timestamp, when the picture was taken, into the filename on export.

The templates "$(EXIF_YEAR)_$(EXIF_MONTH)_$(EXIF_DAY)" from
http://www.darktable.org/usermanual/ch02s03s12.html.php seemed to be
right for this.
This works fine for pictures (RAW, JPG) that were taken with digital
cameras.

But my DT-archive includes 40 years of work since I scanned all my old
slides with a NIKON Coolscan 4000 ED.

I found, that I have to set for example
 $ exiv2 -M"set Exif.Image.DateTimeOriginal '1978-09-01 00:00:00'" \
   dia_f037_b0[1-9].jpg
BEFORE I import the scanned JPGs into DT.

Not "Exif.Image.DateTime" but only "Exif.Image.DateTimeOriginal" sets
the right timestamp in the database-column "images.datetime_taken" on
IMPORT.

But for this scanned pictures the templates "$(EXIF_YEAR)" etc. on
EXPORT do not work.
It seems "import" and "export" use different exif-time-values.


How can I use the values from the database-column
"images.datetime_taken" for the filename on export?

Hi,

maybe try the sepia styles at dtstyles.net?
I'm not into sepia, but there are different options for this on that site.
The preview on this "Platinotone" one looks good, IMHO:
https://dtstyle.net/index.php/i/281

Cheers

DT 2.2.5 on arch.

How to make sepia?

I've tried using the colorize after the monochrome. I only ended with "puke
yellows".

Any hint/direction?

Thanks

I finally made a new build, and the problem was fixed.

Thanks.

What is wrong with this style?

Running Darktable 2.3.0+917~g4833a95

Exported images (jpeg, tiff, etc.) are a black square, no image, no nothing.

Please run darktable from a terminal and check for error messages there when
exporting with that style. If nothing shows up try adding "-d nan" to the
darktable command and see if that shows any problems.


Best regards

Yes, it's a pity that EXIF is quite bad in that regard.

Timestamps should already be displayed as-is.
What operating system are you on? What version of darktable are you using? And 
could you please share a sample file, together with what time you'd expect to 
see for it? I think I saw issues like that in the past but can't remember 
details.
