Re: [darktable-dev] Geotagging module not working with dates < 1970-01-01
Hi Philippe, here are the results of the pending tests : * darkroom -> pattern for image information line : $(EXIF_DAY).$(EXIF_MONTH).$(EXIF_YEAR) • $(EXIF_HOUR):$(EXIF_MINUTE):$(EXIF_SECOND) • $(FILE_NAME) • $(MAKER) $(MODEL) • $(LENS) • $(EXIF_EXPOSURE) s • f/$(EXIF_APERTURE) • $(EXIF_FOCAL_LENGTH) mm • ISO $(EXIF_ISO) • Sterne: $(RATING_ICONS) • Breite/Höhe: $(SENSOR_WIDTH) x $(SENSOR_HEIGHT) px • Crop: $(CROP_WIDTH) x $(CROP_HEIGHT) px • OpenCL : $(OPENCL_ACTIVATED) gives the result shown in the attached screenshot. * ligthtable -> export to .../$(EXIF_YEAR)/$(ROLL_NAME)/$(SEQUENCE)-$(FILE_NAME) is working as expected, folder "1961" correctly created * checked exif information of exported jpeg : "DateTimeOriginal" is correct, modifications done with geotagging module correctly considered so for me it looks like there are no more issues. I support your idea to introduce a variable $(EXIF_MSEC) for the use case of images taken in burst mode. I agree with you that considering microseconds is not necessary.

Am 13.11.21 um 21:34 schrieb Coding Dave: darktable will never change the raw file but you might want to change the date taken exif information. I absolutely agree, darktable should never change the raw file. That's the reason why I use exiftool to rough adjust "DateTimeOriginal" of the raw files to the day the original (analog) image was taken *before* importing into darktable. So you might spend huge amount of work with darktable to correct the exif data and expect this to have a permanent effect. Now imagine you open the raw data with another program, then your tuning of date taken exif information does not show up. So it looks like you've lost the work. I'm aware of this situation. You will realize that you might have intended to change the exif in the image, not the sidecar information. That's exactly what I'm doing (see above). Where it is reasonable darktable is used only to fine tune the *time* information of "DateTimeOriginal". ___ darktable developer mailing list to unsubscribe send a mail to darktable-dev+unsubscr...@lists.darktable.org

I believe this is the right approach: darktable will never change the raw file but you might want to change the date taken exif information. So you might spend huge amount of work with darktable to correct the exif data and expect this to have a permanent effect. Now imagine you open the raw data with another program, then your tuning of date taken exif information does not show up. So it looks like you've lost the work.

Re: [darktable-dev] Geotagging module not working with dates < 1970-01-01
After replying to your mail I Just read your feature request https://github.com/darktable-org/darktable/issues/10398. As said, no problems at import, dates before linux epoch 0 show correct "OriginalDateTme" in "image information" module just as in the sidecar file. For the variables like $(EXIF_YEAR) I don't know. Unfortunately I'm not at my computer with the images at the moment, so I can't test. Will do this tomorrow and report to you.

Hi Philippe, yes, but I never had problems at import until now. The images of interest here are reproductions of negatives or slides, reproduced with a Sony DSLR. Of course they have "DateTimeOriginal" of the reproduction date/time (2019-2021). Then : * batch processing with exiftool, changing "DateTimeOriginal" of all images originally taken at the same day to -MM-DD 12:00:00 of this day * importing images into darktable (all images have "DateTimeOriginal" smaller linux epoch 0 at import) * selecting / processing / sorting / geotagging (if possible) * fine tuning time with geotagging module (if reasonable) exiftool handles dates before linux epoch 0 without problems and for the import module of dt I observe the same.
