Dates of the EXIF - how add/edit using exiv2... is there a better way?

Hello world!

INTRO: I'm new to Lightroom. I went through a few books and a lot of tutorial on lynda and youtube, so I feel very uncomfortable with the LR 5 import process. This post and the issue is a matter of pre-importation / organizational.

I have more than 30,000 photos old, digitized (scanned) which dates back to the 1950s. Of course, most are taken with older, analog devices. They are now organized in folders by date.

AIM: I want to import those pictures into LR and be able to find the dates of metadata (Capture Date & time).

PROBLEM: Of course, scanned old (or even more recent manipulated) pictures often do not have the correct creation date of EXIF information. Worse, many (or most) of these old images don't even have a date field EXIF!

What I've LEARNED: Immediately to use exiv2 file name or name file evix2 - pt indicates whether it is or is not info date for the photo. Otherwise, exiv2 - pt filename shows nothing. If there is a date field EXIF, it will be shown.

For all these pictures with no date field, if I import them into Lightroom, there is of course no date information that is displayed in the Panel (by default or EXIF) metadata, and you can change the date (because the field is not there).

If exiv2 - pt filename indicates the field of Exif.Image.DateTime, then in Lightroom, you will see the time of Capture and Date of Capture fields, and you will see an icon to the right of these dates, which allows you to change this date.

Exiv2 - pt filename if no IS NOT this Exif.Image.DateTime field, you can ADD this domain by using the command line:

"" exiv2 - M ' Exif.Image.DateTime 1965:01:25 15:45 Ascii value "file name (or whatever your time/date).

Now, if you import this image in LR, you will find the fields Date of Capture and capture in metadata > default Panel... AND you can change them if necessary. In other words, the command above-M exiv2 added the date field EXIF than LR needs to search by date.

WHAT is MY point of VIEW, AND WHAT the QUESTION is? I have no problem using exiv2 for add/edit an EXIF DateTime field creating a folder at a time prior to importation in LR. This will allow me to search on these date fields *.

My question is this: is there an easier way?

Surely there must be dozens (hundreds?) of thousands of photographers 'old' like me who have found old photos with incorrect fields EXIF creation date or missing the date on the ground completely (in which case, as I said earlier, can not be added/edited using LR, PS, FileMultiTool, Graphic Converter, etc..).

I realize that I could look at images based on file names or file, or I could enter dates in tags, but these methods to find images are not nearly as practical the use of metadata. So, if I know that an image was taken in June 1962, then I would like to that metadata EXIF to have this info so that I can get on this subject. Have no field of EXIF date or have a date field that is incorrect is useless.

I would love a LOT YOUR FEEDBACK! If there is a way easier or better, I'd love to help you! It is has so many photographers experienced on this forum, and more than probably a lot of them have old photos with the date fields incorrect or missing EXIF they brought in LR.

Thank YOU! I'll appreciate really any help you can offer.

* there are other EXIF date fields that can be changed using exiv2: Exif.Photo.DateTimeOriginal , Exif.Photo.DateTimeDigitized , etc. But the main date that LR uses to search for files is described above.



P.S. I also tried jhead-filename ds1965:01:25 (or whatever your date) to change the date. This only works IF there is already a date field this EXIF. Otherwise, jhead will report an error and not create a. Exiv2 - M will create the field.


When I put the date and time for about 10 pictures, menu option assigned LR (seemingly random) time to each of them. Why LR do this? I can see perhaps compensate for each photo in 1 second (00, 01, 02,...), but simply assign random times makes no sense at all. At least in testing, I have just done, LR did not pass during the same amount, but totally affected times (randomly?) to each photo.

Normally, when you change the time of the capture of several photos, LR shifts each picture the difference between the time that you register and the time of the most selected photo.

I suspect you're tripping over a bug known to the LR with digital photos that are EXIF:DateTime but not EXIF:DateTimeOriginal.  In this case, LR indicates a time below the thumbnail, but uses the other for its internal capture time.  In this case, things can get very confusing.  The best way to clean, it's to make sure that all your photos are EXIF:DateTimeOriginal before you import it.
