Custom EXIF Date

simor · 2009-08-30 17:41

First thing thank you for such a great application! I've been using it to rename my photos using the EXIF date for almost a year. Lately I got some pictures from a LG moile phone which have the date in EXIF stored in a different format eg.: 24 Aug 2009 15:30:18. When I use the EXIF_Date tag name in Pascal script I'm getting an empty string but I know from Irfanview that the tag is there. Is there any way to retrieve the date?

I know very little about pictures tags, but it seems strange to me that someone would like to go against the standard.
Try to check if you haven't cleared the Data Format in Renamer Settings.
But if you would do that, then you wouldn't be able to retrieve date from all pictures, not only the LG mobile ones.

Hi simor!

Welcome to the board.

Have you tried the new Rearrange rule (in the latest beta)? It may serve your need by letting you use the EXIF date meta tag in any pattern you want.

The rule is explained in help, here: http://www.den4b.com/wiki/ReNamer:Rules:Rearrange

This would be useful in case the script is not working with the EXIF tab format and you are not sure where the problem is...

Thanks for such fast answers

krtek, it's very weird for me too and very frustrating as I've been trying to get it working for a few hours and also tried another software which reads the date but cannot use it in any way as there are parsing errors. If it reads it then it must be stored as some string - ? Then maybe Renamer can read it as string too?
Somehow I have missed the settings you mentioned, but I checked them and they are with the correct (by spec) format. I changed it to fit mine: dd mmm yyyy hh:nn:ss but there is no difference in result. Weird I thought this was the reason why Renamer couldn't read the date. Am I doing something wrong?

narayan, no I haven't... I just got the beta and read the wiki page but I don't know how I can use it The problem is that Renamer won't read the date field *at all*. Also when I switch the EXIF Date column then it shows empty. I wrote a little pascal script to format the date from a standard exif tag exactly as I want it so this is not a problem if I could only get my hands on the string data (which Renamer returns as empty string).

Well, I was wrong...
Maybe this thread might be a little help for you...

Well, I'd be happy to recreate the dates to fit the spec-format if I only knew the way to read them first from the tag.

I guess you will have wait for Denis to help you.
But for now, would you be able to provide sample of your LG photos tags done eg. with Exiftool.exe like in the thread I pointed to earlier?

Ok, If you had your hands on the script already this might help you. If it won't, there is one more.

Just use
'Create Date\s*\:\s*(.*?)[\r\n]'
or
'Date/Time Original\s*\:\s*(.*?)[\r\n]'
in the line

TAG = 'Image timestamp\s*\:\s*(.*?)[\r\n]';

PERFECT! Thank you so much, this is exactly what I was looking for

p.s. I had to use 'Image timestamp' as this is what exiv2 uses.

Dzięki i pozdrawiam!
