Help with Flickr Photos

[Vikas]

I have close to 26,000 photos and videos in Flickr which are arranged in about 100+ albums. I downloaded one of the albums and observed that all of the EXIF data is intact except the 'created' and 'modified' date/time is changed to the date and time of downloading the particular album. I intend to change these fields to the original 'create' date. I need help with that.

Further, my idea is to do this album by album. Download the album and content thereof in a particular folder. Run the script to modify the create date and then move the folder to another destination directory / folder. Can I create the folder in destination directory/folder with the same name as the album name on Flickr.

Appreciate the support !

Meant to add that there are videos along with pics in the folders/albums. I am assuming that tag for original create date for photos will be different that from pics?

Sounds like that's the file system data, not the EXIF data.  So you would want to copy the EXIF timestamps to the file system timestamps.  Try this
exiftool "-FileModifyDate<DateTimeOriginal" "-FileCreateDate<DateTimeOriginal" /path/to/files/

Meant to add that there are videos along with pics in the folders/albums. I am assuming that tag for original create date for photos will be different that from pics?

Video timestamps are a bit more complex.  According to the spec, the timestamp is supposed to be in UTC, but not all cameras will record it as such as they may not know the timezone. For a video, the command would be the same except you would most likely want to use CreateDate instead of DateTimeOriginal.

If you know the video didn't come from a source like a cell phone which would be aware of the time zone, then you would try
exiftool "-FileModifyDate<CreateDate" "-FileCreateDate<CreateDate" /path/to/files/

If the above command is off by the timezone, then you would want to add the -api QuickTimeUTC option
exiftool -api QuickTimeUTC "-FileModifyDate<CreateDate" "-FileCreateDate<CreateDate" /path/to/files/

Thanks Star Greek.
I am a Mac user. The below mentioned command did not work for me - I tried by giving the path to folder and path to file.


vikassinghal@VIKASs-MacBook-Air ~ % exiftool "-FileModifyDate<CreateDate"/Users/vikassinghal/Flickr/2015\ Sep\ Parul\'s\ Birthday/20150919_214104_21554971791_o.jpg

OR


vikassinghal@VIKASs-MacBook-Air ~ % exiftool "-FileModifyDate<DateTimeOriginal"/Users/vikassinghal/Flickr/2015\ Sep\ Parul\'s\ Birthday
No file specified

I would like to run the command at folder lever to apply on files/pics in that folder

You've missed a space between the argument and the filename.  I thought you'd need to change the " to ' but I tried it and apparently not.

You've missed a space between the argument and the filename.  I thought you'd need to change the " to ' but I tried it and apparently not.

I believe it's necessary when there's a dollar sign to avoid interpreting the tag name as a shell variable.  This is a direct tag copy without any extras so it shouldn't be necessary.  But I would consider it a good habit to be in for Mac/Linux anyway.

Thanks for your advice and suggestions. I am getting there but not fully.

I am going to be more descriptive in order to get the correct the command line that I can execute towards my objective.

Here I go -

1 - I have created a folder (Lets call it "Folder 1") which has download of all the contents from one of my Flickr Album and which is saved in the path "User/Vikas/Photos")
2 - This folder contains the following 3 files - "File 1.jpeg", "File 2.jpeg", "File 3.mov"
3 - I now want to change the value of "File Modification Date/Time" and "File Access Date/Time" to "Create Date"

Given above, how can I execute a command to accomplish the above. I want to avoid doing this for individual files in the folder. I would want to accomplish the stated outcome at folder level.

Please can you provide me the command line. Thanks much !

You can set the FileModifyDate using the command that Alan gave, but specify the directory name instead of the file name.

You can't set the FileAccessDate.
