Thread: Using Irfanview for redating, and re-orienting?

  1. #1

    Default Using Irfanview for redating, and re-orienting?

    I know there are other posts in this forum on this topic, but I haven't been able to implement the suggestions, so asking the questions as they apply to me.

    I'm looking for how to make Irfanview do two things I want/need:

    1. Redate files in Windows based on "date taken"
    2. Properly orient the image based on how it was taken

    Redate:

    Usually I transfer photos via an SD card from my camera, or a cable from my phone, directly plugged into the computer, and copying the files. This preserves the photo file date/time stamp based on when it was taken.

    But when I don't - for example, saving a phone picture to a cloud drive, then downloading - the date/time stamp will reflect when the file was copied, versus when the photo was taken.

    I used to use the Exifer program to mass-change the file date/time stamp to reflect the EXIF "taken" date. But this program is getting older and older and likely won't continue to run on future Windows versions.

    How do I use Irfanview to do this in a batch mode? What I desire is the image file remain unaltered, except that the date/time stamp in Windows is changed to match the EXIF "taken date."

    Re-orient:

    This was never an issue until I bought a Google Pixel 3a phone.

    Though Irfanview appears to work fine with pictures, including knowing how they're oriented, sometimes if I email them or put them on Facebook, the orientation is wrong - a portrait orient will render sideways like it's Landscape, or a photo taken with the phone upside down will look fine in Irfanview, but display in email or Facebook as being upside down.

    How do I use Irfanview to edit the EXIF data (or wherever this stuff is stored), so that a photo will orient as intended in email or Facebook?

    When you save a JPG after it is rotated to the right orientation in IrfanView, reset the Exif orientation tag.

    Can you take me step-by-step through this, including what setting to use? I know there are orientation tags in Exif data, but I don't know the meaning of their settings. Or how to access to Exif tags.

    The setting is on the Save as JPG dialogue.

    Okay, I see "reset EXIF orientation tag" - it's just a check on or off box. How does one use this?
