Title: Adjust image capture time
Post by: photoj on October 22, 2024, 03:08:03 PM

Hi

I have a series of images where the camera's time was off by 43 seconds. I need to adjust every image's time stamp by +43 seconds. I'm on a MAC. Can someone suggest a command to batch process a set of images in a folder, overwriting the originals?

Thanks in advance for any assistance!

Jim

my best guess:

exiftool -shifttime '+::43'

I'm probably too new at this though!

The actual command depends on what date/time tags you want to shift. To shift everything (mostly), you would do this:

exiftool -time:all+=0:0:43 DIR

but that will reset the filesystem modification date/time to the current time. If you want to shift this too, use this command instead:

exiftool -time:all+=0:0:43 -filemodifydate+=0:0:43 DIR

Hi Phil,

Thanks for your help. Really appreciate it.

Getting 'no file specified'. trying a few different endings to the directory path - -ext png, %f.png. I tried a path to a specific file, but got the error fg: no current job. See below:

I believe its one or both of these fields that I need to update:

Date/Time Original : 2024:10:01 08:43:24
Create Date : 2024:10:01 08:43:24

You need a space before "/Volumes"
