EXIF Date Quesiton

[zoliky]

Hi,
I would like to replace this date:

3/2/12

with

3/1/12

Due to February month something happened in my camera and the date in my camera is one day ahead.
So, I would like to have 3/1/12 instead of 3/2/12



Can you provide me the Exiftool parameters to change both? Please I would be very grateful. Thank you!

I'm using a Nikon D3100 if this helps.

Hi,
You can decrement day in Date Time Original by using:
exiftool -DateTimeOriginal-="01 00:00:00" *.jpg
..which changes Date Time Original value on all jpg files in current directory.
To increment Date Time Digitized, you use:
exiftool -CreateDate+="01 00:00:00" *.jpg
