Code:

Hello

I'm trying to change a bunch of photos, but first I'm just trying one photo because I'm running
into an error and am not able to change the date taken. Below is the syntax and error.

C:\Users\thebill\Pictures>exiftool "-DateTimeOriginal+=0:0:0 7:0:0" IMG_1948.jpg
Warning: [minor] Adjusted MakerNotes base by 4162 - IMG_1948.jpg
Error: [minor] MakerNotes offsets may be incorrect (fix or ignore?) - IMG_1948.jpg
    0 image files updated
    1 files weren't updated due to errors

Any thoughts anyone?

The image has likely been edited by some other software which
has corrupted the makernote offsets.  You should try this command
again but try adding the -F option to attempt to fix the
offsets, and repeat with the -m option to ignore the problem.
Then compare the output of exiftool for each case to see which
way works best.  In Unix, the commands to do this would look
something like this:

Code:

cp IMG_1948.jpg test.jpg
exiftool "-DateTimeOriginal+=0:0:0 7:0:0" -F test.jpg
exiftool -a -u -G1 test.jpg >test1.txt
cp IMG_1948.jpg test.jpg
exiftool "-DateTimeOriginal+=0:0:0 7:0:0" -m test.jpg
exiftool -a -u -G1 test.jpg >test2.txt
diff test1.txt test2.txt

Or, if you prefer, you can send the image to me (philharvey66 at gmail.com),
and I will take a look at it myself.
