How do I keep CS-2 from modifying the Original Date & Time the picture was actually taken? (EXIF Data)

Procedure I’m Using:
I open my RAW image file via Adobe Bridge. I adjust the exposure settings and open in CS2.

All I usually do at this point is apply the Unmask Sharpening filter. Then I save the image as a TIFF file.

When I go to print the image (and view the properties) and choose to have the Date & Time Stamp put on my pic’s, I notice the Date & Time has been changed to when the RAW file was Saved as a TIFF!!

Jack, I just tried those steps on a picture shot last March. Here is what my metadata look like: < http://www.pixentral.com/show.php?picture=1SRuQKYmPKJdIyG2lV 1os2mjQPjcg0> As you can see, the "Date Created," "DateTimeOriginal," and "DateTimeDigitized" stay set to the original date.

What are you doing to put the date and time stamp on the picture? Perhaps the script you are using for this is taking the file date and time rather than the correct metadata.

I’m using a program call QStudio to print my TIFF images. Very nice program!

The properties of the TIFF file show the date & time I modified the RAW file (saved RAW as TIFF). I guess I should expect that.

I was hoping there was a procedure where I could have kept the original Date & Time from my RAW file over to my TIFF file.

Any suggestions?

It sounds like QStudio is using the file date and time, rather than the EXIF DateTimeOriginal data. One solution would be to use a utility to change the files’ date and time. There are lots of free utilities that do this; some examples are TimeStamper for Developers < http://www.softpedia.com/get/Programming/Other-Programming-F iles/File-TimeStamper-for-Developers.shtml> and Touch Utility <http://tp.lc.ehu.es/jma/win32/touch.html>. I haven’t tried these, but they should do what you are looking for. Give one of them a try.

So your not aware of any way to keep PS from changing this? I usually have batches of 75 to 100 pics to print, and rectifying this problem from the beginning would be the best solution.

Surely, as complex as CS2 is, this would be available or achievable.

What I would like to know is are there any other people using PS to process their RAW images and save them to jpeg or tiff and ever needed to print the dates & times when the actual shots where taken? And if so how do they do it?

Jack,
As was pointed out in your other, duplicate thread, PS is using the file create time to log the time the file was created. This is not the same thing as the time the image was created — it’s an entirely separate field in the file.

These are two unrelated pieces of information that each reside in dedicated fields in the meta-data.

But the bottom line is PS isn’t doing anything to the file. You’re creating a new file, the TIF, and the operating system is correctly recording the time you created it.

If you want to record the time the image was created in "child" copies of your RAW, you need to write the info in the the appropriate meta-data field, not the "file created field."

Where do you suggest i get this information?

Jack,

I can tell you where it is, but I don’t know how, programmatically, to access it. I believe there is a PS forum for programming though, and someone in that forum might be able to help.

To see it, open your RAW file. File > File Info. You want to snarf the create time and copy it to the IPTC Date Created field. The IPTC data _should_ be carried forward into other derivative copies of the file.

Other ways to do it would be to explore 3rd party raw file tools. I can’t sweat to it because I don’t have the software on this computer, but I think Nikon Transfer (out of Nikon View) allows you to do stuff like this when it copies raw files off a camera. I’d be surprised if other software didn’t too.

You may want add this to the list of "Feature Enhancements" for PS or Camera Raw…
