Is there any way to view a photo's entire history? Sort of like a fingerprint of some sort. I know about the File Info option in Photoshop, but I'm looking for something more advanced.

I remember someone did something similar with the Anita Flick photos that pretty much proved they were real ... It traced the photos back to her Web site.

maybe, I'll give it a try

The hex information just showed that it may not have been fed into photoshop. There was by no means conclusive information about where the photos came from or rather or not they had been edited.

yeah, you can see what programs have opened/saved a certain image, but that's it.

^ Assuming that the programs modify the file headers/meta info and that the headers or meta info hasn't been edited.

the pictures were real

9/7/2007 9:40:41 PM

And the info tracking them back to the website was the ~300-1000 wolf webbers who clicked on the original links to her AOL account to view the pics.

Then later it was a screenshot of the directory of her AOL account showing an index with all the pics.

But uh, yeah... What specifically are you trying to do? Maybe tww nerds can point you in the right/another direction.

9/7/2007 9:57:43 PM

oh, it was her AOL account? i thought it was her university account.

I'm trying to figure out when a photo was taken ... assuming it was a digital camera and not just scanned ...

9/7/2007 10:23:50 PM

there are programs that can tell you that...
my co worker has one.

^^ check the EXIF info.

9/7/2007 11:28:12 PM

you can build a EXIF data parser very quickly. like in 5 minutes or less.

just download these two zip files and extract to your local drive

LIBEXIF: http://downloads.sourceforge.net/libexif/libexif-0.6.16.tar.gz?modtime=1181664577&big_mirror=0

and

EXIF: http://downloads.sourceforge.net/libexif/exif-0.6.15.tar.gz?modtime=1179919542&big_mirror=0

open a command window, CD into your new LIBEXIF directory, type "configure" then "make" then "make install" (if you're using windows, you'll need to do substitute "nmake" instead of "make")

then CD into the EXIF directory, do the same process as above.

when youre done, in the EXIF directory there will be an EXIF executable that can be run from the command line that will display all your EXIF data. the real power, of course, is that you can use the LIBEXIF to write your own C/C++ routines.

9/8/2007 2:11:17 AM

^ That's a little overkill, don't you think? IrfanView will show EXIF info.

9/8/2007 2:50:33 AM

I dont do Windows.

(i guess i should mention this assumes you have a C/C++ compiler installed on your machine. If you're using Windows should at least get the free Visual C++ compiler from Microsoft ... http://msdn2.microsoft.com/en-us/express/aa700735.aspx )


but yeah, I actually forgot about IrfanView. that was a pretty cool application. everything could be driven from the command line, so it was a great out-of-the box solution for batch photo processing.

if building C/C++ programs from source is too intimidating, get the IrfanView binary: http://www.irfanview.com/

the EXIF build i described earlier, runs from the command line like this
