Hi all,

When I view digital camera pictures on my computer, it show's the 'date
picture taken' tag amoungst other info available. I have recently been
scanning negatives into my computer and would like to edit this tag manually
but can't find any way to do it. I've tried going via 'properties, summary,
advanced' but the tag isn't there to be edited Does anyone know how to
manually edit this tag?

Thanks for any help,

Matt.

Digital camera makers attach a file (EXIF file) to each photo file (JPG)
that contain the information you described.
When you scan a photo you also get a JPG file but there is no way to attach
an EXIF file to it. However you can add info to this file when you via
properties, summary, advanced, comment. You can also use some free software
like:
www.picasa.com
that will allow you to add comments to you files.
 
Actually, the EXIF data is not a separate file, but is embedded in the
JPEG file. And there are editors that will create EXIF extensions in
JPEGs that do not have them.

JPEG "properties" editors are editing the EXIF data.

If you know of software capable of creating an EXIF file for a JPEG file
created by a scanner, please let us know. This is what the original poster
would want.
As far as I know, Exif is a specification for image files used by digital
cameras to add tags (date, settings etc.) to the image and we normally call
this additional info an EXIF file. Yes, plenty of software to edit such a
file but I don't know any to create it outside of a digital camera. Maybe
there is.

Sure - Try Graphics Converter Pro. It's the only one I can find that
will allow you to add EXIF data to a JPEG where none exists.

BTW, Picasa, as feature-laden as it is, cannot create EXIF data in a
JPEG file which contains none.
 
EXIF is nice but it is easily destroyed. Try copying a jpg to Win98 PC and
back to WinXP. I think you will find the EXIF data is gone.

I just discovered IPTC data. I'm not quite sure where it is stored but seems
similar to EXIF. It is not destroyed by copying the jpg to a floppy or thumb
drive like EXIF data is. You can create IPTC data with XnView.

Exifer will both edit and create EXIF data *within* a JPEG file.

Contrary to what some others have posted, copying a JPEG file has *no*
effect on its embedded EXIF information. EXIF information is preserved
by most (but not all) image editing programs, so that is a potential
problem.

When copying a jpg with EXIF data to a thumb drive under Windows 2000 it
says something like "the file has additional data which will be lost. Do you
want to continue?". It does loose the EXIF data. It does not delete IPTC
data.

I suspect you are seeing the following dialog:
"The file "thumbs.db" has extra information
attached to it that might be lost if you continue
copying."

Have a look at the following article for info on
thumbs.db:

Its not the thumbs.db but whatever contains the data added from Windows
Explorer right-click properties. The warning is as follows:

The file 'xyz.jpg' contains more than one data stream, but the destination
volume does not support this feature. Some data will not be preserved as a
result.
Information that will not be preserved includes: Document Summary Info.

The more I think about it Mr. Mahon may be correct that EXIF data is not
lost by copying a file. The above may be something MS Windows provides.

Maybe that dialog is because you are
copying from an NTFS volume to a
FAT volume.

The following article (even though it refers to
Win2000) contains info about Data Streams
in relation to NTFS and FAT.
