"Anthony Giorgianni"
Hello Terry
First, I apologize. I forgot to mark this thread in Outlook Express , and
I'm only seeing it now. I suspect I'm too late responding, but I'll answer
just in case (I'm emailing you as well since you're probably no longer
watching the thread.)
Thanks Anthony - no problem!
It is not strictly a viewer, though it CAN be used as one. (It includes
thumbnail and a slideshow capability) I use Irfanview for viewing, sometimes
MS Photo Editor. I assume you have downloaded Exifer 2, which is a bit
different than Exifer 1.
Yes, I have 2.1.5 (Build 263)
One question that's frustrating me is, what is the significance of
some thumbnails having RED data underneath (filename etc), and some
BLACK? I thought at first it was simply with and without full EXIF
data, but I have several which break that rule. IOW some black ones
which *do* have what appears to be full EXIF data (i.e. the Image
section is present), and several red ones which have just the Camera
and Thumbnail sections.
For backing up data, there is a "B" and an "R" on
the left side of the toolbar. Only "B" will be highlighted initially. Click
it to backup. The presence of a backup file with the same name as the photo
itself will allow "R" (restore) now will be highlighted. You commonly backup
before editing a photo using destructive software (software that eliminates
the exif data when you edit and resave - Adobe Photodeluxe and MS Pho Ed,
for example - a least some versions. Later versions of Irfanview do not
destroy Exif data. After you edit, you then can restore. You also can insert
the Exif data from one photo to another by backing up the data and renaming
the file. That's especially useful of you forget to backup, edit and save
the photo and need to recover the exif data say from a duplicate copy same
photo from a backup drive or perhaps from one still in your camera.)
Understood. Just tried that, and agree, it could be very useful.
Especially as in practice it seems difficult to avoid operations in
several popular programs which destroy the EXIF data.
The only part of it I'm interested in is the date and time, in the
Image section. (I'm staggered at how much else is available, and
frankly can't conceive who would want to use it!)
I had a folder of photos from a 4 day solo walking holiday along the
Thames Path and made a copy folder called \TP-Edited. One of the first
things I did was get my horizons and vertical straightened. Any for
which I did that (and the subsequent essential cropping) lost the
EXIF. I did this with IrfanView 3.95. I've just tried a test again to
check my recollection was correct, and it was. Here are the detailed
steps I took:
1. Opened the original image DSC00001.JPG in IrfanView 3.95. (If I
used Image>Information, or the shortcut <i>, I get to the EXIF info;
or go directly to it with <e>.)
2. I copied that image to another folder to work on it, opened it
again in IrfanView, and used Image>Custom Rotation to adjust the
verticals.
3. Then I cropped it to remove the inevitable triangular slices that
rotation causes, and saved it.
4. In IrfanView, I can no longer see EXIF info.
5. In EXIFER, in this temporary working folder, in the top left pane I
have 'Thumbnail not available'. The pane top right says 'No Data'. The
pane bottom right has no info, and under 'EXIF Thumbnail' it says 'Not
Available'.
So, I conclude that the latest version of IrfanView (3.95), *does*
destroy EXIF data.
I don't know why you're seeing this. If the exif data is available, there
should be a thumbnail - at least that's the case with my camera (an Olympus
2100UZ). Maybe that is a question for the rec.photo.digital group.
As tested above, it must be because the EXIF data was destroyed by
IrfanView 3.95.
Dunno. I've never seen that. Again, it may be something with
your camera. Or maybe it's a program problem that simply doesn't show up on
my end.
I gather that is the 'zero date'.
The thumbnail simply is a small view of the image as it currently is. The
exif thumbnail is the original. After you edit a photo and restore the exif
data, the exif thumbnail will be the original photo while the standard
thumbnail will be the current version. You can compare them to review how
you changed the original.
Understood, thanks.
