EOS-350D filename variations
no-s...@lycos.com
Canon EOS-350D (Rebel XT) I'm puzzled by the variations and seemingly
duplicate copies of the same photos. Perhaps someone can clear up the
confusion? I don't want to import duplicate copies into iPhoto, and
neither do I want to delete files that I should keep.
Just for the record, I'm set my camera up to shoot simultaneously
JPG+RAW.
I'm viewing the photos directly on my Mac (MacOS 10.4.8) desktop by
opening the DVDs there.
Here's my first example of a naming scheme where the same photo comes
as a "group" of 4 separate files:
Naming scheme 1:
---------------------------
IMG_2597_1.CR2 (9.160154 MB) landscape thumbnail
IMG_2597_1.JPG (2.612278 MB) landscape thumbnail
IMG_2597_3.JPG (2.115624 MB) portrait thumbnail
IMG_2597.CR2 (9.212525 MB) landscape thumbnail
This pattern repeats itself with the rest of the photos on that DVD
although the filename ending with "_3.JPG" sometimes has a thumbnail
orientated in the portrait direction and sometimes in the thumbnail
direction.
Note that I'm talking here about the *direction* of the thumbnails on
my computer desktop, not actually the photographic content that it
displays.
I emphasize this because there seems to be some distinction between the
thumbnails's direction and the way the photo has been taken (by looking
at the actual picture on the thumbnails). I can see two variations
(where the * denotes "IMG_" and a number):
IMG_5312_1.CR2 landscape thumbnail landscape photo
IMG_5312_1.JPG landscape thumbnail landscape photo
IMG_5312_3.JPG landscape thumbnail landscape photo
IMG_5312.CR2 landscape thumbnail landscape photo
and:
IMG_2597_1.CR2 landscape thumbnail portrait photo
IMG_2597_1.JPG landscape thumbnail portrait photo
IMG_2597_3.JPG portrait thumbnail portrait photo
IMG_2597.CR2 landscape thumbnail portrait photo
Could any of this have to do with the "Auto rotate" function in the
camera switched on or off?
Naming scheme 2:
---------------------------
The pattern with a group of 4 files of the same photo (above) repeats
itself for almost all the photos on the DVD, but all of a sudden I just
get groups of two files with the same photo:
IMG_2738_1.CR2 landscape thumbnail landscape photo
IMG_2738_3.JPG landscape thumbnail landscape photo
with a different variation:
IMG_2739_1.CR2 landscape thumbnail portrait photo
IMG_2739_3.JPG portrait thumbnail portrait photo
Naming scheme 3:
---------------------------
The last variation is simply the filename without any "_1" or "_3" at
the end:
IMG_6672.JPG
IMG_6672.CR2
There might be others as well, but these are the ones I've taken notice
of.
So why all the variations, and why are there seemingly identical copies
(albeit with slightly different file-sizes) of the same images (naming
scheme 1)?

Only the last one is from the camera. It doesn't put _1 or _3
in filenames, ever. Whatever software you're using to manage, edit,
copy, etc. these files must be adding these extra characters to
distinguish between different versions of the same file.

Hmmmm... interesting.
I wish I remember how I imported the photos to my computer, but I
can't.
However I'm almost certain that I opened up the memory card on the Mac
desktop, created an empty folder and dragged the contents over. From
then on I burned the newly created folder (with the photos inside) to a
blank DVD. Finally I dragged the contents of the folder over to iPhoto,
which might change the file-names, but as I said I burnt the DVD from
the desktop, not iPhoto.
Anyone with a Mac know if the operating system somehow messes up my
files?

Have you looked to see if the camera is recording in RAW+JPG. This will
create 2 files with the same filename. Or, have you done any post
processing on the computer and saved the file with the same name and
different extension.
These 2 reasons are why you have duplicate names.

Yes, that's what I said. I have my camera set to shoot RAW+JPG. But
that should only create one JPG file and one RAW file. So what's the
deal about the _1 and _3 in the names?
Or have I misunderstood and you mean that the camera create 2 JPG files
and 2 RAW files with the same name if you shoot in RAW+JPG?

Nope.

I suspect your (presumably homegrown) backup procedure is the cause.
In some cases, Mac OS X will automatically append _x to the filename of an
identically-named file being placed in the SAME folder rather than
overwrite/replace the original file.
Those files without the appendage are the originals.
I use iPhoto 6.0.5 and simply backup to an external hard-disk drive.
I try not to look into my iPhoto Library, much less figure out how it works.
It's VERY arcane in there. I take Apple at their word that the ORIGINAL files
remain untouched, but I'd be hard pressed to manually FIND them!

What I'd do now: Import only the RAW image into iPhoto or your
editor/organizer of choice, and only one. Delete the other RAW file and
any JPEGs associated with it.
Then do your editing and sorting, exporting etc.
I tend to shoot either RAW or JPEG; no longer both in any given shoot.

would guess that something is duplicating images to use as thumbnails.

I see.
I can't understand how I ever got those files, because I'm very wary of
placing a file into any application, then take it out from there and
saving it. I always assume the worst; that the application somehow
changes the file, which is the reason why I've burned the photos from
the desktop after importing them (I *think* I used the "Image capture"
application for this).
However, I do believe at that time iPhoto froze a lot, so I had to do
"force quit" (it seems that iPhoto takes up a lot of CPU power at
times, and if I do other things while it's importing it often freezes),
so perhaps that's why I have duplicate copies of files now, even though
I don't understand why this has affected my backup CDs which *were not*
photos taken from iPhoto.
I have another theory though, perhaps far fetched, but nevertheless....
could it be that while importing photos to an empty folder on the
desktop from the camera, using "Image capture", a memory card reader,
or a PCMCIA slot adapter (I'm on a G4 Powerbook), that the computer
froze again, so I had to do a force-quit, then when re-importing I
would get duplicates?

I agree. I've read numerous warnings about not messing around with the
innards of iPhoto, so I haven't touched any of that.
I use the exact same version of iPhoto as you by the way.
OK, so I have my RAW and JPG files here on my external hard drive which
have been transferred from the various backup DVDs. I have a lot of
"_1.CR2" files here along with the same file in plain ".CR2". Now, the
file-sizes are slightly different (the plain ".CR2" file is slightly
bigger than the "_1") which is no issue here as I'll use the plain
".CR2" file in my library of course and trash the "_1.CR2", but I've
found lots of RAW files which are only available as "_1.CR2" !!!! I
can't find any matching plain ".CR2" files :-(
So why are the file sizes slightly different? The EXIF data seems to be
the same.
