Re: D50 File Numbering

Nothing there explains the cause. Photos 5243 to 5308 were in folder
100 along with a few from the day before.
From folder 100
5243 was taken at 4:30PM
.... more at short intervals and then
5251 was taken at 4:41PM
5252 was taken at 4:41PM
.... more at short intervals and then the last one
5308 was taken at 5:00PM

In folder 101
5251 taken at 5:03PM
5252 taken at 5:03PM

The card didn't come out of the camera in that time and no photos were
deleted. I have them all on the PC. It was sunset and I took lots of
shots, a sequence of 11 of them are on Flickr, but the exif is
removed.

After that, as I said, I formatted the card and took another photo and
it's 5253. So it looks like the numbers up to 5308 will be re-used.

:

: O.K. There are not enough images in that first folder to
: account for the creation of a second folder. Normally, that happens
: either when there are 999 images in a folder, or when the image
number
: reaches 9999.
:
: What I *think* happened here is (assuming that you deleted some
: images in a card reader on the computer and then re-inserted the
card in
: the camera) that the camera started reading through the
highest-numbered
: folder looking for the end after finding the first image number in
that
: folder. What happened is that it reached (say 5250) and saw that
5251
: was not present, it set the number to 5251, without bothering to see
: whether there was anything beyond that (after all, that takes longer
to
: get the camera started up if it does that). Then you took 5251, and
the
: next shot (5252) it discovered was already present in that folder,
so it
: created a new folder and put the remaining images from that session
: there. This prevents overwriting of existing image files, though it
: does confuse the image-numbering sequence somewhat.
:
: I've not encountered this, yet, with my D70, in part because
: I've been using 1GB CF cards, and an image size which will not get
as
: many as 999 images on the whole card, let alone in a single folder.
: However, I've added a 4GB CF card to my collection, and depending on
the
: image size, I can get well over 1000 images to a single CF card. (I
had
: been shooting with Medium/Fine settings, and going to RAW only for
: special cases. On the 4GB card, that will get over 2K images.
: Large/Fine gets over 1.1K, and only full-time RAW will get be below
1000
: images about 716).
:
: I used to have a script (unix system) which downloaded the
: contents of the DCIM/100NCD70 folder (yes, I know that on Windows,
it
: would be seen as DCIM\100NCD70).
:
: Now, since that risks not downloading everything from the card,
: my script uses tar to copy the entire tree of directories and their
: contents into the unix system, so I don't have to worry about any
: accidental duplication of filenames resulting in something lost.
:
: And, as soon as the download (and duplication to a second hard
: disk) is complete and verified, I put the CF card back into the
camera
: and format it to start over.
:
: I also reset the image number back to 0001 at the beginning of
: each year.
:
: If the image number goes past 9999 in a shooting session, it
: will (of course) create a new folder to make sure that things do not
get
: overwritten. If I need to combine them back to maintain a proper
: sequence later, I can rename the later ones from DSC_???? to
DSC1????
: and on as needed.

:
: I presume that you first safely copied the duplicated filenames
: to separate directories -- or renamed them first? I have this image
of
: the files being lost when you reformatted the card.
:
: I do sometimes delete obviously bad images from the card, if
: there is a question of room, but I tend to keep the card in the
camera
: until I am out of room or have another reason to change CF cards. I
: suspect that your problem occurred when you re-inserted the card
after
: deleting some files via an external computer. (It may be that the
camera
: keeps some information on the card to keep it from duplicating
numbers,
: and this was corrupted by the computer downloading the files.) I've
got
: things set up so my cards mount read-only (again, a unix system), so
I
: *can't* corrupt the filesystem -- and this forces me to always use
the
: camera itself to format the cards. (Besides, on a unix system, I
have
: too many options for how to format a card -- not just the FAT
: filesystems which the cameras use. :-)
:
: > The only thing that I did during the shoot was change the battery,

:
: That should not be the cause of the problem -- but if you did
: delete images from the CF card in an external computer, and then
: re-install it in the camera, *that* might have triggered the problem
as
: I described above.
:
: As I mentioned above, I *do* delete images from the CF card
: before I am done with it -- but I do so using the camera, and I've
never
: had the camera loop back to re-use some deleted numbers.
:
: I hope that this helps,
