So I was fine with my new 20D, up to about 0472 in the file numbering sequence, but popped in an older CF card, guess there were some images on there from my old 10D, formatted it, shot a few pics, now my numbering sequence is way out of whack. My image folder now has a number of "489" not "100" as it was before, and my files are now 4879.... is there a simple fix to this?
1 Set the camera to numbering auto reset
2 Format card in camera
3 Take photo should be IMG_0001 (100-0001)
4 Set camera to continuous numbering
5 Switch off camera
6 Remove CF card from camera and into card reader in computer rename the folder 100CANON to 104CANON and rename the files to IMG_0472.CR2 (or jpg) or whatever the current number of shots taken should be note folder number should match image number 104 = 401-500 105= 501-600 etc.
7 Place CF card back in camera and take a shot, number should be the next one you want in this case IMG_0473 (104-0473).
As you can see you can set things to any number you like.
1-put card in card rader, deleted "489CANON" folder
2-set 20D to auto reset file numbering
3-put card back in
4-took picture, restored my numbering sequence.
5-set the camera back to continuous sequence
6-shot again, to test the sequence, and it was fully restored
I did this before you posted, but thanks, I will definitely watch out next time
It was thrown off by my nikon D100 sequence. It's similar on the nikons, 489ND100, except on the nikons it still stuffs more than 100 files in that one folder. I think it renames everytime you format the card... who knows...
The same thing happend to me with my 20D. I put in a card that I had been using in my D-60 and the file numbering in the 20 immediately went to the same place as the D-60, even though I formatted the card in the 20 before I shot on it. It added the folder from the D-60 card to the numbering sequence even when I changed back to the card I had been using in the 20. Weird...
As you are using a Mac I strongly recommend trying ExifRenamer, a bit of donationware which automatically renames your files based on the exact date and time they were taken, based on the EXIF data. You can even set it to move each set of downloaded images to a new folder with the date and a prefix or suffix that it asks you for.
Then it doesn't matter what the camera is doing to the file names.
That's a shame, I'm using a 10D so wouldn't have noticed.
It might be worth sending him a sample file: "Should ExifRenamer have problems with a certain file format, I'm willing to analyze the format in question; in that case, please give me access to one or more test files."
