hi guys just a lil question.

you know the continous filename thingy?

well i bought a camera and plugged in a CF card. Took some pictures and then noticed that the filename was something like 105-0620

its like folder 105 and 620th shot. Now i got pissed off coz its a new camera and it already has 620 actuations? plus its lke the 5th folder so it could even be more...

so next day i hop on back to the shop and complained. they took another camera out and we placed the same CF card into it and then took a shot and lo and behold the filename is approximately the same.....

its like the CF card is the one carrying the actuation counter (via file numbering) and not the camera. Ok so i bought a new card and formatted it and plugged it into my camera and it continued the count from where the old CF card left off.....

Im confused! 2 cameras cant have the same actuation number not unless the store took out both cameras and took the same number of shots (approximately) and then storing them back in. Any ideas how this happened?

Yes, the CF card is what carries the file number over. Unless you put a virgin card in a new camera (or reset the file number in a different camera using the card) the file number will carry over from the previous camera. Unless your previous camera was a Nikon or something, in which case the folder would be newly created.
If you want to reset your camera so you can keep track of how many shots you've taken (minus the few you took already) just scroll down the menu to "File numbering" then hit "Manual reset"

how come when i plugged in a new cf card the file number continued where it left off? I knew the CF card i threw in the first time couldnt be new (it was a freebie).

In a sense that can work, but then you'll still be off the count, some what. And then you might need to reset again, so there'll never be an accurate count. That's happened for me.

grego, how come youll be off the count again after doing that? i assume youll reset manually then put it back on continous from then on. right?

If you reset, it'll start counting, but then the previous photos you took, aren't counted.

So lets say I shot 100 shots on my 30D. If i reset it would start at 0 and not count the 100 previous. You'd never have an accurate count.

Right now, I don't. I'm likely going to cross use the cards from time to time, sadly, so resetting will likely be common. It's annoying, even after formatting on my computer.

ah i see. yeah it wont be accurate, but at least ill have a continous file number and then add a few to account for the earlier shots taken i guess....thanks for the response.

but dont you think its kind of useless if your cards are the ones who store the file number?

Sadly, yes, I think it is useless, because people have a good chance of having inaccurate counts. Although Canon can give you the actual amount, but that means dealing with them. I likely won't sell my 30D, but if i did it will suck trying to give a number, because usually people want to know.

I think the idea is that the file number is the one following the higher of the count in the camera and the CF card. When you do a flie number reset the camera will create a new folder. This way, no two images will have the same file number in any given folder.

You could try this IF you have a reasonable Idea of the number of shots you have taken. I have tried it on my 20D and it works

1 - Set the camera to reset the count
2 - Put an empty card in the camera and format it.
3 - Take a shot - it will be named IMG_0001.jpg, IMG_0001.CR2 or both
4 - Take out the card and set the camera to continous count
5 - Using a card reader, rename the file(s) on the card with your computer to the number of shots you think you have taken i.e IMG_0067.CR2 / IMG_0067.JPG
6 - Put the card back in the camera and take another shot and it should be back on course.

Why does this matter? All I need is a file name that is different from any in the directory where I am going to copy it. I don't really care what the name is.

Some people like to keep track of their shutter activations. With continous file numbering, it gives you a rough idea. That is why it is recommended that if you have multiple camera bodies or you are upgrading your camera to a new model, that you format all your cards in the computer as opposed to in camera. By formatting in computer, you remove all file numbering....in camera format retains the file number info.

That will work until......

1. You get a back up camera
2. Someone borrows your CF card
3. You get multiple CF cards for multiple cameras
4. You and your friend go shooting together and you loan each other cards

Formatting in the computer will address most of this, but it's not worth the hassle of trying to keep it all straight to me. I just put all my cameras on continuos and rename my files as required when they've be downloaded to the computer.
