Tag image with number on EOS Camera

Hi!

How difficult is it to write a number into an image?
I've got a EOS 350D and a EOS 500D. In future I'm going to use 500D only.

I would like to set a number of four digits in the menu, which is saved within the EXIF data of each picture.
This function would be really useful as I could pre-organize my pictures on the fly with numbers.
So, 0005 for flower pictures, 0024 for animal pictures for example.

As far as I know, no-one has succeeded in changing the info that is written in the Exif data

I can create multiple folders in my 5D Mark II and select them through the menu.

The information could be stored within the filename as well if EXIF changes are impossible.

Is that a build in function?
So you create some folders and select your shooting directory?

Actually, the filename structure is very specific and cannot be altered. Usually follows IMG_nnnn structure where nnnn are sequential numbers.

Yes. You can create multiple  folders following the structure nnn between 100 and 999 followed by 5 alphanumeric characters including an underscore. You then simply use the menu to select your desired folder. I don't know if this can be implemented in CHDK. Just pointing to it as a possible solution.

Ok, that's quite interesting. I just read the 5D's manual.
But unfortunately I don't have that camera.
It just a software based feature. So it must be possible to write such a function for another camera type like the 500D as well, right?

The filename change could look like IMG_nnnn_iiii
The suffix "iiii" would be the identifier.

It has alrady been said, but the filename structure is a standard that camera makers adopted after years of incompatibility.

Breaking that standard would be a bad idea, with consequences such as no longer being to print photos on the direct-print "thingies" or even seeing the photos in your camera.

I was thinking a but a lua scrip to rename photos after shooting but that would not work, because if you rename a file (for example) from IMG_1230.JPG to IMG_1230_002.JPG, the next photo will be called again IMG_1230.JPG, as the camera sees that number as available

Thank you!
I didn't know there is such a specification for the for the file system.

Maybe there is another way to pre-order pictures. Does anyone have an idea?
Or is there another camera (Canon, Nikon, Sony etc) which is able to tag photos on the fly?
