filename format updates??
« on: April 28, 2017, 07:02:53 AM »
Hey gang, two questions..
1. why does canon not have custom file names on all camera bodies? I know its on the the high end bodies.. is it just a $$ games with options?

2. I have searched the rumors board and I see as far back as 2012, isnt it time Canon updated its file name format?
I am using the 7D MarkII and have a custom Name with my Initials and a 5 digit #  Example  RSB8xxxx.CR2
this way I sort of keep up with the # of shutter clicks and limits my Dupe file names. And I can group my pictures in groups of 10k.

As I start to approach  the 100k Mark for photos taken, I see that I have to alter may prefix to support that  range.  Not that I dont have to change at the 10k mark already.

I would think that now its 2017 isnt it time for a new format?  maybe allow a 6 digit # by default?

Probably most users of less expensive cameras will never use such a function. Sometimes, too many options are confusing for some kind of users. Being able to use complex naming schemes may suit the pro, but IMHO not many casual photographers.

2. I have searched the rumors board and I see as far back as 2012, isnt it time Canon updated its file name format?

I usually rename files on import, so it really doesn't matter what the original filename on the card is.

The question about file naming formats pops up every few months.  The EXIF and DCF specifications would probably both have to change.  Its possible that every piece of imaging software might be affected if the DCF / EXIF had a major format change.  Imagine the howls that would go up if everyone had to purchase the latest software version. 

Standards are a good thing, but they are also difficult to change because of the financial impact.


Design rule for Camera File system (DCF) is a JEITA specification (number CP-3461) which defines a file system for digital cameras, including the directory structure, file naming method, character set, file format, and metadata format. It is currently the de facto industry standard for digital still cameras. The file format of DCF conforms to the Exif specification, but the DCF specification also allows use of any other file formats.
The latest version of the standard is 2.0 (2010 edition).

Directory and file structureThe filesystem in a digital camera contains a DCIM (Digital Camera IMages) directory, which can contain multiple subdirectories with names such as "123ABCDE" that consist of a unique directory number (in the range 100…999) and five alphanumeric characters, which may be freely chosen and often refer to a camera maker. These directories contain files with names such as "ABCD1234.JPG" that consist of four alphanumeric characters (often "DSC_", "DSC0", "DSCF", "IMG_", "MOV_", or "P000"), followed by a number. DCF 2.0 adds support for DCF optional files recorded in an optional color space (that is, Adobe RGB rather than sRGB). Such files must be indicated by a leading "_" (as in "_DSC" instead of "DSC_" or "DSC0").
The file extension is "JPG" for Exif files and "THM" for Exif files that represent thumbnails of other files than "JPG". Other file formats use different extensions. Multiple files sharing a number (even if the file extension or the four alphanumeric characters are different) are considered related and form a DCF object. Prior to the introduction of DCF 2.0, some camera vendors (e.g. Minolta and Konica Minolta) chose to use the file extension to indicate the recorded color space, that is, "JPG" was used for sRGB, whereas "JPE" was used for Adobe RGB.
For example, the files on a Nikon D40 are arranged according to the above specification. Thus, a card formatted by the camera will have a volume named "NIKOND40", with a subdirectory named "DCIM". This directory contains a subdirectory named by default "100NCD40", in which images are stored. Images are named "DSC_xxxx", where xxxx represents the file's sequential number.
As this is an industry standard, similar directory structures and naming procedures can be found in most digital cameras.
An example of DCF directory and file structure:
 
  • Root
    • DCIM (directory)
      • 100ABCDE (a DCF directory)
        • ABCD0001.JPG (a DCF basic file or DCF optional file)
        • ABCD0002.JPG
        • ABCD0003.TIF (a DCF extended image file)
        • ABCD0003.THM (a DCF thumbnail file for extended image file; it is not allowed for ".JPG" files)
        • ABCD0004.WAV (a DCF object need not include an image file)
        • ABCD0005.JPG
        • ABCD0005.WAV (a DCF object formed by naming non-image file with the same file number as an image file)
        • ...
        • ABCD9999.JPG
        • README.TXT (other file names and extensions may be assigned freely)
        • ETC (directories other than DCF directories are also allowed; they shall not have the same name as DCF file)
      • ...
      • 999ABCDE (a DCF directory)
        • ABCD0001.JPG (a DCF basic file or DCF optional file)
        • ... etc.

 :D Thank you for the detailed reply. I knew of standards, but I figured it was a internal standard.  I didn't stop to think about all the other related issues. For the moment, I will adjust as best as I can to internally adjust the name.  But on other camera's that I cant I use Bulk Rename utility to alter the files after import. But I try to see the file Seq # to associate with the number of Shutter clicks.  Thanks again for the info.. Happy SHooting!

With lightroom, and probably most pro level software, just set the file name and beginning number you want before importing it.

I agree!
On my 7D2, I have my file names set to D(for Don)YY(for the year, now at 17)B(a letter that I increment every 1000 photos)XXXX, so a recent picture might be named D17B4567.CR2....

On my 6D2, I am forced to use IMG_XXXX so after only 10,000 pictures, I get duplicate file names. That SUCKS!
