Someone correct me if I'm wrong, but the sequence numbers Lightroomor CaptureOne Pro (I'm currently using both) supports in file naming (at import or export) are not continuous, right? In other words, if I import or export 100 images today, and then in a few days import or export another batch, it won't continue at 101 unless I manually tell it to start there. Right?

If so, is there another way to accomplish that, either in the filename or in metadata -- and to do so automatically irrespective of what camera, card, etc was used? Literally a continuously running sequence? A plugin or setting that I've missed?

What I'm effectively trying to achieve is a "serial number" of sorts for all of my photos. Every single photo that gets imported and its variants/clones -- and then preserve its "serial number" any time it's exported so one can easily identify it by referencing the serial number in the filename or by backside prints.

What you can do is to add the year, month and date to the filename. With this you can have unique filename. The only problem you will have the filename numbers will not be consecutive.

You can use this question/answers as reference/idea

quotes from some of the answers:

rename the files to include the original shooting date. So instead of IMG_0001.JPG you might end up with 20110214-0001.JPG

instead of IMG_1234.jpg, have the file renamed to IMG_YYYYMMDD_1234.jpg. That way if later down the road you have another IMG_1234.jpg, the exported versions would be dated. So if the images were shot on Feb. 14, 2010 and Jun. 30, 2011 you would end up with IMG_20100214_1234.jpg and IMG_20110630_1234.jpg.


You can easily create custom templates in COP that will auto-name or auto-rename your files on export. You can set the parameters as you wish. steps 1 and 2
