Rename Duplicates

I am trying to find out how I can rename my images an indicate when there is a duplicate:

Currently I have A rename rule that renames the file:

YYYYMMDD_hhmmssSSS_#

however this does not fully produce what I wanted, the # which gives me a sequence, what do I change to show a Duplicate?

e.g.

20201117_092030001_1
20201117_092030001_2
20201117_092030001_3

20201117_093035002_1
20201117_093035002_2

20201117_095026002_0

Many thanks...

Not clear on what's going on here. How are you determining duplicates?

When the image has the same date and time in full down to the millisecond

Many thanks

Paul

But you are just going by the name or are you checking other metadata? I guess I'm not seeing the difference between adding a number at the end and what you are trying to do. It's unclear whether your examples are the "before" or "after".

Yes, you are correct, I am not checking anything other than the date and time...

Is there a better way to do this?

Paul

I'm still unclear. Can you give me a clear example of files before renaming and after? I still don't know whether your previous example is what you want to happen and if so, why the current way of files having a number added onto them isn't sufficient.

sorry I have not my requirement not clear...

if I have the images as there are named out of the Camera

Img_00001
Img_00002
Img_00003
Img_00004
Img_00005
Img_00006

because I have taken these images from the camera I also check that I have process them before as I keep a Backup and also a SD Card Backup

currently I rename them I get this into my catalog:

YYYYMMDD_hhmmssddd_0011
YYYYMMDD_hhmmssddd_0012
YYYYMMDD_hhmmssddd_0013
YYYYMMDD_hhmmssddd_0014
YYYYMMDD_hhmmssddd_0015
YYYYMMDD_hhmmssddd_0016

However from the above, I cannot determine if the photo already exists as when I rename the images as above and move them to my catalog, I may have already process one or two before.

e.g.
rename images 20201117_093035002_0010... maybe already in the catalog as 20201117_093035002_0001

that is why I would like to rename my catalog again to get the:
20201117_093035002_1
20201117_093035002_2

Many thanks in advance...

I'm still a little fuzzy here but how do you know that 20201117_093035002_0010 is the same image as 20201117_093035002_0001? How about 002...009?

I only know when reviewing them in Lightroom or Bridge and look at the metadata...

so I do not want duplicate images in my catalog folder, I wish to place them in my Duplicate folder...

Paul

What specific things do you look at? I'm still not getting a grasp on how you intend to automate this.

In Lightroom I look at date time created, lens, SS, F Stop and ISO...

however I do not need this in the name...

Sounds like you need a custom script to handle that type of thing. A good deal beyond the support I can give on this.

when you say custom script... what is this, what is it written in?

Paul

You can either do AppleScript/JavaScript or use any shell scripting language you want. I suggest you do a search for scripts on this forum to get a sense of what they are like.
