Renaming files

[digikam-2]

Hi,

How can I rename files?

I start with img_1234.cr2, I need/want to rename it to:
dogs-vancouver-20150705-1234.cr2

* dogs-vancouver : I type it in
* 20150706: exif date created (I have figure it out)
* 1234: How do I get the last digits? I do not want the counter and
  add +1 because I want to keep the original number from the image.
* cr2: How do I get the extension?

This tells me the general topic, the location, the date of the photo
and the sequence. I do not want to use the counter +1 because before
doing the renaming, I do a lot of deleting for bad focus, bad
composition... so the numbers are not consecutive.

Then I can do it in bulk by selecting all the photos for that topic...

In Lightroom I use: {Custom Text}-{Date (YYYYMMDD)>>}-{Original
number suffix>>}

The best idea is to use your operation system tools, as digikam also
uses them.

Years ago, I realised that any type of numbering is a basis for chaos
with my collection.

Therefore I prefer a directory structure which represents certain types
of photos.
It could be in your case: pics/vancouver/animals/dogs.

For the photos themselves:

Using a tool: Before I do anything with the photos I have them
batch-renamed using the EXIF-information for YYYYMMDD_HHMMSS (24 hour
clock) in the photos plus additional information.

For example: Your photo, taken today, could change from
dogs_vancouver_123.cr2 to
20150708_132835x_collie.cr2

The "x" is used in case the camera can takes more than one picture in a
second (with bracketing for example).

This numbering allows for a natural sorting order and you can use
pictures from different cameras on the same shooting location with
clearly unique numbers, unless you shoot with both cameras a the same
time;-).

Basically my question is :

Is it possible to do substring operations on file renames? I need the
last 4 characters of the filename.

A bit off topic, but I'm curious as to what the advantage there is in
renaming image files? All that information is already in the metadata
which can include descriptions, tags, hierarchical keywords, location,
people, animals, etc, etc. The images can be organized and sorted
using the metadata and ignoring the filenames.

Yes and no.

1. Software come and go. I was using Bibble for a couple of years
when they got purchased by Corel and everything went downhill from
there. I have used Lightroom for 5 years but I do not want the new CC
where I have to rent the software by the month, just to be able to
print with a "proper crop". I can't even just rent LR by itself, I
also have to get Photoshop. What if I want to stop using it?

2. This naming scheme makes it easy to do the weekly backup and
restore the images. Over the years, I have crashed/replace/upgrade
drives 4 times. I do not need to restore everything at once. Only
what I "really" need. Then I did the "rest of the restore" over the
weekend when I had plenty of time. I can do (and have done) a bare
metal recovery (that's from a blank hard drive) in less than 3 hours
and be back "live".

3. This naming scheme makes it easy to understand what we are talking
about. Not just by me but my family. They don't how IPTC from XMP
from EXIF...

I think it comes to renaming files. There should be a number of tools
which do exactly that.

I use krename under Linux. It should be possible with digikam but I
never tried it.

You will know which box the file belongs to without opening it.
If you have thousands of pictures
one with the file name 20150708_231415x_boston.jpg gives
you a much better idea about that picture than img_2345.jpg
And, as I wrote, when working with several cameras, a mixup is less likely.

There is an advanced renaming tool in Digikam batch tool manager.

When I need to rename pictures outside Digikam, I use Krename.

Hope this helps,

Yes but how can I extract a substring of a filename in batch tool
manager? I want/need the last 4 characters of the filename

I'm pretty sure that pyRenamer will allow you to do that.  It's
standalone, not part of DK

If you look closely at the rename dialog in the album view (with several
files selected!) you see a button with a blue circle icon with an 'i' in
its center.

That button gives you an overview of what the rename dialog can do (hint:
Options [file] Modifiers {range:from,to})

You'll find the same options in the Batch Queue Manager as part of the
"Queue Settings" pane

There are plenty of options :

 [file] 

 [ext] 

 [user] 

 [group] 

 [dir] 

 [dir.] 

 [cam] 

 # 

 #[options] 

 #[options,start] 

 #[options,start,step] 

 [date] 

 [date:key] 

 [date:format] 

 [db:key] 

 [meta:key] 

Modificateurs

 {upper} 

 {lower} 

 {firstupper} 

 {trim} 

 {unique} 

 {unique:n} 

 {removedoubles} 

 {default:"value"} 

 {replace:"old", "new",options} 

 {range:from,to} 

For example, one of the rule I use for pictures I publish on line is the following:

[date:"yyMMdd"]-[file]{replace:"IMG_","",i}

And KRename can do almost anything too, but I only use for pictures that are not mine (thus not managed in Digikam DB).
