how do you select images for slide show?

[tredlie]

Dear All

after having tinkered around with a number of photo management packages
I have now installed digikam sitting on top of my developed JPG (after
they have gone through tagging and devloping in darktable).
digikam very nicely picks up the EXIF data when importing these JPGs so
that they can be nicely used for searchint etc.

Now I would like to create a number of slideshows for varying purposes,
like Vietnam-10min or/and Vietnam-30min so that I can mayby copy the
corresponding files to a memory stick for a slideshow presentation.

A simple and - as I find - logical way would be to create a list of
those filenames that I have selected in digikam and have them linked to
the original files. Sounds simple enough. In principle this would be a
sort of 'playlist'.

Unfortunately, I have not found anything of this sort. So how do you
people put a number of slides together for repeated use? making multiple
copies just does not seem wise.

Can the batch queue system help here? At least the CNTR B seems to
collect the file names.


I cannot really believe that I am the only person who does slide shows.

thanx in advance

Tred

Hmm, you could, eg, create a tag "Slideshow Vietnam". Tag the files you want. Later turn on a filter to show only these tagged files, select them all, copy to memory stick.

In addition to tags, digikam also have colored labels, flags and ratings to
help you select :)

Thanks for the responses!

hmmm, the same answer I got from the darktable folks. None of it is
really too practical

for once: I do not think that tags should be written to the JPGs for the
sole purpose the having them included in a subset of files for
presentation.

is this really how you create a set for slide presenation?

greetings

I agree with this but unfortunately I can not offer a solution. I also have not
found a way to save slide presentations which works for me.

Well, I find those more useful earlier on in the process, to indicate
preferences and/or restrictions, if only because there are so few of them.

Personally, I find a hierarchy of tags the easiest to use, in this case:
/slideshow and then subtags, e.g. /slideshow/Vietnam,
/slideshow/Vietnam/short. A /~/~/long tag would be superfluous if your
short slideshow is a selection from the long one.

As for the multiple copies problem:
I convert my RAW files to PNG (at maximum size) for further editing, but
any final file will be a JPG, scaled to planned use, to minimise the space
occupied. And for those I don't mind having several copies lying around.

And yes, I do the conversion from PNG to JPG with the batch queue:
scale to final size, a bit of sharpening (amount depending on output
medium), add metadata with copyright and contact info, and convert to jpeg.

Then, how are you going to present your slide show:
- a standalone presentation, with automatic progression, or
- manual progression while you present the images?

For a stand-alone presentation, I usually generate a video file, with all
transitions baked in.

thanks for sharing!

I see what you are doing, and, yes, I understand how it works. It just
bothers me that we do not have a simpler setup. Injecting tags is all
very well, but ofcourse it triggers backup requirements for each single
jog included in the slideshow, where actually you would just need one
file or directory that contains a link to the original file.
implementing this on top of the batch queue facility: this already
allows you to collect various images as you screen them. Being able to
somehow output theses filenames would already be enough, a little bash
or perl script could do the rest.

I have not gotten that far yet

jupp, thats an option. In my first version I would likely add some
talking, then it needs to be manual.

I tend to use the color labels to different subsets within an album, if there
are more uses. Sometimes, in simple cases, I just use the rating, because it
is very easy to use (ctrl + #)

You don't have to have digikam write meta data to your files.

How can the database entries of the pictures are deleted no longer
exists on the hard drive?
In my photo directories outside of digikam some pictures and directory
are deleted or moved from the Explorer.

Dear All
along with the good suggestion in particular from Remco I have managed
to setup a system that allows efficient definition and storage of
"playlists" for slide shows for me. It is actually what Remco suggested:
define hierarchical tags (see below). What I was not aware of is that
the JPGs are not at all touched with the creation of new tags: instead
they are apparently only stored in the database. Which is just fine as I
do not want the upstream defined tags to get messed up. Perfect!

One little issue remains: for a slideshow I need to export the slide
selection  which normally includes a resize. Ideally, digikam would just
allow an export with the provision of being able to resize.
Closest to this is the EXPORT TO REMOTE COMPUTER und EXPORTs. here at
least you can specify any directory. But then I would need to used
gwenview or something else to resize.

Any idea how that can be handled efficiently? This should be job for the
batch queue manager, but I dont really know how.

Thanks again

Tred

That would indeed be a job for the batch queue manager, which can do the
resizing and the conversion to JPG quite handily. What it /can't/ do (yet?)
is 'export to remote computer', but it can write the converted file to a
directory you specify (within Digikam's album structure). It can also apply
a change to the name for the converted file.

Another option (easy under Linux): export the full-size images from Digikam
to your slideshow directory and then use imagemagick to do a batch
conversion of the exported files (from a command line, also easy to put in
a script). Something like:
---------------------

#!/bin/bash
 for a in *
  do    
    convert $a -resize '1800x800' -unsharp '0.3x0.1+1.0' ../${a%.*}.jpg ;
  done

---------------------
[all files in the current working directory get resized to fit within
1800*800, and a sharpening is applied, then the results is saved in the
parent directory (don't ask...) with a .jpg extension.
*Try it first on a set of copies!* no guarantees that it works for you...]

That is actually what I prefer, as it allows me to generate different
output sizes easily, and Imagemagick can resize in such a way that the
converted image fits in the rectangle you specify, while respecting the
aspect ratio of the original.

And, don't forget to apply a little bit of sharpening after down-sampling
your images; they'll look a lot better (unsharp mask at radius 0.3 pixel
and 50-100% is what has been suggested as a basis).

Hope this helps

Remco

Hello,

when I start the program maintenance tools under the Rebuild Thumbnails
and changed o Scan for non-cataloged items,
are always creates the thumbnails on each pass of the same photos.
How can this problem be fixed?

Why don't you "export" them in a folder inside Digikam hierarchy, using the batch tool; I do that all the time I need to export resized/watermarked (and whatever you want to do) pictures. They remain in this Export folder until I don't need them anymore, then I delete them.

Appreciate it's nor Digikam but you could use feh, although it is a cli
programme. You can write scripts for it with a range of display settings and
leave Digikam completely untouched.
